A Simple Key For alternator repair shop Unveiled

Voltage regulator tests                  

Checking the alternator is a relatively uncomplicated process. Alternator charging voltage may be checked using a digital multimeter at the battery terminals. With a fully charged battery, alternator charging voltage ought to be about thirteen.
