Bounder: Instrument Cluster Inoperative

[sgeissen]

97' Fleetwood Bounder - Workhorse chassis
I changed out a turn indicator bulb on instrument panel recently. My turn signals, seat belt & engine indicator lights across panel work but,
the speedometer, fuel, odometer, amp, oil & temp (All guages) now do not work??
I recently also changed out my battery on the engine and also removed the other 2 coach batteries and cleaned the terminals because they were corroded. I do not know if the problem started with the battery change or the indicator bulb.
I have checked all fuses under dash and engine compartment - all are good.
I am wondering if I have a ground problem?? The engine starts, coach lights work...
I wouldn't think that the instrument cluster would all go bad at the same time. I do know that it is a printed plastic circuit board on the rear of the cluster.
Any info greatly appreciated.
The instrument cluster appears to be an International Harvester)
Can these plug in panels be tested?

I think you answered your question to your problem. Find a ground wire on you dash display and run a new ground wire to frame of chassis or a fuse panel.
