Since I have bought my truck used I have always had a constant voltage of 14 Volts, whether I was idling or driving.
Friday I noticed that my dash seemed a bit dim, but no charging warning light. I later noticed that my sunpro guage show 12Volts.
Long story short
I bought a rebuilt alternator.
Now my voltage is 13-13.8Volts at idle after few hours of driving. The voltage changes depending on my driving speed. I was worried about this so I went to PepBoys (bought re manufactured one from there) for a Alternator test. I thought maybe for some reason it was bad. So the tech hooked it up and it passed :Regulator Volts At idle. 13.96 Peak current 112.3 Amps and 13.7volts with AC on max, high beams on and fog lights on at idle.
The tech said as far as he knows the voltage should not have been constant 14volts. The regulator must have been bad and I risked overcharging.
I performed Fords load test with then engine at 2000rpm and everything on at full blast and the voltage will go up with the demand and engine speed to just about 13.9 volts. The lowest voltage I have seen is just is 13volts at idle. Nothing dimmed or flickered. The manual states voltage should be 13-14 volts, so looks like all is well and my regulator is doing its job and regulating, unlike in my old alternator.
Guess I have to get used to watching the volts go up and down with speed and load.
What sucks the most is I had to shell out $150 bucks when I have a perfectly good extended warranty. The dealer and warranty company are not open on weekends.
I have read plenty of times here that people are getting 14volts at idle.
I will see how this replacement performs.
ANYONE HAVE THE SAME RESULTS AS I AM AND NOT A CONSTANT 14VOLTS???
