On to my next project. The Isspro R607G pyrometer hasn't worked for a while. I built a test rig and confirmed the gauge works and indicates the correct temperature for each reference voltage. I connected my test rig where the thermocouple wires would connect to the R660 lead wire so I know the lead wire is OK as well. I'm pretty sure the thermocouple is history. Now I need to figure out what probe to order. I'd like to have the replacement on hand before removing the old one since the old probe has been there since 1993. I fully anticipate it falling apart upon removal. Not sure which probe to order. The current probe is installed in the exhaust pipe just off the drivers side manifold. The original installer welded a bung onto the pipe and the probe is the threaded type. I'm assuming I need the R650S, but every time I assume, I end up in trouble.
