MHRookie Posted June 8, 2021 Share Posted June 8, 2021 All, 2003 Monaco Dynasty princess 42’. Fuel & tranny gauges quit working. Does anyone know where the ground bar is behind the dash! I’ve taken the panel off the driver’s side and it’s not jumping out at me... tranny temp gauge don’t wiggle, fuel gauge tries to move at key on but don’t move. I tried adjusting it & that’s not it. thanks for any help.. Kurt Link to comment Share on other sites More sharing options...
klcdenver Posted June 8, 2021 Share Posted June 8, 2021 Just run a new ground wire to one of the gauges and see if that is the real problem. Link to comment Share on other sites More sharing options...
timaz996 Posted June 8, 2021 Share Posted June 8, 2021 It should be far forward under the top of the dash. Copper wire connecting to an aluminum ground bar doesn't work well. Who at Monaco thought this was a good idea? Tim Link to comment Share on other sites More sharing options...
Dr4Film Posted June 8, 2021 Share Posted June 8, 2021 I thought the ground wire to all of the dash gauges were daisy-chained in series. Am I wrong? I agree with a previous poster, easiest trouble-shooting step is to hook up a separate ground wire to see if it changes anything. Link to comment Share on other sites More sharing options...
Chuck B 2004 Windsor Posted June 8, 2021 Share Posted June 8, 2021 On some coaches the dash gauge ground buss is located on the generator side of the firewall. Loosen up all the screws on the ground buss and spray it with WD 40, retighten. Road vibration will cause the wire nuts on the back of the gauges to become loose.
