Sounds like the regulator. If the regulator fails it will either stop charging or go overvoltage which potentially could overcharge the battery and cause a fire.
Make it part of your regular inflight checks to scan all the engine instruments and you can turn the alternator off if you get an over voltage situation. Regulators are cheap. Either you will have a Bosch altenator with an internal regulator. It is the black unit at the back of the alternator held in by two small bolts or.... .... if you have an alternator with an external regulator, it will be mounted on the ledge next to the RHS carburettor and most likely will be an aluminium case unit with cooling fins. Both are cheap at auto shops. regards Rob Rob Thompson 0429 493 828 On Sun, Sep 3, 2023 at 10:25 AM Tom Preisser <[email protected]> wrote: > While flying today I noticed that my voltage would go up from the normal > 14.3 to 14.6 volts to an occasional 15.3 volts.
