O.K. History: Just put in a 350 SBC bored .060 over, heads redone, new valve springs, lifters, cam etc. It is carbed and has HEI. Drove jimmy in garage swapped motors and some parts put back together and slow cranking starter. I have put 3 starters on and still same problem. I havent even had it running yet. Ran some tests with voltmeter: Negative lead on voltmeter to negative battery post and positive on meter to S terminal on solenoid. A little over 9 volts when cranking. Negative on meter to engine (ground) and positive on meter to solenoid strap on starter motor. 12 volts when cranking. Negative on meter to negative battery post and positive meter lead to starter body. less than one volt when cranking. battery is around 13 volts before and after tests. Positive battery cable at starter is battery voltage 13 or so battery wire at dizzy cap is 12 volts wires replaced that come out of fuse block and go to dizzy and starter fuses replaced in fusible links and checked with voltmeter OK Distributor gone thru and all working properly many things replaced. Any ideas???? Thanks I have checked the wiring diagrams and all seems proper. Does anybody have any leads from the negative cable that go anywhere?? I do have grounds from body to frame, frame to motor.
