fiscus Posted April 3, 2007 Posted April 3, 2007 Last night I installed a CD player into my MJ using the PO's rigged up wiring for the time being. (hot wires to fuse box under dash). This morning I drove to work & my gas guage was pegged all the way to the right. Is there a fuse or something that I could have popped to cause this? The speedometer seemed to be working fine, but the rest of the cluster is the idiot guages. I gotta have a gas guage, I have a leaky tank so I can only fill it 1/2 way...
87manche Posted April 3, 2007 Posted April 3, 2007 check that it's not doing something funny with the ground. Gauges need a god solid ground, and if you're backfeeding voltage somewhere into the dash it would certainly freak out the guage.
Eagle Posted April 3, 2007 Posted April 3, 2007 Your speedometer is mechanical, so the fact it works is irrelevent.
