Does anybody know what the "JB Power" fuse in the '02 Jeep Liberty power distribution center (underhood fuse box) is for?
My problem is that my charging system seems to not be working as it should. I first thought it as a bad battery, then a bad alternator, and replaced both. My Liberty seems to discharge the battery. When I attempt to drive the Liberty, my battery light turns on and I'm afraid it will run down all power as it did with first battery. I'm not taking a chance with the second one.
My question about the JB Power fuse comes due to some diagnostics I have done with a test light. When I connect a test light to the Neg. battery cable ( cable is disconnected ) and touch the test light to the terminal, the test light goes out when that fuse is removed signifying that this component has a short it in.
On the downside, my warranty expired 1,800 miles ago!!
I would appreciate any ideas.
