Hello all, The problem I'm having on starting is this sometimes when I crank the car over its like the battery is flat and there's hardly any reading on the volt gauge then all of a sudden the car will start and be fine. I just put new starter motor on and when I test the battery with a meter on tick over its about 13.7 volts and rises when you accelerate. Any ideas? P.s.I have a delco alternator but don't know what model? Cheers Paul.
