Guage Trouble
 

I have the isspro ev2 guages in my truck. The egt guage isnt working, sits around 200* at all times and never moves. I have checked all connections and they are good. Im thinking its either the sending unit or the guage itself. If u could i would like to get this issue fixed. Thanks

Do you have a multi-meter (volt-ohm-meter) handy? If so, please unplug the thermocouple down near the exhaust (molded sealed connector) and measure the resistance between the pins on the sensor side. It should be around 1 ohm. Please let me know what you find.

Best bet would be to give them a call. You can test the probe with a heat gun or truck running and a volt meter. I had this happen a few weeks ago and it ended up being the probe $.02
