My plane has flown little in the last 6 weeks and not at all in June until yesterday. The 'low volts' light stayed on (flashing at a low rate) during circuits and only extinguished completely after 40 mins flying. (Ammeter normal).
Does anyone know why the light would flash at a consistent rate (about once per second)? I thought 'strobes' but it wasn't that. What voltage do these low voltage lights come in/go out at?
