87 grand wagoneer battery issues

I have an 87 wagoneer, the vehicle has been sitting for a few weeks bc my transmission is bad, well every so often I would start it, than last week the battery was completely dead like wouldn't charge anymore so I bought a new one, well it's been sitting a week and my battery has mysteriously died, there are no lights or anything on in it so i dont know what it could possibly be.

It's a Chrysler transmission, the 727. But you should be able to get the right parts by asking for parts for the right year and model of Jeep.

Do you know how to use a multimeter? Measure the current between the battery and one of the disconnected cables. Then start pulling fuses one by one until the current drain stops. This broadly isolates the problem to a few circuits. The wiring diagram can be found at www.oljeep.com or in your TSM.

To identify it look online. You'll be able to tell by the pan and some other tell tale signs.

It's possible you got a defective brand new battery. I've had that happen before.

I took my battery out and put it on a charger, when i hooked it back up to my car as soon as my negative touched the spoke my car started itself without my keys even in it. Than after about 30 seconds it shut itself off. I than put My key in it and it started fine but my starter makes a weird noise now when it starts.

Your ignition solenoid might be sticking.

Lots of sparks when you hooked up the battery? My Cherokee chief with a i6 did that to the PO, turned out being the starter solenoid!!

Wouldn't it need to be the ignition solenoid? He said it ran so it need power to the coil.

That's what I was thinking lol! He said mine just stuck on crank and he had to in hook the battery, this sounds like old electronics

There wasn't a lot of sparks. But it did spark and like pop than it cranked itself over and turned on, hasn't done anything sketchy since charging my battery but its only been an hour or so.
