Lost gauges

2006 Diplomat PAQ, the 2 small trans and engine gauges at the bottom of the large fuel gauge have quit working. Does anyone know where to get a new gauge assemble. The Aladdin system shows the sending unit still working so I assume the problem is in the dash gauge.

Monaco daisy chained the ground on the gauges. Check to make sure the grounds are good.

Not sure who manufactured your gauges but I just got some replacement ones for my 06 navigator from
They bought a bunch of monaco parts when they filed for bankruptcy in 2009 I think.

I second dacwjames recommendation to check the daisy chained ground wire(s). I battled an OCCASIONAL and usually only a momentarily intermittent instrument panel lighting issue since purchasing our '99 HR in 2013. Finally, in 2016, I lost the ALL of the lights and gauge readouts across the ENTIRE dash instrument panel, and had to drive 1500 miles home with no gauge readouts or lights. For me, the biggest concern was that I had no way to monitor engine oil pressure!

After much persuation from the iRV2 forum members, I began chasing down a faulty ground. However, I was never able to find and isolate the faulty ground wire, and finally just simply attached another ground wire to the daisy chained instrument ground wires. VOILA! A fully functioning instrument panel again!!
