My Isspro Pyrometer (installed 9/02) just quit working. any sugestions where to start looking? Sensor is post Turbo.

Check all of your connections and the wire for areas that may have worn through. The probe may have failed as well.



You might want to get a hold of Issopro for their trouble shooting procedures.

Does yours use an electronic box in between the thermocouple and gauge, or tc/wire/gauge?

There are a couple different things to check.



When your probe is heated up by the exhaust, it send a very small current to the gauge that is measured in Millevolts. Because of this, it is essential that the cantact be clean and connected well. On that same note get ahold of Isspro and ask for directions on how to test the probe, thermocouple wire and the gauge. They will probly tell you to take a torch to the probe and measure the mV that the probe is kicking off (you will need a multi-meter). Then there is a procedure for testing the guage but i can not remember it (sorry) but if I remember right it's very simple. Hope it helps.
