Title: wiring
Post by: hotrod24 on February 25, 2008, 11:11:08 PM
when i say my truck is messed up i don't just mean the cab there is a ford solenoid on my fire wall see 2 is the cable that goes to the starter and the 1 goes to the ford solenoid i thank there is supposed to a wire coming from the junction block and going to the starter solenoid on the starter but the wire on the solenoid is cut off

 Looks like Abdol the butchers truck.
 Some guys try to cure the hot no start with the phord solenoid instead of just fixing the starter,are those headers in the bottom pic?
 If it works, just try to clean up the wiring mess a little or rewire back to factory. You didn't state what year you have.

there is a 78 wiring harness in it and there is headers on it is there any way that i can check the starter
Title: Re: wiring
Post by: joesgarage71 on February 26, 2008, 11:54:27 AM
If it ain't broke don't fix it.
 You could fix the wires so it don't look so bad, rap them in conduit (black plastic stuff) keep them away from the heat and moving parts
 Some part stores will be able to test it on the truck, but most will want you to take it off and bring it in. Truck headers(most all headers) come real close to the stock starter. On the stuff I have headers on I buy a mini starter for the other trucks I use stock manifolds on and use mufflers to get the sound I want.
 I can scan a diagram for your 78 if you want to return to stock.

An older fellow I know (a retired Rockwell engineer) puts a Chrysler starter relay on EVERY vehicle he owns, the newest being a '70 Nova w/a 502 & Holley fuel injection. He has one on his '66 Chevy truck & his '64 Chevy II. I asked him one day. Whats the deal? He said that way the ignition switch doesn't have the full load going through it on cracking, ??? I didn't know everyone was having problems with that wire ;) ;) To each his own I guess. Yes I agree, eliminate it, less connections,less problems.
Title: Re: wiring
Post by: VileZambonie on February 26, 2008, 04:11:36 PM
Yeah Chrysler used a low current ignition switch thus the starter relay. That's how most manufacturers started doing it up until the last few years. Now the PCM controls the starter relay and most have built in overload protection to prevent you from continuous cranking.

To test the starter, doing it out of the vehicle is essentially useless since there's no load on it. To test the starter circuit you need a current probe, and a voltmeter.

is there a way that i could put a screw driver on the starter and turn it over
Title: Re: wiring
Post by: VileZambonie on February 26, 2008, 09:07:19 PM
What exactly are you trying to do? Is your starter not energizing?
Title: Re: wiring
Post by: hotrod24 on February 27, 2008, 12:42:12 AM
i just wanted to see if my starter still worked because if my starter does not work and i rewire it i would have done the work for nothing
Title: Re: wiring
Post by: VileZambonie on February 27, 2008, 04:48:18 AM
 ??? Are you saying when you crank the ignition switch nothing happens?

You haven't said if there's a problem only that you don't like the way it's wired.

Post by: hotrod24 on February 27, 2008, 04:09:57 PM
sorry vile i want it to be stock. my problem is the starter it must work because it cranks the truck, so my question is, do i need a new solenoid for the starter? 
Title: Re: wiring
Post by: Captkaos on February 27, 2008, 05:04:09 PM
What is wrong with the starter if it cranks the truck?  If you want it back stock remove the solenoid on the firewall and run the wire on the junction that it was tied into back to the solenoid.
Title: Re: wiring
Post by: hotrod24 on February 27, 2008, 05:14:15 PM
i thought sense there is a ford solenoid on it the starter solenoid might not work
Title: Re: wiring

Still  ??? If you turn the ignition switch to the crank position does the truck start?
Title: Re: wiring
Post by: hotrod24 on February 27, 2008, 05:33:59 PM
yes it does crank but i have to pat the gas old motor it is like it don't have  enough power
Title: Re: wiring
Post by: Captkaos on February 27, 2008, 05:38:11 PM
If it turns the motor over your starter is fine.  If you have to give it gas for it to crank you have a fuel or spark problem.  Does it ever crank and run?
Title: Re: wiring
Post by: hotrod24 on February 27, 2008, 05:44:05 PM
yes it will crack and run fine if i crank it and turn it off and Wait a minute it will crack right back up with out patting the gas

Title: Re: wiring
Post by: Captkaos on February 28, 2008, 10:26:14 AM
Yes that diagram will help, but you just need to remove the Remote solenoid and put the stock on back in the loop.
So it is that you just don't like it then.  I was thinking that at first and then started thinking you had a problem cranking it...

Title: Re: wiring
Post by: VileZambonie on February 29, 2008, 06:43:54 AM
Do yourself a favor before you begin this task. Get yourself a 40W soldering iron, flux, 1/16" 60/40 solder, heat shrink, a terminal assortment kit, a roll of 16 gauge fusible link, 12 and 14 ga wire and some electrical conduit.

Now one question I have is is the wire coming off of the ford solenoid going to the M+ terminal on your starter and bypassing the starter mounted solenoid?
Title: Re: wiring
Post by: hotrod24 on February 29, 2008, 01:08:14 PM
no the only wire that is going to the starter is the positive coming from the battery now it looks like a wire was cut off on the starter it is yellow you can see that in the starter pic i posted
Title: Re: wiring

only thing going to the starter is the positive and there is another wire coming off of that wire going to the block on the firewall
Title: Re: wiring
Post by: VileZambonie on February 29, 2008, 03:23:38 PM
If that's the case there is no way your starter would energize. You need to look at your starter again more closely.
Title: Re: wiring
Post by: hotrod24 on February 29, 2008, 04:31:58 PM
there is a wire coming from the block on the firewall and going to the positive it is wired in to the positive on the battery that i think is taking up for the wire that you are talking about

Title: Re: wiring
Post by: VileZambonie on March 01, 2008, 07:19:02 AM
Well I hope for you it's warm out. It's snowing like crazy here. You need to follow those 2 black wires off of the solenoid and let us know EXACTLY where they are going. It also looks like you have no circuit protection from your battery. This means any of that cheesy wiring arcs to ground there's no stopping the battery from continually feeding all of it's potential current through those wires. That means your truck will most likely catch on fire and at the very least you will burn up your wiring harness. There should be a fusible link coming off of the B+ terminal at the starter and at your junction block on the firewall. Typical fusible links are 2 gauges smaller than the intended wire they are connected too.

Yep, and if you haven't seen a fusible link on before, the insulation on the fusible link is thicker so the overall diameter of the wire looks like the wire it protects, but more flexible melts away rather than catching fire.

yes there is a another wire going to the starter and it is black i know it is my fault that i did not see it the first time but this should be good and i thank it is going to the b terminal i do not know if it is coming from the firewall but i think it is you can see the black wire in the pic

Title: Re: wiring
Post by: autorepr on March 02, 2008, 09:53:54 AM
To make a long story short all you need to do is remove the ford solenoid and all it's added wires and connect the factory wire  to the S terminal on the starter solenoid. Just take a length of 12 ga wire (I think the factory color is purple) and butt splice it with a seal-o-crimp butt splice to the fact. wire in the harness where they connected the "green wire" to. Then run it down and connect it to the starter S term.  with a seal-o-crimp ring terminal. Loom it with plastic split loom and make sure it's away from hot things and strap it so it won't rub anything and short to ground.

The seal-o-crimp terminals are regular terminals but have a heat shinking plastic "housing" covering them and a glue in it. When you heat it it shrinks down and the glue melts and bonds to the wire jacketing. It makes a great perminant connection.

Now about that battery cable... Replace it with a cable that is as short as possible and is single ott size and has an acc lead coming off the end that connects to the battery, add a fuse link if it doesn't already have one and connect it to the factory wire, again using the seal-o-crimp connectors. Strap the end going to the starter to the engine block so it doesnt lay agianst or rub anything hot.

Post by: hotrod24 on March 02, 2008, 02:14:31 PM
yea i want it wired up like it just came out of the factory and the purple wire that is on the solenoid is going to to the stater so some things i guess is right
Title: Re: wiring
Post by: hotrod24 on March 02, 2008, 10:49:59 PM
ok the green wire is the ignition switch and the purple one goes to the starter and the light red one goes to the battery and the dark red one goes in behide the motor but i do not think that it goes to anything so where should i start oh how do you tell what is b and what is m and s i look on the starter but did not see it

Title: Re: wiring
Post by: Captkaos on March 04, 2008, 03:34:54 PM
Where does that wire go?  That isn't on a factory setup if that is what you are getting at.  The S terminal is the outside one looking from the front (there is a wire on them in your picture above).  They are also labeled on the solenoid.
Title: Re: wiring
Post by: VileZambonie on March 04, 2008, 04:50:55 PM
Your positive battery cable needs to go to the B+ terminal on the starter solenoid. On that same post you should have 2 wires each with a fusible link. One wire should go to the junction block on the firewall and the other wire should go to the B+ terminal on the back of the alternator. The feed wire coming off of the junction block should also have a fusible link. These are critical, without them you have NO circuit protection.

The S terminal on the starter solenoid is closest to the engine block and should go to the ignition switch (P/N or NSS should also be in series).

Proper gauge and length fusible link wire -(Typically a fusible link is two wire gauges smaller than the wire it is protecting)


First select the appropriate terminal and fusible link wire gauge needed. The link should be about the same length as the original.

No your other wire coming off of your battery terminal should be cut and eliminated. That should be a fuse link wire off of the B+ terminal on the starter. you can run the one off of your battery if you choose to but you need to have circuit protection there (fusible link)

Title: Re: wiring
Post by: VileZambonie on March 07, 2008, 04:52:22 AM
No.

The fat battery cable goes to B+ on the solenoid. There is no circuit protection on this wire since it carries several hundred amps of current so you need to route it cautiosly and away from heat etc. On the same B+ lug on the solenoid you should have 2 wires with fusible links. One goes to your junction block and the other to the B+ terminal on your alternator. The little wire on your Battery cable at the battery can be cut and removed.
Title: Re: wiring
Post by: hotrod24 on March 07, 2008, 01:25:13 PM
ok if i have a wire coming from b+ on the alternator to the starter solenoid should i have a wire going to the firewall from the alternator too?
Title: Re: wiring
Post by: VileZambonie on March 07, 2008, 02:13:25 PM
NO! lol You should have the big fat battery cable going to the B+ terminal on the starter solenoid. On that SAME terminal two more wires both with a fusible link. One goes to the B+ on the back of your alternator the other to your jucntion block on the firewall. Capische?

Title: Re: wiring
Post by: VileZambonie on March 07, 2008, 08:08:14 PM
The wire that goes from the S terminal to the ignition switch is purple and is a 12 gauge wire.

On the B+ terminal at the starter solenoid you sould have a 14 gauge fusible link spliced to a 12 gauge wire that leads to the junction block on the firewall.

On the same B+ terminal on the starter solenoid you should have a 16 gauge fusible link that is spliced to a 12 gauge wire that attaches to the B+ on your alternator.

On the other terminal on the junction block on the firewall you should have a 16 gauge fusible link that is spliced to a 12 gauge wire that goes to your bulkhead connector on the firewall. That terminal is a powerfeed to the instrument panel fuse block

ok i get it should i just get all of this wire so i will have extra wire just in case i need it and you said that have should have a bulk connector on my firewall i do not have one well i did not see it
Title: Re: wiring

The bulkhead connector is on the drivers side. It's where all your wires pass through the firewall into the cab.

is there any techniques that you have with a soldering iron i have not used one in a long time
Title: Re: wiring
Post by: VileZambonie on March 08, 2008, 07:53:01 PM
use a nice clean tip 35watt or better iron. If you have an old piece of crap buy a new one. You can get one with a hot knife tip too for like $12 bucks. The hot knife is great for cutting the radio bezel nice n clean.

use good flux and 1/16" 60/40 solder. Keep the heat and the solder flowing. The better the flow the better it will penetrate so don't be afraid to feed in extra as it may drip. The solder should penetrate all the way through the joint.

no.... I'll take a pic when I get a chance. It's where all the wires meet and go through the firewall. It's big and square and has a bolt in it. You can't miss it.

The feed wire coming off of the junction block should also have a fusible link. These are critical, without them you have NO circuit protection. ok this is what you told me is this the wire with the bulk connector that you was talking about if it is i am on the right track
Title: Re: wiring
Post by: VileZambonie on March 09, 2008, 07:53:35 PM
yup
Title: Re: wiring
Post by: hotrod24 on March 10, 2008, 12:30:28 AM
ok i got the wire i am ready oh when i am doing this could i use a butt connector to
Title: Re: wiring
Post by: VileZambonie on March 10, 2008, 06:27:10 AM
A butt connector for what? If you are soldering your joints you don't need a but connector. If you are joining more than one wire you can use a splice clip but splice clips are also soldered in. Butt connectors = potential resistance and open circuits. Stay away from them.

ok

Post by: hotrod24 on March 10, 2008, 12:36:21 PM
can i use something other then a soldering iron to do this i went to the store and i read the back the package and it said it contains lead and i have had heath problems in the past and should not be around it i love working on these trucks and i want to fix it so can you tell me another way
Title: Re: wiring
Post by: VileZambonie on March 10, 2008, 01:51:23 PM
60/40 lead + tin. Wear gloves and don't lick your fingers without washing them. I've never known anyone to get sick or have health problems over soldering a few wires together. I think you might be a little paranoid. Wheel weights have lead, almost every single chemical or product causes cancer in one animal or another (especially in California lol) Almost every clutch or friction lining contained or still contains asbestos along with several gasket materials, exhaust gasses are toxic, fuel vapors cause cancer.... etc etc. If you are that worried about it you seriously should consider having the work done by a mechanic. Your only alternative is to butt/ crimp connect everything.

yea you are right
Title: Re: wiring
Post by: hotrod24 on March 12, 2008, 09:10:03 PM
ok you told me to do this On the same B+ terminal on the starter solenoid you should have a 16 gauge fusible link that is spliced to a 12 gauge wire that attaches to the B+ on your alternator. ok i was going to do it like you said and i found this ok, the two wires that are going over the valve cover are going to the alternator and the one going under the distributor is going in to the firewall, i think it is the feed wire and the wire going straight up was going the to block on the firewall.

OK good, just make sure there is a fusible link on that wire where it attaches to the starter solenoid B+

Hotrod, Glad to see your beating it. A couple of things I noticed, I lost my first Chevy truck due to a fire. It had a fuel hose/filter rig like yours. I know there are lots of vehicles driving around like that, but I would like to see less hose,clamps & connections up there. Also, when your done, be sure to put a boot on the alternator stud/nut, having the metal fuel line touch that could quickly ruin your hard work. The other is a question. What looks like an oil pressure sender for a gauge (between the heater hose & the fuel line) what is that screwed into? Lorne

Post by: hotrod24 on March 13, 2008, 07:12:14 PM
yea that is what i am trying to do i have seen peoples trucks catch on fire and i do want that to happen so i am trying to fixes stuff. the little gold thing on my intake it screwed in the back of my motor i think it is a oil pressure sender
Title: Re: wiring
Post by: HAULIN IT on March 13, 2008, 07:18:52 PM
Ok, In that picture it is just sitting there, sticking up like that? After seeing the wiring job someone did, thought no question was foolish on this one. Good Luck & Have Fun, Lorne

hey i just wanted to see if i am do this right ok the first pic is a 12 gauge wire with a 14 gauge fuse link this one goes from the stater to the block on the firewall and the second one is them wires i was talking about earlier i did not know what gauge it was so i put 2 gauges smaller like you said before.

so vile what do you think am i doing right
Title: Re: wiring
Post by: VileZambonie on March 14, 2008, 04:02:57 PM
I think so.... however it looks like your fusible link is too long. they should be about 6" long
Title: Re: wiring
Post by: hotrod24 on March 14, 2008, 04:10:35 PM
that is what i thought i need some more connectors so as soon i get them i will Finish
Title: Re: wiring
Post by: hotrod24 on March 17, 2008, 04:22:28 PM
hey just curious do i need to put a fues link on the wire that goes to the s on the starter from the ingnition switch
Title: Re: wiring
Post by: VileZambonie on March 17, 2008, 05:05:55 PM
No that wire is circuit protected through the ignition switch circuit protection.
Title: Re: wiring
Post by: hotrod24 on March 17, 2008, 06:37:57 PM
ok good i put some of the wires on the starter does this look good

Title: Re: wiring
Post by: VileZambonie on March 17, 2008, 08:14:37 PM
NO, route them away from your header! Turn them towards the engine block especially your B+ cable. Make sure they are secured. You should wrap them away from the exhaust as much as possible. You have it connected right though!
Title: Re: wiring
Post by: Captkaos on March 17, 2008, 09:46:41 PM
Yeah for sure.  Flip the B+ over to the block side and put some zip ties and wrap it up.

ok thank you
Title: Re: wiring
Post by: DnStClr on March 17, 2008, 10:42:14 PM
hotrod, if I may add a small note- there should be 2 brass nuts on the stud coming out of your starter. The lower nut is used as a backup for the 2nd nut, with the wire terminals sandwiched between them. Using 2 nuts helps make sure that you don't overtighten and pull the brass stud loose. Ok?
Title: Re: wiring
Post by: hotrod24 on March 17, 2008, 11:54:26 PM
yea there are to nuts there the first one come lose so i tightend it

hey vile what does the block on the firewall do i only have that one wire going to it from the starter
Title: Re: wiring
Post by: VileZambonie on March 22, 2008, 07:44:29 AM
are you talking about the junction block on the firewall? The other peg should have a fusible link and a wire going to the field circuit on your alternator and you should also have a power feed fusible link to your fuse panel.
Title: Re: wiring
Post by: hotrod24 on March 22, 2008, 10:51:03 AM
yea i am talking about the junction block well all them wires i showed you i thank one of them wires goes to the fuse panel and one goes to the alternator and the one going straight up i put it on the b+ on the starter solenoid with a fuse link

ok if i get some of the spit loom will i be good
Title: Re: wiring
Post by: VileZambonie on March 22, 2008, 02:33:33 PM
tape up any exposed connections or coat them good with liquid electrical tape. Then put all your wires nice n neat in the looms. Secure them and keep them out of harms way and you'll be good to go.
