My gauge has stopped working, it lights up but does not show any information.
Before it stopped working it did say CCU at one point. But after it said that, it stopped working. No idea on codes or anything.
Do you have to do it while the sled is running? Is that how you reset it? I have been working on the sled for a month doing some work.i checked all my wiring and grounds all appear good.
Likely moisture damage to the circuit board of the gauge. I've observed the same symptoms on deluxe gauges quite often. Not repairable on a standard gauge.
I have a m8 that did the same thing today
I unplugged the main harness plug. The seal was not right and had let in snow.
So I blew it out , fixed the seal,plugged it back together and it worked like it should.
Never touched the thing, moisture still behind the gauge, started my sled yesterday to bring back into the shop and the gauge worked, no CCU code, no flashing, showed my rpm, and my speed. I think I'm going to take it off and throw it in some rice, take it apart and put some of those moisture absorbing packets inside it.
