My battery keeps draining overnight. I disconnected the negative from the battery last night. But today the vehicle started but stalled five times while driving. Can you help me?

Hi,

An electrical draw can be caused by many things. The only way to determine the cause is by checking one component at a time to see which component (when disconnected) stops the draw.

The first thing I need you to do is follow the link below. It explains the most common causes of a battery drain.

Let me know if anything helps with the link. If it doesn't, then we will need to get a voltmeter and connect it between the negative battery terminal and post on the battery to see which fuse will stop the draw.

Let me know if that helps or if you have questions.

Take care,

Joe
