Flashing alternator lights

[Red Air Rambo]

I don't know if the alternator field fuses were the culprit or the 6 year old alternator restart batteries, but the problem is now fixed with 10 hours and not a flash.

Well, I'm happy to report the installation of two Zeftronics regulators solved my flashing alternator lights problem. I still have a 1+- variation (less than the previous 3 volts or more) in voltage as the alternators cycle but that's probably due to some resistance in the alternator switches or circuit breakers.
