Question '69 Camaro Ignition Start Wire

All,

On a ’69 Camaro small block V8 electrical system there is a yellow wire that goes from the “+” terminal of the ignition coil down to the “R” terminal of the starter solenoid. What keeps that wire from feeding +12 volts from the ignition switch to the starter solenoid and starter motor after the car has started? It looks like on a wiring diagram that the “R” terminal and the “M” terminal are connected internally in the starter solenoid, but maybe that’s not the case. I think the purpose of that wire is to feed full +12 volt voltage to the ignition coil and bypass the resistor until the car starts, but I could be wrong. Thanks.

Doug

Re: '69 Camaro Ignition Start Wire

Doug, you are correct. The yellow wire supplies 12 volts to the coil when the ignition switch is in the start position. Then after the engine starts and the key is in the on position, the current flows through a different wire leading to the resistor wire to the coil.

Question Re: '69 Camaro Ignition Start Wire

OK, but after the car is started, what keeps voltage from backfeeding from the ignition coil down to the starter solenoid and putting voltage on the starter motor? Thanks.

Re: '69 Camaro Ignition Start Wire

The yellow wire is an independant normally open contact on the solenoid relay.
Once you release the key from start, the relay opens and opens both this connection and the starter motor connection

Re: '69 Camaro Ignition Start Wire

Jim, I guess it's a combination between the Relay switch and the ignition switch that breaks the contact. Once the ignition switch is back to the on position, the relay is no longer energized? Is this correct?

Re: '69 Camaro Ignition Start Wire

That's correct - the "R" terminal on the solenoid is only connected to power when the solenoid plunger is fully engaged/extended and the starter is cranking; when you release the key, the solenoid plunger retracts, and the contact with the "R" terminal stud is broken. You can put power on the yellow wire under that condition and it won't do anything.
