iagree His problem is not the starter. It could be a poor connection, poor wires, poor battery or dying voltage regulator. On my 440 when the regulator went bad it would start up great when cold but slow when hot just like the op said his does. I also thought the problem was heat, headers, and a junkyard mini starter. New VR and problem solved. BTW, problem did not show up on the ammeter.


I find it very unlikely a bad VR would cause this. During cranking, the alternator (and hence VR) has little to do with anything....its 99% battery voltage until the motor starts. If the VR was bad the alternator output may be out of whack (which it isn't 13.8V hot). I also don't see if a VR was bad , how it wouldn't show up on the ammeter. shruggy Even so, I had another VR on this car for a time and the issue was still present.

I would find it more likely to be a bad/undersized cable then a charging system issue. The battery is pretty much new and has given me no indications on being bad.

I don't mind stepping up to a heavier duty cable but nobody seems to make them for my car and I don't want a generic cable spliced in all over.


The ammeter reads current, not voltage. Voltage can drop even if current stays high. Without enough of both when running, your battery won't fully charge. Add to that the engine is easier to turn over cold than when hot. Also, like stated by others, a bad ground, poor connection or corroded wires can cut your voltage at the battery or starter.
