How To Troubleshoot An Alternator On A Tow Truck

When it comes to tow trucks, the alternator is an essential component. It provides electrical power to your truck while also charging the battery. If the alternator is failing, your truck may experience a variety of problems. Fortunately, troubleshooting an alternator on a tow truck is a straightforward task.

Signs of a Failing Alternator

One of the first signs of a failing alternator is the warning light on your dashboard. Other signs may include dimmed headlights, a dead battery, difficulty starting your truck, or a squealing sound coming from the engine.

Testing the Alternator

You can use a multimeter to test the alternator’s voltage output. A reading below 13.5 volts typically indicates a problem with the alternator.
