zipfactor well i thought id try taking a shim out (starter is shimmed on outboard bolt) and fire it up. Tried that and no more whinning noise. Thanks for the help rrmccabe.

You say you know it disengages when you are cranking it? It shouldnt disengage when you crank it. It should only disengage after you stop cranking it. And since you dont have the distributor power running on it how would you know?

Try doing all this with your alternator hooked up. Your wiring is obviously hosed.

rrmccabe Zip,

I have no idea what you are talking about now. You have lost me.

I thought the "whine" was when the vehicle was running?

Now it sounds like it is doing it when you are cranking. Which is it?

Unhooking the battery wire to the distributor cant possibly do anything to effect if the starter whines or not during cranking.

I just looked at your previous post and you said "I started it without power to the distributor and it disengages".

How do you know if disengages? The car cant even start with the distributor wire unhooked.

zipfactor wait a second, i think we got confused. I unhooked the power wire to the distributor and spun the engine over and my starter didnt whine, I didnt unplug any other wires. were you thinking i unplugged some other wire?
08-27-2005 08:19 PM
zipfactor I followed the wiring diagram out of the haynes book, but maybe that is not right. I'll try unhooking the alternator and see if that affects my starter issue. How are the wires from the alternator connected on a 1976 Pontiac Trans Am?
08-27-2005 07:37 PM
rrmccabe So what happens when you unhook the alternator?

Sounds like your wiring is wrong and the alternator is backfeeding the solenoid circuit and keeping it cranking

zipfactor yeah i have the small 12 gauge wire going to the "s" terminal, and the positive battery wire going to the big post on the starter. I'm not sure how whether the distributor wire being hooked up or not affects if the starter keeps spinning, but im not the most knowledgable about car wiring either. What i did the other day was changed some of the underhood wiring. I was checking all my wiring out to make sure it was good (no frayed wires , etc.) and noticed that a wire from the alternator, the sensing wire, was hooked up to a connector. According to the wire diagram i have (out of a haynes manual) it shows that the sensing wire should be hooked up to one of the main feeds to the alternator. So i hooked it up to that. *shrugs* so you dont think its a shimming issue then? thanks for all your responses

Nope, I dont think so.

The wire that goes to the "s" (inside small terminal) on the starter. Is it easy to get disconnected while the vehicle is running?

You only have two wires going to the starter? The main battery cable and the smaller one going to the above mentioned terminal.

Keep in mind, you need to get this fixed asap. That starter is NOT going to last long. Don't run the engine long.

if you take a shim out, it will be to tight, add a shim

rrmccabe I thought you said it stopped when you disconnected the wire?

rrmccabe Well then it sounds like you are backfeeding the solenoid if your wiring is in fact holding it up.

Rich

zipfactor i just thought about it and realized maybe i have it shimmed too tight to the flywheel causing it to not disengage when it starts. I started it without power to the distributor and it disengages, but i think it doesnt when i go to start it with power to the distributor.
