Re: Battery draining

A blown diode will cause the battery to drain.

First, take you volt meter and put the positive lead on the positive post and touch around the top of the battery with the negative lead to see if you have any drain across the top in dirt/moisture. If the battery top is dirty this can happen. I've seen one that drained in a little over two hours as it had over a 9 volt drain across the top of the battery.
