| Subject: | voltage regulators |
--> AeroElectric-List message posted by: TimRhod@aol.com
Can any one tell me where they usually mount voltage regulators in a canard
pusher? I seems with three or four wires needing to go to the panel, warning
light, panel ground, and only one going to the alternator that it would be
best to put it in the nose. Tim Rhodenbaugh, Velocity XL, timrhod@aol.com
Thanks

That would be my choice.

You can have the alternator repaired at an automotive
shop . . . if the regulator is bad, they'll replace
it. Did you notice the voltmeter in your airplane
before the trip? Was it indeed running 16 volts or
more?

The idea was that all cranking currents would be carried by
no part of the airframe or any components that held it together.
Hence, the 5/16" brass bolt intended to connect cockpit side
grounds with engine compartment grounds. It wouldn't hurt anything
to run a fatwire jumper between them . . .

We always mount them to the canard bulkhead, between the lift tabs.

. . . it is indeed a vague notion. About 35 years ago, red
flood lighting was standard in the small Cessnas . . . for lots
of dollars extra, one could install the optional red or blue/white
post lights. One can find about as many opinion/reason combinations
as there are pilots . . . some of whom will have never flown at
night.
EVERY color of light, if kept at a level just bright enough
to see that all is well, will probably do just fine. Individuals
may find that they favor or have problems with one color over
another but I'll bet that has more to do with individual
physiology than for any standard rules-of-thumb for cockpit
lighting. Besides, if you're using flood lighting, changing
colors later to suit your personal preferences is easy . . .

I bought one of those LED gooseneck lights with 6 LEDs in it - but I'm
replacing them with two red, 2 green and 2 blue LEDs, and a 6-position
DIP switch to program whatever color I want. It will be interesting to
discover what color I find to be most effective, and what others prefer.
-John R.
(Actually, maybe I'll put in TWO 6p dipswitches, and a on-off-on DPST so
I can compare two different colors in flight)

So, you feel it is worth a hole in the firewall to connect the two grounds?

What benefit does this offer? Is it corrosion, or is it interference with
other electrical stuff, or what?

After 20+ years in the merchant marine, on the
darkened bridge of a ship, I've learned that there is
good reason for the traditional red lighting. I feel
that the red lighting can be cranked up enough to be
useful, yet still allows the eye to recover instantly
when vision is taken back into the darkness outside
the window. Other colors, turned up to a useful
intensity, are harder to recover from.
Of course, the option is to run any color at a lower
level. But in general, my vote would be RED.

Where did you get the 6 LED gooseneck light?
Thanks,
