In this episode of The Trainer, Motor Age Technical Editor, Brandon Steckler discusses the importance of locating the root cause of battery and alternator failures. As we all know, battery and alternator failures are common on virtually all makes and models.

Many don’t realize that the electronics within the alternator take the brunt of the damage when an underlying charging circuit fault exists. The alternator must work extra hard to charge the battery to compensate for these circuit faults. As a result, the temperature of the alternator's electronic components gets too high and causes damage. This results in repeat alternator failures that seem to go on and on. Usually, the alternator is labeled as an inferior component and is replaced under warranty. The problem is that the true underlying fault is not always located, and the process repeats itself.

Follow Brandon as he uses the Automotive Test Solutions eScopeELITE4 and a current probe to evaluate the charging system circuit dynamically. This quick 3-minute test locates underlying voltage drops in the battery charging circuit, can be applied to all vehicles using an alternator, and requires no disassembly to perform.
