Topic: Low Voltage and Gauge Problems

[JC93YJ]

The small 6awg wires goes to the front of the PDC while the 4awg goes to the starter.

How does it attach to the PDC? Does it have like a ring terminal or is it a soldered connection? Also, has anyone replaced these cables and knows of part numbers that would fit? I'm going to replace the positive, negative, and the PDC feed cables tomorrow and I'm hoping the Napa guy knows what I'm talking about, so part numbers always make it easier. The spare harness I have is also from a 93, so for all I know the wires are in just as bad shape. If I can't get the wires, I'll use the spare harness, but that's a last resort at this point.

It bolts to the front of the PDC with two bolts IIRC.  it's a flat two holer terminal.  I'd imagine you could replace it with a 2ft length of cable and two ring terminals on each end.

We jumped the starter with a set of jumper cables right off the battery and it fired right up. Got the cables swapped out and that seems to have solved the issue for now. Time will tell.

Okay, we load tested the battery three times and it kept checking out in perfect shape, put the battery charger on it to see if the voltage was just low and it had a full charge, tried to jump the starter with a screw driver and it refused to turn the engine over. The fuel pump clicks on, and all the lights work, radio works, and the voltage is good. My dad tossed the load tester on the battery and switched it on and it sucked it down to 6v...amps, one of those. Tested the battery and it was still good, so we're thinking it might be a bad battery cable.  The cables look to be original and we already put a new clamp on the negative post because I cracked it a few years ago trying to tighten it because the lead was so old. Does anyone know how the positive wire coming off the battery connects into the fuse box? I have a spare harness I can take apart but I'm not home at the moment and I figured I'd ask the higher powers on here.

on mine (95 YJ) the alternator + goes through 2 fuses 50Amps each and joins the positive from the battery

That's inside the PDC though.
