well i wired up my motor and it runs good and starts good i still need to get wire and stuff but i had some extra wire laying around so i tried it and it worked i don't have fuse links on it either but i will. i have the positive from the battery going to b+ on the starter solenoid and a wire from s on the starter solenoid going to the ignition switch and on the alternate b+ is going to the firewall and that other wire i was talking about it is coming off the positive and going to the firewall so vile is this right?

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)

I'm glad to see Hotrod is getting this thing sorted out. I wonder if the guy who did that butch job every thought he will amount to 77 posts worth to just for somebody to put the thing back the way it was designed in the first place ::) Carry on,  Lorne

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.

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?

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?

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

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