Already checked that. With 2 different switches (both from old eagles) it still draws power. Slowly but surely. Everything in the car is disconnected now but that and it's sucking juice.

I have a feeling the old guy that had it before me has something wired in that's drawing power that shouldn't be. When I remove the switch or have it turned off its still drawing current.

The drain when I have the battery disconnected and leads attached to negative on the battery and the positive wire shows a .035v constant drain. It drops to 0 when a light switch or ignition is turned on.

Is anyone able to try what I'm doing on their good Eagle? Seeing and knowing if there is residual drain on a stock Eagle would go far in helping me.

Unhook the battery and put an ammeter between the battery post and the cable. If it shows a draw when everything is off, pull the fuses one at a time to try to narrow it down.
Drain is measured in amps not volts. An easier way for you may be to unhook one battery cable after dark. If there is a drain there will be a spark when you touch the cable to the post. Remove the fuses one by one until you don't get a spark. That will be the circuit that's at fault.

Maybe I shouldn't be out doing this when I have the shits. Can't think right when I have to poo every 15 minutes. ..

TMI, but I hear that! (diverticulosis) Just leave the battery unhooked. Does your door sag? If so, the door jam switch may be staying on (grounded inside)
AMC/Jeep gauges are for amusement only. Any correlation between them and reality is purely coincidental!

Have you found the drain or are you still on the toilet?

Well there is on mine. It's for the electric clock and radio memory. So if not using the car, I disconnect the battery.

There is on mine as well. So when not in use I leave it connected to a battery maintainer. Cheap and works like a charm.

Very good idea, keeps battery fresh all the time!    8)

Happy Eagle-ing   :eaglebig:

Off the toilet now lol.

I went from work to home, a quick 5 minute drive. Full voltage on the battery.


Hit home, car wouldn't restart.  :censored: battery dropped a volt in that time. I almost bet the alternator is bad.

Going to swap it out and see what happens. It seems totally random when it occurs.

Edit : the big thick wire from my alternator is busted in 2 places. Seems like it's separated quite bad on on side.

This now sounds like my concord. However my alt wire is good. Before i get into it, i carry a $500 battery booster that is awesome so when i get to my problem i get to it. I believe my solenoid is sh it. If it gets warm it will not start.

That problem is usually the starter . Needs a draw test
