I have a 1962 Pontiac with a small block Chevy. I recently changed the powerglide to a th350. I had to change the flexplate and starter as well. My question is, on the old starter there was three wires(terminals), a 12 ga. black which connects to the battery + terminal, a 16 ga. violet which I believe goes to the safety switch then to the ignition switch, and a 20 ga. white wire which connected to the third terminal on the old starter, and at the end of that white wire, there was a 20 ga. green wire that went to the + terminal on the coil. On the "new" starter, which comes from a 1977 Chevy, there are only two terminals, one for the 12 ga. black wire and the other one seems to be for the violet wire, based on the position of the terminal on the solenoid. What do I do with the white wire, just simply run it up to the + on the coil?

are you still using a points dist???

the second wire (R or I terminal) from the old starter to the coil was to feed full batt V to the coil while the starter is cranking to help the engine start....

at cranking speed, a points ign only puts 6-9V to the coil thru the "run" wire due to a resistor or resistor wire...

with only 6-9 volts while cranking a motor can be a pia to start (cold or hot)

No, I'm using an HEI with an MSD6A. Are you saying that I can connect the white wire directly to the + on the coil?

Doc,

Can you please help me out on this one?

I forgot to mention, I'm converting over from a generator to an alternator.

because you have a HEI/MSD ign you don't need the 3rd terminal connection white wire from the starter to the coil.....

your ign doesn't use a resistor, the coil receives full batt volts so it doesn't need a "points ign voltage boost white wire" while cranking to help start the motor

connect the violet wire to the starter....should start fine

hope that's clear enough

Doc here,

FIRST, as always,

Refer to your MSD instructions for a ballast resistor..Some require them to protect the module, some do not..verify yours..

NEXT , verify with a METER that the Coil Plus wire does not lose power in "Start" altogether..Some Vintage Ignition switches DID..If that is the case , you'll need a secondary regardless of HEI or not...(not a lot of these around, but show up from time to time) there is a Very simple fix for that should it be needed.

The Battery cable, and 10 gauge black wire, and The alternator output (plus ALL fuse links) should go to the big terminal on the starter solenoid,

The purple wire to the "S" terminal , (closest one to the block)

The white wire (if like 99% of most GM HEI) will not be used for this application.
