Ford Ranger keep draining the battery. Ive checked the alternator which is fine. Seems like something is staying on and draining the battery each night. Where should I start looking and how should I test it. Thanks'

The door ajar light was staying on, but I think I have fixed that. Battery still is draining down and I just put a new battery in it about two days ago.

Im going to try the parasitic draw test tomorrow evening. I put a new belt on and it was fine, not since the battery started draining it has started to squeal a lot.

If the belt is squealing did you check the belt tenisor?

I replaced the pulley for the tensioner, should I replace it all?

The pulley only spins the arm is spring loaded thats what keeps the belt tight. Does the belt still squeal?

Needed a new water pump and belt tensioner, so that is fixed. Now the battery is still draining, and the turn signals have quit working. I have yet to find anything that is draining the battery.

Yes, I found that it may be the door switch. The extended door on the drivers side does not latch. Would that cause it to drain the battery.
