| Subject: | Re: USB Power Supplies |
FWIW, I purchased a single USB plug unit from Stein a few years ago.
Charges at 2amps, no interference noticed, looks good panel installed.
Wish a two port version was available from Stein back then.

I just went through the troubleshooting for that same configuration.
After doing the procedure for the LR3, one finding didn't match the
spec. I reviewed the results with B&C and they were able to tell me
with confidence the LR3 failed (1,000 hours) - could be repaired or
new. All good now.

Bob, perhaps you can help me find a SPDT (1-5) switch for flap control where the
bat doesn't rotate. Years ago you published a piece on how to make a little
flap lever out of a solid piece of aluminum that goes over the toggle and gets
held there by a couple of set screws. The only ones I have found all have
bats or toggles that rotate and this is not good. Do you recall which switch
it was? Thanks!

Thanks, guys. Actually, I have the flap handle (toggle). I need the[u] switch[/u],
one that has a bat that doesn't rotate. All the ones I've tried have a
toggle that rotates in the switch such that the flap handle will not stay horizontal.

| Subject: | Voltage Regulator Damage? |
Folks,
I am writing my POH, patterning it after the POH for a Vans RV-12. That
manual has a warning, "Do not turn off the Master switch with the engine
running except in an EMERGENCY situation. Running the engine with the
Master Switch off may damage the voltage regulator."
I have a Lycoming motor with B&C voltage regulators, LR3C-14 and SB1B-14.
I have never seen a warning like in the RV-12. Is this something
Rotax-specific? Should I have a similar warning in my POH?
Thanks,
-- Art Z.

Art:
Rotax is RATAX... Forget about IT!
Now, since you are flying a Lycoming the MASTER should be a SPLIT
MASTER/ALTERNATOR.
Automatically with a Split Master when you shut off the Master you also
shut off the Alternator.
If the Alternator (ALT) is OFF you removed voltage from the Field of the
Alternator.
NO DAMAGE will be done to the Alternator or the ACU.

Barry,
I appreciate your thoughts but I have three separate switches: Master,
Alternator, and Backup Alternator.
For all the detail, here is my wiring diagram:

I have an RV-12. A couple of years ago, my PC680 battery failed during flight
with an internal broken weld, later found by Bob N. The battery was effectively
disconnected from the aircraft electrical system just as if the master switch
was shut off. No damage occurred to the voltage regulator or any other component.
The symptom during flight was unstable voltage, swinging from too high
to too low. You can read about it here:
http://www.matronics.com/forums/viewtopic.php?t=16762906&postdays=0&postorder=asc&start &sid=5c9d8b0067c9a54cf7a0a3c0ea1ac72f
I see no reason why an open master contactor during flight would cause damage
to the voltage regulator. After all, the regulator turns itself on and off many
time per second during normal operation
