Low idle voltage... High output alternator
I finally got a change to test my charging system after this round of winter mods.
Engine at operating temp with lights, fans on, radio, etc on I am getting 11 volts at idle...
J2 Fabrication 240 amp alternator
Big 3 "0" gauge wiring upgrade
Raptor e-fans (63 amps)
Two aux fans on my condenser (9.6 amps)
Taurus smog pump (15 amps)
Two Walbro 465 pumps (28 amps)
2.25" alternator pulley
750 idle rpm
Going to datalog with several different idle rpms once I get some revisions from Korn.
Suggestions? Afraid of overspinning the alternator.
