My altinator show good on machine but when i
hook to car tester says voltage regulator fail but all
the rest comes back good how do i repair
I have a feeking that you have a bad wire from the alternator to the regulator...
I agree with CometGuy, check the wiring first, but if that checks good then the charging system is computer controlled on this vehicle, so you may have a fault there, you may not get a check engine light even though it is not operating.
