Mileage gauge problems


Recommended Posts

The biggest problems with dash gauges are the connections on the back of the gauge are loose.  The ground wires on the back of the gauges are daisy chained from gauge to gauge ending up on a ground buss bar on the firewall.  Loosen up all the screws holding the ground wires to the buss.  Spray them with WD 40 and tighten the screws up.  Clean up the back side of the buss bar with fine sand paper.  

Gain access to the back side of the gauges and tighten up all the nuts.  

Hopefully that will solve your problem.

All of the individual ground wires, from each of my dash gauges,  go under one single screw in a "ground lug" that looks like this:

That lug must be properly grounded to the frame of the coach.
