FJ40 that green thing
1996 KZJ78 Prado
I just recently had my alternator rebuilt by a pro on an 82 FJ45 with 2F engine. Truck starts and runs fine since replacement but I’m having concerns with the voltage.
I have a digital voltmeter on the dash I just installed and noticed when at idle it’s at 13-14 where it should be but as I drive and RPMs increase, the voltage increases to 15-16 which I think is too high? If I turn the lights and heater fan on it drops them back down to the 13.5-14 zone. Shouldn’t the volts level out at around 14.2 or so when driving for extended periods of time lights on or off? Anyone know why the volts are increasing over 14.3? Is this going to harm my wiring or alternator?
I did put a new voltage regulator as is suggested with a new alternator, I even put the old one in again to test and it does the same thing. I’m I making something out of nothing here or is something not right?
