Describe the procedure for checking for parasitic battery drains.

What will be an ideal response?


To measure the drain on the battery, use an in-line digital ammeter rated at 10 Amps with the capability of measuring in milliamps. Then connect a jumper wire fitted with a 10-amp circuit breaker or fuse between the negative battery cable and the negative battery post. Doing this will maintain the memories in the vehicle. Then disconnect the negative cable from the battery. Be careful not to disconnect the jumper wire while doing this. Connect the in-line ammeter between the end of the negative cable and the battery’s negative post. Once the meter is in place, remove the jumper wire. Observe the current reading on the meter.
