I Have A 1999 Maristar 210 That Has Constant Issues With The Tach, Speedo And Voltmeter. They Sometimes Work A Little Or Sometimes Not At All. Sometimes One Works And Not The Others. The Water Temp And Oil Pressure Seem To Always Work Well.
Any Suggestions? Or Does Anyone Have Extra Guages Available?

Could be your MDC control box. These are notorious for getting water in the electronics from the speedometer tubes and causing problems with the guages. I had to replace mine a couple years ago. Fortunately it is an easy job to do yourself. I think the box was around $235.

I have an '06 X-15 and the guages go out all of the time. I have to wiggle the main plug in the MDC to get things working again.
