If your block is properly grounded then the starter solenoid mounted to the side of the Chevy starter should be grounded enough to function. However, a dedicated ground is a good idea.

Are you using just the solenoid on the starter or are you using a double solenoid setup (used for solving the Chevy hot start problem)? Either should work, but the wiring would be a bit different.

Double check that you have wire from the ignition switch connected to the 'S' terminal not the 'R' terminal.

After that I would disconnect it and hook it up to a multimeter to see if it is getting power when the key is in start position.

They should be labeled if you look closely, but the small terminal closer to the block should be the 'S' terminal.

Here is a picture from a Chevy forum.

I would go ahead disconnect the 'S' wire and test with a voltmeter to see if it is getting power when the key is in the start position.

OK i was able to get starter to spin and engage. But the rear breaks and reverse are always on, the "main" power wire runs to the large "power" post on starter. Obviously without it vehicle doesn't start. Previous own splice a smaller 12 to 8 g wire would that be the ground or would that be the wire to tie into the smaller post to bottom right of solenoid in my pic? Sorry new at wiring

I'm afraid I don't quite understand what you are asking.

When setting up the Chevy starter with a dual solenoid system the 'S' terminal is jumpered to the 'battery' terminal with a short piece of wire. Does that sound like the wire you are asking about? If it does, you do not need it.

The starter in your picture appears to have all the necessary connections (the ignition switch wire connected to the small 'S' terminal and the positive battery wire connected to the large 'battery' terminal). The only thing missing is a proper ground. The starter was designed to be able to ground through the engine block. However, connecting a dedicated ground wire directly from the negative battery terminal to the case of the starter can eliminate grounding problems. The long bolt sticking out of the main starter motor housing (in your picture) would be an excellent place to connect a dedicated ground. Ideally you would want to use the same gauge cable for the ground as the battery cable, but most don't have one at all.

Here is a picture of Fatman's excellent starter set up with a dedicated ground. (His is also set up for dual solenoids. Your red wire should run to the ignition switch not jumper the two terminals.)

I appreciate your help. I have the started mount and spinning. But the rear break lights are now constantly on with and without key in ignition. I'll post pics of starter wiring (if I can) and the lights if need be.

Oh... that is interesting....

Is it the brake (red) light or the reverse (white) light?
