 |
|
<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]--> I'm using the Z-13/8 Power Distribution diagram in a Glastar with dual Dynons.
The FlightDek D180 is connected to the Main Bus and the EFIS D100 is connected to the Endurance Bus. Each unit monitors it's bus voltage. In normal operations I fly with the MASTER switch and AUX ALT switch ON and the ALTERNATE FEED switch OFF. I have experience no problems with this configuration.
I recently implemented an checklist procedure to test the power distribution circuit and alternators on startup before taxi. After starting the engine and checking that the MASTER and AUX ALT switches are ON, I check that the voltage on the EFIS is .6 V less than the FlightDek. I then switch the ALTERNATE FEED ON and check that the EFIS voltage is the same as the FlightDek (over 14 V). I then switch OFF the MASTER and check that the FlightDEK voltage is 0 V and the EFIS voltage remains above 13.5 V. I then turn the MASTER back ON and the ALTERNARE FEED OFF and I'm ready to taxi. This procedure appears to be working fine and I have experienced no problems in flight.
When I reviewed the flight log from the FlightDEK however I discovered that I was inducing a significant negative (MASTER OFF) and then possitive (MASTER ON) current (over 200 amps.) for a short period of time in the main alternator when I'm performing this test procedure. Will this damage the alternator?
Thanks
