what are the voltages??
Roy
The alt is steaddy at 14 volts, until the hard excelleration then it dorops to just below 12 volts. I just noticed that when I touch my turn signals the volt meter twiches, and when I roll my power windows down in the back the volts drop down to about 12 volts. This is the 3rd alt in 6 months.
also, I just had they neg battery terminal replaced. They say the alt is fine because there is a technical bulletin that says it will drop, but it does all this other stuff that tells me otherwise. Seems to be very littel out there on Troopers.
no, it is not normal for this to drop to 12.
first, check the belt tension. it has nothing to do with troopers but has to do with basic electric in charging systems.
start with basics. check the belt tension
