I just replaced my original starter with one from a pontiac 350 just wondering if the third yellow wire coming from the coil needs to be hooked up? There were only two terminals on the solenoid I replaced and there were three on my original. I got it to turn over but now it will not start. Someone told me that the yellow coil wire coming from the starter was not needed as it was just something with the voltage? I believe it was connected to a letter R on the soleniod and a puple or black wire was connected to the letter S all my wiring is original on my Firebird? Is it possible that when the starter went bad it took out my coil? I took one of the plug wires to see if there was spark but there was not any but it was daylight so I really dont know if it was there or not? If not the coil what else could it be? And how do you check to see if the coil is getting any voltage or current/

The yellow wire goes back to the coil to boost the distributor voltage during the starting sequence to a full 12 volts. After starting the distributor voltage runs through the resistance wire dropping it down a few volts. You can hook it up and see if it makes a difference.

I can't hook it up I don't have the 3rd terminal on the replacement solenoid/starter to do it I just have the pos. battery connection terminal and the terminal with the letter S on it which I have the black or maybe it is purple colored wire hooked to it?

Yes it will be the purple wire on the "S" terminal. If you haven't already, go to Vikki's site and get the wiring diagrams for the 67. BTW, you also may want to check out the 68 for the area around the starter as it is a little clearer. If you are concerned that this is causing your starting problems you can always take a jumper over from the battey while someone is cranking. Don't leave on to long or you could burn up your coil (if you have the original point setup). Are you running points or petronix?

I have points in the car. I am wondering if like I said in one of my posts that when the first starter went bad it could have fried the coil? I have no problem getting the car to turn over it just will not start and it ran fine before I installed the new starter. Thanks Dan

I was tucking my wiring away tonight, and I could NOT for the life of me remember what I ran this yellow wire to the starter for. Thanks Hokie! I have one sad wire hanging over my fender teasing my swiss cheese brain.

I know, I need to stop pulling up these OLD posts, but, i've found so much great stuff on here, that I have not been able to find anywhere else, I like to say thanks!
