Fellow RVers,
I have a RV-7A with Titan IOX-360, Plane Power alternator (with internal volt reg), VPX (Vert Power sport) and dual Dynon Skyview Classic. For some time now I've been experiencing fluctuating and high ammeter readings on the Skyview EMS (jump from normal to 90+ Amps) anytime I fly. At first I was quick to land but after replacing the alternator, checking all wiring for loose connections, and replacing the battery (PC 680) I am still having the same issue. This only occurs once the engine is warmed up (happened much less in winter when temps were cooler) so I suspect maybe the voltage reg or one of the shunts is overheating and causing the faulty readings. There has been zero signs of damage due to high amperage on any wires, battery, etc and I even had the old alternator bench tested and both it and the volt reg checked out fine (so now I have a spare...). I am considering making a hole in the front left intake air ramp and running a hose to put air directly onto the voltage regulator to cool it...I have seen others do this but I'm still shooting in the dark and was hoping this sage and experienced group might offer thoughts, experiences to help. TIA! and pictures attached.
