I have been having starting problems with my 76 Palm Beach.
On occasions it starts up immediately but other times I have to crank and crank and than give it an extra boost to get it to fire over.
I took readings with the engine running on the isolator the top post was at 13.1, middle post 14.0, and bottom post 13.2. With the engine off top post 12.2, middle post slowly drained down from 12volts to .5volts, bottom post at 10.7. I checked battery voltage and it was at 12.1. Would these voltage reading be an indication of a bad isolator, bad alternator, bad battery or combination of all three?
