I have an RV-6A built by another so I am not the "enabled" repairman. I have two issues that I cannot find anyone to help me troubleshoot. My A&P is not avionics and the avionics shops around Kansas City do not work on experimental avionics since they don't have wiring diagrams, they're not STC'd, etc.
My problems may be as simple as loose connections, or not.
Here are my two problems:
1) Rocky Mountain uMonitor stopped tracking the fuel use (constantly displays 38 gal) and the gph (constantly displays 0.1). This occurred right after I got it out of the shop and, while it worked for the first half hour on the next flight, it stopped then with these symptons. If I never push the reset buttons then the 38 gal display will drop by 0.1 gal every hour.
The next problem began after another shop visit:
2) Navaid autopilot: When my 30 amp alternator gave up the ghost my A&P and I replaced it with a 60 amp alternator with built-in voltage regulator. We also rewired with a heavier duty gauge wire, from the alternator to the new 50 amp circuit breaker. On my first flight after, the Navaid autopilot did not work. The red led rate-of-turn indicator still works but the switch for TK-TC-WL does nothing.
I realize that these things may be as simple as a loose connection or a ground, etc., but I'm not qualified to work on this.
I'm looking for help and I'll fly anywhere I need to. In fact, though I live in KC I often fly to Dallas for business, which is where I am today. Problem number 2 began shortly before this trip. Is there anyone close with any experience with similar problems?
