I need some advice please.
My ’73 Arrow 200’s alternator puts out 13.66 volts when idling. When I turn on the conventional landing light, the volts go up to 14.27. On the take-off roll it sat there and increased to 15.10 volts while the gear cycled. In the cruise it returned to 14.30 volts. At the gear down the volts reached 14.97 volts and went back down to 14.3 volts. Are these readings within the normal range?

Thank you kindly.
