Engine/Transmission (1998.5 - 2002) SPA Guage trouble

[Big John]

I have a boost/EGT digital setup from SPA that is giving me trouble. It started with the light going out about a week back. Yesterday the EGT started giving false readings from low to high. May stick on a reading for extended period of time. Anyone with any advice?

John, I have had 3 of my SPA gauges do this same thing. Fuel Pressure, EGT and now rear diff temp. What I finally did that worked for the first 2 was to cut off the factory connectors and just solder the darn sending unit into the wires from the gauge. That's drastic I know, but it worked. Except for the rear diff gauge... I am going to call SPA and get a bew sensor to see if that cures the problem.

Tom, thank you for the reply. I found my problem. One of the wires is broken off at the thermocouple. Looking for new one now.
