My 96 XJ just started killing my battery when not driven for a few days. I found that the is a power draw running all the time and I can make it stop when I pull a 20A fuse under the hood. It appears to be fuse F24 on the PDC (position 3/4 on section A of the PDC), but I cannot figure out what it goes to, other than making my radio and dome light not work when the fuse is removed. I have the FSM and I can see the fuse in the diagram, but it does not reference what it does or what it goes to. How can they have a FSM that does not list what this fuse does? Cross referencing other year diagrams and I think it might be for the fog lights (I don't have a factory fog light switch, let alone fog lights). It is really getting annoying having to pop the hood to put the fuse in to have a radio and pulling the fuse when I park it.

I am not running a stock stereo (Sony head unit, 4x50 Fosgate amp and 4 Fosgate speakers). I disconnected my Fosgate amp to make sure it was not staying on and the draw remains. I have disconnected anything that is not factory and still dead battery. I purchased a new Optima yellow top, but do not want to kill it too. The PO has a rats nest of wires under the steering wheel

Can anyone help???

Here is the diagram from the FSM to reference which fuse

 

you need to search 6 ways in the fsm, its probably hidden in there somewhere.
ill do a quik look in haynes, fsm wears me out!

haynes no help

 

I think I figured it out. I pulled the harness plug from the back of the radio and the draw goes away. I don't get how a radio that works could be causing a draw like this? Could the radio have a short in it from me barreling down dirt roads at 40mph, but still work fine?

 

fsm,,,spare! maybe po used inn rats nest

 

No comprende

 

the factory service manual shows it as a spare,,,meaning unused by the factory...

its possible that the previous owner used it ,,somewhere??

 

Note from DJ
I think your Pacific Cost Manual is wrong it shows the fuse in question is a 15 AMP fuse; but your photo shows it being a 20 AMP fuse.
The photo that I’m including may be more accurate.
What is the model number of your Sony Radio?

HELP, 1996 Cherokee - Stereo Color Codes
http://www.jeepforum.com/forum/f20/h...-codes-181077/
OP by telescopic
I have a 1996 Jeep Cherokee Country 4-door, and the factory stereo wiring harness has been cut off. I know that pink is 12+ constant, and a couple others, but the speaker wires are going to be difficult to figure out. I also tried the 1991 model color codes, but they're not right. Does anyone know the color codes for this year? That would be a big help. Thanks!

Well, I went ahead and figured out all the colors on my own. Here they are, from a 1996 Cherokee Country 4-door.

12+ constant: pink
12+ switched: violet/white
illumination switched: orange/black
illumination switched: light blue/red
Both illuminations appear to do the same thing (voltage goes down as the instrument lights dim), and indeed there is only 4 ohms between them. So they seem to be connected together somewhere.
ground: black

left front+: green
left front-: brown/red
right front+: violet
right front-: blue/red
right rear+: blue/white
right rear-: blue/orange

unknowns:
brown/yellow
brown/blue
It appears that the left rear speaker has faulty wiring somewhere. The above colors are likely for it.
