Low volts warning light?

elprez

Hi friends. Just picked up the BS Baron Pro today. For some reason the plane constantly gives a low volts warning message on the dash. After a few minutes the avionics power down (i assume for lack of power). If I come off of idle and give it a little throttle the light goes out, and the avionics return on. Both engines are running the entire time. As soon as I lower the throttle to idle it repeats. I figured I would try here before I go down a rabbit hole trying to figure this out. Thanks.

You need to have about 1200rpm for the generators to work IIRC

To fix this I adjusted the response curve of my throttle to make my zero-power point equal 1200 RPM. I use spad next with a virpil throttle. Easy fix. Thanks for the suggestion.

I don't know if this was clear from above, but I just wanted to confirm that this is the intended behavior, and not a bug. This is very typical in aircraft with alternators and analog voltage regulators. It's actually often one of the first things that I hear real world pilots remark about when they test my aircraft, "you even got the low voltage light correct!" In my own flying, the cabin lights dimming and pulsing at low RPM while taxiing is actually a great indicator that you forgot to return the engine to an idle RPM of 1,000-1,200, which keeps the battery charged, and the engine healthy. Always happy to answer if you have any more questions!
