My Greddy P/H/W 60mm EGT gauge is stuck at 300. I replaced the Probe 3 months ago, so I pulled it again and it looks great still minus the soot on it. I pulled out the control module and checked for constant 12v, switched 12v, lighted 12v, ground and all was good. I reseated all the plugs on the control module as well and that didn't help either. Th gauge does light up, so I know its getting power and ground. Also when I disconnect the probe from the contoller the warning light flashes like it should. It just seems as though the needle itself doesn't work because when I adjust the warning level the needle doesn't move, but when I turn it too low the warning light will come on. Any suggestions greatly appreciated!

 

It started working this morning... Damn gremlins!
