Testing for parasitic draw

In some cases, it can be severe enough to deplete your fully charged battery overnight. Although you can test any circuit for a parasitic draw, this is how it works for a draw on an alternator, and all you need is a digital multimeter. Fully charge the battery. For accurate results and enough time to finish testing, a full battery is recommended.

They are only accurate down to an AMP or two, which is much higher than any draw you would be looking to measure. AMP clamps are good for high current measurement - like a starter draw or alternator charging rate.
