I have a B&C gear driven standby alternator on my XP320 and am wondering if it can be tested while the engine is running from the cockpit, and if so, how?
My switches from left to right are Master, Standby-Alternator, Left Ignition, Right Ignition. My ignition is one mag and one electronic. My master switch has three positions, off, battery only, and on.
With the engine running, I turned off the master switch, turned on the standby-alternator switch and nothing, no power at all, not even battery.
So now, assuming the standby-alternator is functioning correctly, I presume the the master switch must be either left in the on position or battery only position. I'm concerned with just flipping switches from this point on as I don't know what would happen if I left the master switch on (main alternator) and then also turned on the standby-alternator.
I would think there would be some way to turn only the standby-alternator on and observe it powering the avionics, including a readout on the volts and amps.
Thanks,
Curt
