To Those Who Dabble In The Dark Arts Of Auto Electric (Alternator Problems?)
I recently upgraded from a 140 amp alternator to a 220 amp unit. I've got twin electric fans, electric fuel pump, AC, etc. With the old alternator I was putting out just under 13 volts (per the AutoMeter gauge). This would dip to around or under 12 volts with the AC running and the headlights on. When I upgraded to the new alternator (one wire unit) I also went with a 0 gauge wire to the battery. When I fired it up it read just over 13 volts on the gauge. When a checked the input wire at the battery it read 14.4 volts. Am I missing something here? Where did the juice go? Any help from those who are in the know would be appreciated. Mike
