Bob - where is an easy internet site to find the pinout diagram for Apollo
GX-65? I know the GPS data output I need is on pin 5 (to power a trio
autopilot) but would like to confirm the pinout and be sure the numbering
system I have in my mind is from the "back" of the unit looking at the
serial port - thanks

| Subject: | B&C voltage regulator low voltage warning |
I have a B&C voltage regulator that controls one of their 60-amp,
12volt alternators. One characteristic of this regulator that has
been there since day one is that immediately upon starting the engine
I get a steady low-voltage light (LED), even though the measured
output voltage is normal. By the time I do a runup and take off the
light goes off. It is a steady light, not the flashing light that
would indicate an actual low voltage condition. I went to a lower
bypass resistor, but it is still there. Anyone else have the
problem? For now I just ignore it.

thanks Ralph! I'fe found the manual on line but it does not have a
pinout.diagram, nor a list of the pin numbers and what they are. I did find
on the tru trak web site that 5 is GPS and 22 if the GX has GPSS
thanks

Cheers,
I have read that some are substituting race-car kill switches for
battery contactors. At present I plan to start with only about 20 amps
dynamo and regret the constant load of a contactor.
If you are operating such a devise, I would admire a short
description and appreciation of its use - and perhaps a point toward a
useful source. US or UK no problem.
Thanks,

I've attached a UPS full stack wiring diagram that includes the GX-60/65
(same pin-outs). In case it doesn't come thru:
RxD1 = pin 4
Serial Gnd = pin 3
TxD1 = pin 5
TxD2 = pin 22
Serial gnd = pin 20
RxD2 = pin 21
If you look closely at the connector, the pin numbers are molded into the
plastic. I need really good light and/or magnifying glass to read them, but
they are on all my UPS radios with D-Subs.

??? bypass resistor? Don't know what that is. Oh, you're using
a LED. Try hooking a incandescent lamp up temporarily and see
if that works. The circuit was not originally designed to work
with LEDs. What LED resistor values are you using?

What does it do when the engine is running and the
alternator is shut off? Does it come back on steady
or does it flash? I think your resistor values
need to be reviewed.

How much of a reach is it to get at a switch mounted
right next to the battery. Harbor Freight sells a
device that looks like this . . .
http://tinyurl.com/2u7wgj
. . . for about $6.00 . . . oops, strike that. They're
on sale right now for 2.99 at http://harborfreight.com
as item #92688. Marine parts dealers sell a variety of
battery switches too.
I'm working on the alternator drive stand and will
need some high current, manual switches. I think I'll
run down tomorrow and pick up a fist full.
Obviously, for use as a battery contactor replacement,
you want it to be within convenient reach of the pilot.

West Marine has several in their on-line catalog . They have full
descriptions and specs.
The one I use in my truck works great but sadly is very robust for an
airplane. Check their catalog.
Summit Racing sells similar ones.

I would like to subsitute an LED for the Low Voltage bulb that came with
the B&C LR3C-14 . I posed the question to Tim Hedding @ B&C and received
this in response.
If you use an LED instead of an incandescent lamp, install a 470 - 510 Ohm,
1/2 Watt, resistor between terminals 3 and 5 of the LR3C-14 (or the SB1B-14)
so that the LED does not glow dimly all of the time.
