Yes: you need: ON-ON-ON as many of us use for - Fuel pumps ie: Off - Fuel
pump - Fuel pump+Primer. or Battery/Alternator ie: Off - Battery -
Batttery+Alternator

Can anyone tell me what the connector is that connects the antenna into the back
of a Cessna ARC RT-459 transponder? Thanks, Bradley

Look at these pictures and see if they look like
they would mate with the connector on the rear
of the transponder . . .

| Subject: | Intermittent Generator Problem |
While on a cross country flight last week, I got a low voltage
indication in my Lancair Legacy, wired using Z 13-8. I turned on the
SD-8 aux alternator and the voltage increased to the low end of the
normal range. I also noticed a whine sound in my headset. If I turned
off the main alternator, the whine went away but the voltage sagged. (I
have an all electric airplane and the SD-8 won't carry the full load
unless I shed loads, turn the master switch off, and run on the E-bus.)
I turned the main alternator back on and the whine sound in my headset
returned and the voltage returned to the low end of the normal range. I
flew that way for about 15 minutes and the whine suddenly stopped and
voltage jumped up to normal. I turned off the aux alternator and
completed the flight normally.
Everything was perfectly normal for the two hour flight home.
Any ideas what caused this? Since the first symptom was reduced output
and a whine in the headset, I initially suspected failed diodes inside
the alternator, but when it healed itself, I thought it might have been
a brush problem inside the alternator. After 15 minutes, whatever was
causing poor brush contact went away? I'm grasping at straws here.
I am so thankful for Bob's Z 13-8 architecture, which allowed me to
continue the flight without breaking a sweat! Thanks, Bob!

I purchased 2 Infinity sticks for my RV-8A, planning to use all the switche
s for various HOTAS functions. I ended up using only the Coolie Hat trim sw
itch, the trigger for PTT and the paddle switch for flaps. In the end, I fe
lt the risk of inadvertent fumble fingers activating/deactivating other fun
ctions overrode any perceived convenience. However, other folks have utiliz
ed all the switches very successfully. As with most things in the homebuilt
world, whatever you think works best for you.

If you want a Carling switch, I used Carling L52E166A77. It is a 24V light. If
you need 12V just go to there website to configure it. The important part is
the L52E. I am using it as a OFF-Low Boost-High Boost switch for my fuel pump.

I suspect you're losing an output diode in the alternator.

| Subject: | Re: Intermittent Generator Problem |
About intermittent alternators..... Once I had to chase a mystery
problem. Alternator would go off line, later come on line. I later
chased down a hairline crack in the stationary stator windings in the
case where it entered a swaging boss. When the alt. go hot, the
hairline crack would open and after the alt. cooled a little the wire
would make continuity and charge again. I suspect that the heavy wire
was damaged during manufacture and would not show up until the alt. put
under heavy loads in hot conditions. I had to use a magnifying glass to
finally view the crack.....
If it is not diodes, then look for this stator wire problem.

Yeah, that's a quirk of how the system handles Eudora
postings in the digest mailings. See

I think you'll see them properly if you access the

Bob,
Is there a suggested wire size (or rule of thumb) for the ground coming off
the aux alt. capacitor in Z-131/8 Rev. R ?
Thanks
