92 F150 battery dies and no odometer

Ok, so I have a 92 150 5spd 5.0. Recently I changed the slave cylinder and for a week after the truck drove like a champ. One night the battery died. A quick jump and it was fine again for a day. Now, it'll only hold a decent charge for 1 hour. I pulled the positive terminal off with it running and it stayed running. I noticed the odometer is not displaying its mileage now too. I changed the battery to a newer and stronger one as well. Any guesses?

Well, odometer returned this morning. I'm just not sure why she keeps needing a jump

measure the draw on the battery and remove fuses one at a time. It's a quick and easy way to try and isolate the faulty circuit.

NEVER disconnect a running vehicle from its battery - you're lucky you didn't fry anything. Have the battery checked with a MidTronics tester, similar to this:

Any auto parts store can check the battery with a tester. If it checks out then there must be an electrical fault that drains the battery when its not being charged. A bigger battery Isn't going to help.
As mentioned, use a multimeter to measure the draw at the battery and pull the fuses one at a time until it goes down. When it goes down to normal the fuse you pulled will be for the faulty circuit. Then you can go from there.

92 has the older style alternator I believe. Mine shorted out in the regulator, had a 3-4A draw. I replaced it with the 3G alt.
