Sounds about right Posted by Ari [Email] ![]() ![]() In Reply to: Re: I'll have to dig out schematics, Jim, Thu, 28 Oct 2004 13:43:24 Members do not see ads below this line. - Help Keep This Site Online - Signup |
The Ignition switch relay drives the "+54" power bus. According to the manual, that bus is powered ONLY when the key is in the ON position. It is not powered in the Start position, so what you're seeing is exactly right. The lights should go out in the Start position.
I'm not sure what the ignition signal relay is - I think this might be the Ignition Signal Amplifier. This would drive ignition, but wouldn't affect the starter motor.
With an automatic, the path for current to the starter motor is pretty simple. Turn the key to START. Current flows through the interlock switch, which is closed in Park and Neutral. It then flows to the solenoid contact on the starter. That's it. No other relays, switches, or other items. So I would put a meter on the wire to the solenoid. If you don't get voltage to it when you turn the key to START, then the problem is the transmission interlock. If you do get voltage to the solenoid, then I'd suspect the solenoid. Usually you get a click from the soleniod at least.
But the ignition lock relay isn't it.
