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.

I have seen the A/C compressor clutch relay stick on which can drain the battery here is the location so you can check it out.

This guide can help as well.

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.
