Rob Posted September 16, 2022 Report Share Posted September 16, 2022 Lately I have An electrical problem. After starting the engine my voltage shows 13.8 volt. After 5-10 minutes it drops suddenly to 15.4 volt and keeps dropping till 7.5 volt ( after 2 1/2- 3 hours flying, ( all electrical equipment fails of course). Yesterday I put A new voltage regulator on my plane with the sams results as above. A mechanic did some checks but did not find anything yet. {Plane is about 1 1/2 year old) Does anybody has any idee's? Grt Rob Quote Link to comment Share on other sites More sharing options...
Foley Posted September 20, 2022 Report Share Posted September 20, 2022 test batteries for loading, test charging, trace ground wires from battery to engine and engine to voltage regulator. make sure wires are secured and tight everywhere. loose connections will reduce charging efficiency. if your losing volts its either battery wont charge, generator not charging, of wiring is not secure enough to enable charging.
