Battery keeps dying in '88 jeep cherokee

If anybody knows anything about jeeps with electrical issues, I could use their help. No lights or anything are left on. It keeps dying after I jump it and let it run, it'll run fine but if I let it sit when it's off then the battery is completely dead. I have a brand new battery and just put in a new alternator... Any ideas would help!

There has to be something drawing current while its shut off.. not sure if this is the proper way to do it but here's what I would do. With a voltmeter or test light test for voltage in your fuse panel and see if you get anything. I don't think anything should be receiving power at the fuse box while its off.

Search the internet for "troubleshooting parasitic drain".

Here is one basic link, but I'm sure you can find some others.

Without "data", all you have is an opinion!

on my 88 there are 3 places that get constant power when the truck is off, they vary with power as well but arent meant to have fuses except on high end models (pwr locks etc). use a test light and see if there are any useless fuses in there. people try to solve other electrical problems by sticking in more fuses and hoping but it often causes this problem.
try leads into doors if you have power windows or locks. if you have a 4spd like i do my slave cylinder leaks just enough not to notice but it dripps onto fusebox, see if your fusebox is dry and not getting hot to the touch.
