My son has a 95 XJ Country, and it's showing a code 76--Ballast bypass relay.
I have looked and looked and can't find this dang thing anywhere. Would it show this code if it was removed ?
Any help would be great.
Thanks, Don.

That code means there is an open or short in the fuel pump relay. This may help: Troubleshooting a Jeep XJ fuel pump.

If its like the old ones it should be on the drivers side inner fenderwell right next to the air box... A white ceramic ballast with two connections one on each end.

If it setup like the Renix ballast, on driver side fenderwell, a little metal piece with 2 wires connected to it, you can bypass this by connecting them together. And you will need to clear codes (I.E. disconnect negative batt cable for a couple minutes.)

Justin, what is the function of the ballast? Is it supposed to prolong the life of the fuel pump?

I think thats what its for, it makes it 12v into the fuel pump, so the voltage does not fluctuate with the alternator. I believe this is what dan (gerr) told me.

That's what I read too, it keeps it quieter. But every write up I read, said to remove it, and hook the two wires together.

yea, because they can fail, leaving you unable to start the vehicle.

The one on a '90 my son had cracked the ceramic block in half... I ductaped it back together, just like any proper Jeep repair, and it worked just fine after that!

Ballast resister was removed from the fuel pump circuit 94+.

The error you're seeing isn't from the ballast resistor it's from the bypass relay which is located on the pass side by the main fuse block it will be under the cruise control circuit or possibly mounted to front of fuse box. It is a relay that plugs into a socket wired directly into the harness.
