How many of us are there? Owners of Dodge based RV's?

Oh the gauge troubles and the voltage regulated sensor behind the cluster panel. Last summers nightmare. Ended up grounding the circuit board directly to the firewall. My failed gauges come to life!

Just make sure it's the ground copper trace that you connect to the firewall (or another suitable ground source).

If indicator lights share a copper trace, that's probably the ground. (Instrument illumination lights often share two copper traces ... one for ground and the other for +12vdc).
