so i flip my battery on, and my inverter and ive tried both normal and alternate as well as different combos of batteries but my voltmeter doesent do anything, its like its broken, i have accusim installed and updated it as i should and all that but...the voltmeter just doesent seem to work, im on the steam edition of fsx too, maybe that has something to do with it? and no, i dont abuse spoopy...(the name of my b-17, dont ask) its the only thing ive noticed that doesent work, everything else seems fine...too bad there isnt a diagnostics tool for a2a aircraft haha

The switch directly under the voltmeter needs to be turned to check voltage from each generator.
