2nd Gen Non-Engine/Transmission Pyrometers

I have Isspro, and sometimes it gives a false low reading.

I have seen it sitting on the bottom of the scale. The connections are tight but if I reach behind and wiggle the wiring the reading changes.

Should I try cutting out a few inches of wire next to the gauge and re-connect? Or maybe the fault is inside and the bumping when I wiggle the wires makes the connection?

Any ideas?

I had exactly the same thing happen to my ISSPRO pyro a couple different times. When I bumped the gauge with my hand, the needle would jump up the correct reading. Both times, I checked all connections, etc. , and finally found the thermocouple probe to be hand loose in the exhaust manifold. Tightened it back down, problem solved.



Don't know if this will work for you, but it's a quick check and fix.
