1989 cherokee pioneer 4.0 automatic.

I've pulled out every fuse that I know of and its still drawing current.I've tried disconnecting the alternator. I've had the battery tested its good. You can see a spark when you go to connect the positive cable.

What else could it be?

 

If you have pulled every fuse and it still does it that narows it down to the cable from the batterey to the fuse box. I THINK

 

You may have a faulty ground somewhere....I don't know though...electrical is not my forte.

 

replace every conection between battery and fuse box (upgrade to 4 gage) replace down to starter also. Im 98 percent sure that will solve (unless your battery is bad)

 

Okay thanks will do.

 

If its a problem with the wires to the fuse box wouldn't it be a huge power drain? Mines not that big I can leave the battery connected while I'm at work and after eight hours it starts up. Its just like something on that shouldn't be on.

 

your alternator is working like it should?

 

Yeah I had it tested when I had the battery tested.

 

You might check the door jam switches. Do you the dome lights work. You might have left them on. Just thinking out loud.

 

Dome lights work. The switch on the drivers door doesn't turn it on though.

 

How about the under hood light staying on after the hood is closed? Do you have a stock stereo?

 

The hood light has never worked. I could try unhooking it I guess to make sure it doesn't turn on when I shut the hood. I have an after market cd player. It turns off when I turn the key off though. I have no amp or speakers. Could it be the starter?

 

do you have a alarm or keyless start?

 

You could consider buying one of these:-

At $36 including shipping, it might save you a lot of grief.

With a 40A DC current range – it should be able to measure down to 0.1A, allowing you to trace the wire through which the current is flowing. Cheaper current clamps are available – but importantly this one measures DC current (via the clamp), meaning that you don’t need to disconnect wires.
