Ok so my autometer pyrometer gauge started acting up and was wondering what to check first. It don't seem to work at all i mean the needle doesn't move at all until i get up to speed and am not giving it any throttle the needle will go up to say 7 r 800 degrees but as soon as i give it any fuel it goes to 0. Any ideas would b appreciated, do i need to look at the probe r clean it maybe? The wires look like there all connected still so maybe just buy the new wiring harness with a probe? thanks for the help..
