Solenoid Wiring Hook-up - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I took out my starter to change my solenoid (intermittent problems). I noticed there were 3 wiring locations with 2 attached (battery and something else). There was a 3rd wire hanging down with no connecter end (and not connected). Any thoughts about what this is? Does it need to be attached?

If you have an HEI distributor and the wire is yellow you don't need it....

Not HEI. Original. Apparently the other is the switch. Not sure as to the other wire.

Wire from the neutral start switch to the "S" terminal on the solenoid is a 10 or 12 Ga purple wire. The wire from the coil to the "R" terminal on the solenoid is a small yellow wire. I don't remember what Ga it is.

It's odd because I don't think it was connected. It definitely doesn't have a connector and is a bit shorter. Will is start with just the switch and power?

Had it been starting OK before you removed the starter? With a points distributor the Yellow wire from the solenoid (R) post supplies a full 12 volts to the coil when the engine is cranking over. After it starts the voltage to the coil drops to 6-8 volts through the resistor wire.

Like doc said. The points wire is closet to the frame rail when the starter is installed. The ign switch is closest to the block.

It must be the points wire. It was starting fine (except for the solenoid not kicking out fully.
