Re: Accessories stay on; Battery drains
you have some sort of battery drain. you can check the ing. switch if
it's bad
it's under the colum covers .not at the base. the saginaw steering colums
were dropped in 94
i would be checking out all the grounds real good when grounds are loose
or poor, elcectric relays make alot of noise and battery power looks for
grounds backtracking thru wires looking for the ground points and things
get dim
the main ones are on the engine block by the dipstick
the dash harness has some on the lt side under the kick panel and one is
under the drivers seat
you can check for a draw using a test lite and pulling fuses

When you do get this fixed, another thing that helped me with
long-term accessory drain is getting a deep-cycle battery (I got an
Optima). It works great for things like leaving your GPS/radio on
while parked and shut off (so as not to lose satellites, or to use
your Jeep as the campout stereo system), etc. Gives you lots of
freedom, and also protects you against cycle drain like alarm systems
exact on your battery.
Good luck,

As for everything staying on. I'd have to suspect the ignition switch.
Maybe at one point it overloaded and some of the contacts are now
burnt on.
As for the unknown draw killing the battery
I would disconnect the positive cable from the battery and put an ohm
meter between the cable and vehicle ground.
The reading should be in K ohms (thousands). I'd bet yours will be in
the 100's if not 10's of ohms. Simple ohms law reveals the actual draw
on the battery. Volts divided by resistance = current in amps
Once you've checked the reading, start pulling fuses. A couple extra
clip leads helps get the meter under the dash so you can watch it as
you proceed.
When the reading jumps into the K ohm range, you've probably found the
culprit.
On mine it was a short in the power antenna which was fixed by simply
leaving the fuse out.
Hope that helps

As for everything staying on. I'd have to suspect the ignition switch.
Maybe at one point it overloaded and some of the contacts are now
burnt on.
As for the unknown draw killing the battery
I would disconnect the positive cable from the battery and put an ohm
meter between the cable and vehicle ground.
