Testing a Failing Starter Generator

A starter generator is a crucial component in any vehicle that uses an internal combustion engine. It is responsible for providing the spark of energy needed to kickstart the engine and keep it running. When it fails, it can cause major problems and render a vehicle unusable. To ensure a starter generator is functioning correctly, it must be tested periodically.

When testing a failing starter generator, the first step is to check the battery voltage with a multimeter. If the voltage reading is too low, then it can indicate that there is an issue with either the battery or the alternator and these components should be checked and replaced if needed. If the voltage reading is normal, then proceed to test the starter generator itself.
