All Gage's except the speedometer and tachometer. I do understand that these two Gage's are fed from the computer and the rest from sending units. For the engine oil pressure, engine temperature, alternator, and fuel Gage's, I have checked fuses, sending units and wiring harnesses for loose or broken wires, and have even changed out one of the Gage's but nothing has changed. I have read forums and have not been able to gather any information to assist me. Any information or suggestions will be greatly appreciated.
