Voltage Regulators

[macaman]

Great News. The problem turned out to be the Voltage Regulators. We thought we had a related problem months ago when this all started when the High Voltage light would flash. Turns out that the maintenance manual says that this signals the need to put different voltage regulators in. I don't have the part numbers with me but the problem was that the original Cessna part number was listed as a possible replacement for the Zeftronic regulators we were using but not the other way around. I have yet to tell the A&P that made the mistake as I'm sure he'll feel awful we spent so long trying to figure this out. Just an expensive lesson learned I guess. So glad to finally have this finished. A couple days to finish the annual and we'll be back in the air. Hope this helps anyone out who may be having similar troubles.
