2000 Toyota Camry XLE V6 voltage regulator failed test. In 24 hours I have put 2 new alternators on the car and this still fails. I can see the remote possibility of 1 bad out of the box alternator but not 2.All fuses are good.Any ideas?
It can happen but I would double check all your battery connections. Pay close attention to where the negative battery cable bolts to the frame and motor
The stock alternator only failed the voltage regulator too so this is 3 in a row in less than 24 hours? Grounds look good.
Hmmm. Sure sounds fishy. All wire harnesses look good too?(not hacked up) any one done any work on car recently?
Other than the alternator replacement no recent work. All harnesses look good basically in factory condition plus 14 years of grime. Battery 2 years old.
Does anyone have a wiring diagram of the wires on the alternator. There are 4 wires total. Large black bolt on White Yellow Red with Blue stripe
