[Destroyer]

As previously stated by ByGraceAlone and others, instrument gages usually have two sets of wires. One set is for the lights (usually a blue wire and a black wire) and another set for the actual gage function itself. (Depending on the maker of the gage, they might use the ground [black] wire for both the lights and the gage function). What I'm trying to point out is that just because your lights are not working is not necessarily an indication that the gage is bad. In order to find out if the gage is bad you'll need to check each gage's function. For instance, if it's a tilt up/down gage you'll need to check the tilt switch on your engine, and the wires leading from the switch back to the gage, etc. Think of the lights as a completely seperate system that just happen to share the same space inside the gage housing as the gage function does.



And ... just for information's sake and printed in good humor:

Gage is the preferred spelling for instruments and in manufacturing in America.
Gauge is also correct and is gaining acceptance.
Guage is not in the dictionary .....yet. ...It might be where Elmer Fudd parks his car however ... the gu..agj
