Dead gauges & radio

[Doball]

I was removing the wires for the hard top tonight and bzzzzt the radio died. No bigie, just a fuse, right? when I got done and started the Jeep to move it, none of my gauges worked. The lights in the cluster work, 4x4, and e-brake light work, but nothing in the gauge cluster work. Looking at the wiring diagram it makes sense that I blew the cluster, but that doesn't explain the radio not working. I disconnected the battery for about 15 min and the gauges still don't work. I can't see where they would be related. Any Ideas?

is your radio aftermarket?  did the person who wired it pull power from your gages (not normal)?  seems odd that wiring in your top would be the same ckt as your gages.

Jeremy has a good point about the aftermarket radio being wired incorrectly if the previous owner had put it in. When I replaced the radio in my XJ I couldn't believe the mess behind the radio. It was no wonder the power was going in an out on it.

No the radio is good. Not a twist and tape job, used the real harness adapter.

check the fuse box under the hood. I think there is a gauge cluster fuse under there. Maybe

[Doball]

Done, ALL fuses are good. Looking at the Hanes wiring diagram, there might be a fuse in the cluster itself. Other than that I'll have to find one somewhere else. The only problem with that is I don't know where the odometer reading comes from. The computer or the circuit board on the gauge cluster.

is it digital display (the OD) or analog?  if digital, it probably has a memory feature either in the board or computer (probably board) and is driven by the VSS via the ECU, if anolog, probably driven off a motor which gets its signal from the VSS throug the ECU

[Doball]

Alright, I found it. A burnt wire coming from the power box under the hood. When you use a meter to test a fuse, test the voltage coming off of both sides of the fuse at the same time.

congrats!

Yeah...  Uh..  All I got out of this whole thread was:

Have a wiring problem?

Call Doball or Rocket.

True dat!  I can wire up anything! (esp. after completly re-wireing my el camino)

Me and wiring, are like the fat kid and the running track. We can both get it done it just takes a while.
