XX should be on, the Volts position will read 11.9 to 12.5 volts (23.8 to 25 volts for a 24 volt system) and the
Amps position should read -2.0 to -10.0 amps depending on your current load for the aircraft. Changing the
load will change the amps reading.

With the master on and the engine on, all lights on the VA-1A-XX will be off, the Volts position will

read 13.2 to 14.8 volts (26.4 to 29.6 for a 24 volt system) and the Amps position will read 5.0 to 15.0 amps
and reducing rapidly (shows batter changing current). Changing the load will not change the amps reading.
