i have been having them about a year took them out of my jeep because breaking stuff this truck is just a toy to play with
dom rebuilt the alt for the jeep with a exturnal regulator but now it is charging at 18volts at idle and goes up to 20+ if you rev a little so waiting to here back from him
i am running dual alt the second alt is just for the batteries in the rear
guess with christmas his shop is closed
