Hi, I have the 2005 Dolphin. Recently all my gauges quite on my dash. The odometer and light is on, but none of the gauges; speedometer, has, coolant and tech work. I have checked all the fuses and wiggled wires at the dash, any ideas would be so awesome. Thank you!

probably needs to be sent to ultra rv for a rebuild, had to send mine in on my 05 dolphin.

Here's the link:

The difficulty is that their basic product is a replacement LCD screen not the entire board. That may be because of this: "Changing the LCD screen DOES NOT change your mileage. Mileage is stored on a separate memory chip on the circuit board!". Loss of the total mileage number when replacing the gauge circuit board is the problem. (potential legal consequences)

I agree, a call to them would be my next step.

with all due respect one of us is misinformed, i had my dash done at ultra and here is my understanding, 1. my guages now work, 2.the mileage is stored in the eprom in the vehichle computer, law. 3. they replace all the guage motors. cost i don't remember off hand but about 350.00 i think. jmo.

Grab a voltmeter and check the wires. Fuses can be fine but connections may not be.

Check both sides of any of the gauges. The positive and the negative side that is.

You could have a bad ground or bat power. Putting the meter on the negative lead IF you have voltage on the positive lead of the gauge will show voltage if the ground is bad.

The ignition switch may not be sending the voltage from the fuse block.

Yup - years of restoring/maintaining little British cars taught me to check the simple stuff first, ground connections being paramount!

Thanks everyone for the great advice. I sent the board into Ultra RV as suggested, they were great. Had the board back in a week, $299 and solved the problem, thanks again
