Finally determined the Ray Allen RP3 trim indicator in my aileron trim circuit was causing its breaker to trip, so, I removed it opened it up to check for any obvious defects - found none. When I talked to Ray Allen about this they didn't seem to surprised and offered to send me their RP4 at half price - the RP3 is no longer made. The panel cut out will have to be elongated about 80 thou (file time) but at least mounting holes are the same. Wondering if I should replace the elevator trim indicator at the same time in case its days are numbered to.
