Battery discharge - maybe alternator pulley?
By holliday - 11/28/2002 10:29:23 AM; IP 205.188.208.168
My alternator has a 5" diameter pulley wheel on it. The battery will not stay charged. I'm thinking this large of pulley will slow down the rpm of the alternator. Would this cause a charging problem or should the alternator still put out enough juice to keep the battery at full charge?
Some other info, the car is a GT500 with all new wiring under the hood, new alternator (55 amp that I had tested before I left the store to make sure it is good) new voltage regulator (non resistor) and the ground to the engine block from the alternator and battery looks good and the ground to the voltage regulator off the headlight wiring harness looks good. The belts are new and seem tight enough. The only older part is the original type Autolite battery. Any thoughts would be appreciated!
