Hello!

Does anyone have the chevrolet motorhome chassis service cuide for a 1990 - 1993 P30? I have a 1991 HR Alumalite 33ft and the oil pressure gauge is pegged all of the time. I cut the wires going to the sending unit but it still pegs so i think it's either the gauge itself or a bad wire. The gauge is in a PC board on the back of the instrument panel so it's hard to trace without a wiring diagram. Thanks for the help!

I think what you need is the GM light truck manual. I don't think the motor home chassis service guide has that information. I will check the dates on mine tomorrow to be sure.

How many wires go to the sending unit?
