I just installed my egt gauge and probe a few days ago and it's not working. I double checked all the wiring and connections and everything seems to be correct. I have a VDO gauge and a TRE egt probe.
The gauge did work for a split second but went back to zero after going up only one notch on the gauge. Is there any way to test if the probe or gauge are working properly? A list of things to check would be great. Thanks!
