I have checked for continuity in the tach and temp gauge wires. We have continuity. I have double checked that all the wiring is connected properly as per the diagrams. I can't get the two gauges working. Had it out for the first run of the year yesterday. I noticed the tach slowly climbing (but not showing rpm) as the ride went on. After about two hours, the tach went all the way around and bottomed out. The temp gauge never moved at all. I would appreciate any advice someone could offer. I would be a lot more comfortable being able to read the temp and rpm.

Serial # A167154

Thank you!
