All dash guages quit working

[rickinama]

I have a 2006 HR Imperial 42 foot. All of the dash gauges had quite working. I had taken it to a couple of local rv repair facilities that did not have any idea on how to fix the issue. I went so far as to call the Holiday Rambler repair facility in Alvarado, TX - only to be told I would have to take it to the HR facility in Indiana. As I was trying to figure out how and when I could take the coach (minus dash gauges) from Amarillo Texas to Indiana, a friend told me about Bigham Automotive in Lubbock, TX. I was able to set up an appointment and get the coach to them. They quickly diagnosed the issue, that involved significant rewiring and relay rebuilds. They provided an estimate of cost that seemed fair for the amount of work that needed to be done. Rick Bigham was constantly in contact, keeping us up to date on the progress. The work was completed in a timely manner and was within the price estimates. I highly recommend that if you need any work done on a Monaco chassis that Bigham Automotive be your first choice.

Thanks for that report. I have a 2005 Imperial (could not afford one like yours) and had a similar issue that turned out to be a bad ground. Sorry you had to do all that work. Travel safe!

More than half the time it will be grounds. Keep in mind the coaches move around a lot while driving over time. When built they move down and across the assembly line pretty quick.
I have checked front to back of coach and found more my fair share of bad grounds, poorly crimped connectors or not weather proof.
Happy hunting.

I lost a few gauges in my 98 Dynasty and they all worked if I ran a wire from the sender
to the gauge. The problem turned out to be there is a plug that came apart in the side
area beside my left knee. There is also a plug in the dash area. I has lost trans and engine
temps and oil pressure. Then I lost the tach. Hope that's the problem for you. I new I had
an open circuit somewhere but I didn't know the wires went into that area. It took a long
time to find it.

I have a single white wire that appears in the battery area that I forgot to reconnect when I serviced the batteries a couple of years ago. Lost all gauges until I put it back.

Pretty sure (memory not 100%) that it was a specific ground back to the battery.
