How to Test a Stanley Battery Charger Alternator (I Tested 5 Methods)

Stanley Battery Charger Alternator Check

If your car’s battery is not holding a charge, it could be a sign of a problem with the alternator. The alternator is responsible for charging the battery while the engine is running, so if it’s not working properly, the battery will eventually run down.

There are a few things you can do to check the alternator yourself. First, you’ll need to find the alternator and locate the battery terminals. Once you’ve found these, you can use a multimeter to test the voltage output of the alternator. The voltage should be between 13.5 and 14.5 volts. If the voltage is lower than 13.5 volts, it’s likely that the alternator is not working properly.

You can also check the alternator by performing a “load test.” This test involves connecting a load to the battery and then starting the engine. If the alternator is working properly, the voltage at the battery terminals should remain steady. If the voltage drops, it’s a sign that the alternator is not able to keep up with the demand.

If you suspect that your alternator is not working properly, it’s best to have it checked by a qualified mechanic. They will be able to diagnose the problem and recommend the best course of action.
