I have two B&C regulators, one tied to the Continental 70 amp alternator and the other to a 20 amp B&C alternator.. The only time I have parked the plane outside overnight was on a short trip over Christmas. It got down to about 20F with a lot of frost. I cleaned off the wings& tail and hooked up an engine heater to warm the engine up before starting. After I started ( it started easy), my main alternator was not putting out any current. My B&C alternator/regulator were working fine. I taxied to the runway with no main alternator using the B&C alternator to charge both batteries. I did the preflight run-up check, and when I came back to idle the alternator started working. It has not quit since! It is hard to trouble-shoot when all is working as it should. Since my regulators are inside the cabin, I am speculating it is a regulator problem that is sensitive to cold temperatures. The cabin did warm up during the taxi and engine run-up. The airplane has not been parked outside since then so I have the problem on my questions list! Eugene Long Lancair Super ES glong2@netzero.net """ I have a B&C 14 volt, 60 amp alternator as well as one of their voltage regulators. They were trouble free for about two years until about 5 weeks ago when I went to go fly and couldn't get my alternator to come on line. It was an uncharacteristically cold and damp day when this happened (my plane is hangared, so it wasn't wet). After an hour of fruitless troubleshooting, I had to cancel my flight and head for the airlines to get where I was going. """
