Fault in Power Distrobution Center

I have an amp draw on the 30 amp fuse circuit on the bottom row (closest to the fender) on my '96. This, I believe is what is causing the GEN light to be on consistantly. There is only one 30 amp fuse on the bottom row, so I need to know what accessories are run off of this circuit.

I know that I have amp draw because I put a voltage indicator light between the terminal and the cable of the negative side of the battery. Ideally, this shouldn't light up at all, as its a ground. It does however light up and when I pull this fuse the light goes away. This tells me that I have an amp draw on this circuit that is sapping my battery.

When I remove this fuse and try to start the engine, there is no ignition happening, however the aux fan comes on and stays on until I stop trying to crank it.

Right now, I can't really drive my xj because my batt dies on me all the time. So please let me know what accessories run on this circuit and I'll try to diagnose this as best as I can. Thanks for your help.

Check your inittab.







I'm not sure that you are diagnosing this correctly.
If I have it correct, that fuse supplies power to the ECU, and the ABS system.

Which would explain the no-start.

Best way to diagnose this type of problem is with a multimeter(current meter)--see post below.



Does the battery not die if you pull the fuse?

no, the battery doesn't die, it just doesn't lose its charge

what is on that circuit? I'm thinking that one of the accessories is grounding out or short circuiting.

I'll look at the ammeter thing as well
