The oil temp, oil press, amp, and fuel level guages just quit at once, now a few days later the fuel level and amp guages work. or they will work once and then quit again. checked all wires, grounds, fuses, sending units, batterys at full charge, ect.... could it be the mmdc box?? thanks for any input.

I had a similar problem (intermittent). In my case, the Tachometer, which also includes the LCD display for Air Temp/Water Temp/Hours/Time/Depth was the culprit. This gauge had gotten condensation in the housing, causing it to fail. Because I could see the condensation, on a hunch, I disconnected ONLY this gauge from the harness--then all my other gauges started working normally. Reconnected and they all failed.

Ultimately, pulled the tach/LCD gauge out, left it in the sun for three days and the condensation cleared. Put it back in and all has been working fine since. Hope your fix is as simple.
