The racepak Avenger III guage is reading -99 for the all 3 EGT's. It does this with the sled running and turned off. I've tried hooking up a few different probes, but it does it will all the probes. For a few seconds it showed 1700 with the engine off, but then went back to -99 and has been stuck there since. Any idea how to fix? Thanks
