Custom Battery cables Jeep cables

If you've found this page it's because you have a jeep with Y negative battery cable. I don't know why Jeep used that cable but apparently it's a hard cable to find. Below is what I did on my 97 Jeep Grand Cherokee and it seems to be working great. In fact, I think the volt meter went up slightly when I hooked up the new ground cable.

Note: This is what I did on my own personal Jeep but I do not guarantee that it will work for you. Perform this modification at your own risk.

Step 1: Disconnected the negative cable from the battery.

Step 2: Disconnected the other end of the negative cable from the stud on the engine.

Step 3: Using a box cutter, carefully cut the tape that holds the corrugated loom and cables together.

Step 4: Locate the "Y" in the negative cable and cut the wire going to the alternator as close as possible to the "Y" and crimp a heavy duty #8 5/16 lug (#10 is too small) on to the end of the wire (the one just cut). apply heat shrink to the end.

Step 5: Place the ring end of the new battery cable on the engine ground stud, then install the alternator ground wire (with the new end) and replaced the nut.

Here is a sketch of what it all looked like when done:

Notes:

The chassis ground is about 4 inches longer than stock for ease of installation.

The cable is a little long at 30 inches but that is what the factory cable was.

If you want just the ground cable, you can order it here. If you want a set or a positive cable go back the the Jeep battery cables page.
