i have a 79 chevy k10 with a 350 i picked it up salvaged i put a new 350 in and i was going to wire it up to the starter an there is not a ignition wire that goes to the small post on the starter is this common or do i have to put one on if so do i run he wire fro the small post on the starter straight to the ignition switch or do i run it to the ignition coil then to the ignition switch? if anyone knows please let me know its the only thing left then i can start it

My question is where did the wire go? The battery cable positive goes to the B+ terminal on the starter and the S terminal comes from the ignition switch.
-
well the battery cable is on the big post and there are two wires connected to one eyelet that fits an he same post as the bat cable and those are the only wires i have i tried to put the wirs with the outlet on the small post but when i connected the battery it arc'd(http://www.autozone.com/images/products/vlu/vlu3510003.jpg)
-
also when i disconnected the original starter the bat cable and the two other cables (i'm guessing is the fusable link) were connected to the big post ant there was an eyelet attached to the small post but no wire in it.
-
Well you need to find the wire. It probably just seperated. As far as it arcing, your b+ connection is probably touching the starter housing.

Last weekend I put a new starter on my 91 sub. Boy, the difference! I replaced it because the solenoid was acting up--had to tap on the starter housing twice in about three months to get the thing started. (stuck solenoid). That puppy turns my 350 over so quick now, i couldn't believe the difference.
Anyway, the B+ big positive cable has a type of hook on the eyelet that goes over the post, and hooks in place to prevent the cable from twisting any. It is a close fit with all the wires, fusible link, ground of the casing, etc so you have to be careful when putting the wires back.
Yes, the fusible link little red wire goes on the smaller post below the B+, with an eyelet to keep it on--it is a very small nut, smaller than a 3/8 inch wrench.
I hate changing starters on a 4x4, with the hogs head in the way, and the bracket from the frame with a rubber bump stop--had to take that off to get the starter off.

???
The fusible links should attach to the same B+ terminal that the battery cable goes to. The S terminal is the switched ignition wire.

Sorry, that's what I meant. The fusible link red wire is a little smaller and the two go on the big post. :o
-
thanks for the responses i really appreciate it. if i can't find the wire where can i trace it from? the ignition switch? or coil?
-
The wire should be coming from the junction block on the firewall, it is shaped like a diamond, wires should come off of it and split and go to the alternator and the starter if I am remembering correctly.
-
great thanks again when i get home today i'll search for it!
-
The S terminal wire comes from the ignition switch to the neutral safety switch. there is one connector and then it goes to the S terminal on the starter solenoid. It is only energized when you are holding the key in the cranking position in Park or Neutral.
-
where might i find the neutral safety switch?
-
on the steering column inside the cab right before it exits the floorboard. it is white and is crescent shaped
-
You have to get on your back and look up to the steering column from the floorboard. It is on the top side of the steering collumn. Its a pain to get to, but, changing it isn't too bad. If I remember correctly, you have to place a pin or something to hold the position of the switch as you install it. Two screws, then pop the wires off.
-
if i have to replace the wire can i use a 10 gauge wire?
