Notice the white/orange/red/ resistance wire from the FB to the starter. Then see the wire to the ignition coil ties into it. You get 12 volts while starting and 9 volts during normal running. That's why you need to replace that wire or run a new one to the HEI distributor.

I can identify the other wires if you need me too.

BINGO..............I got it. Comedy of errors surrounding that Resistance wire. My wife says it's pink BTW. Doesn't matter.

I didn't realize until today that resistance wire had a butt connector with a yellow wire to the starter. I've always "known" it to be the yellow wire to the starter. So every time someone mentioned "yellow starter and coil", well, between not having a coil and being an amateur, have to say, I gots confused.

I can't tell you how many times I've handled the starter, only to reconnect the "yellow" resistance wire resisting nothing.

Thank you for clearing things UP.
