Battery keeps draining

[Trinidadwho]

My battery keeps draining (discharging), I recently bought a new battery about three months ago at Costco because the one that I had on my bronco died. About 3 weeks ago the new Costco battery died, and I went to return it and got a new one, and now its dead again. Any suggestions guys?

Hey Tdad,

Disconnect the positive terminal of the battery. Connect a test light between the battery post and the cable.

If the light is lit....even dim there is a drain. To isolate the circuit draining the battery, pull a fuse out one at a time and watch the light. When the light goes out that is the circuit that is causing the drain.

( often it is the glove box light!)

When you know the circuit that is drawing the current, you have to search down the offending component.

Good Luck
