Why is my alternator putting out 17 volts?

Why is my alternator putting out 17 volts? It may be that the regulator is packing up and the alternator is going to max. unregulated output because of a bad battery output voltage (alternator input) connection between the battery and the alternator.

When does a GM alternator need to be replaced?

A GM alternator that is producing too much voltage must be replaced. When a car does not start or the lights are dim, it may be because the voltage output has dropped lower than 13.5 volts. When this happens, the battery is not being charged, and the electrical systems of the vehicle will fail.

Can a racing alternator be installed in a stock car?

What happens when an alternator does not work?

The alternator becomes overloaded and these systems stop working. This results in a car that stops and does not start. When the alternator doesn’t work, the energy to power these things comes from the battery, soon worn down from lack of charging. It is pretty simple to measure the output of a GM alternator.

What causes an alternator to overcharge on a stock car?

When the wrong alternator has been installed in a stock vehicle or if the pulley has undersized dimensions (causing extra alternator rotation), the charging supply will be higher than the demand and cause an overcharged state.
