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 bobf ________________________________ Message 2 _____________________________________ Time: 06:04:58 AM PST US From: Gary Casey Subject: AeroElectric-List: 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.

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 bob On 6/24/07, Ralph E.

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.

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.

US or UK no problem. 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.

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 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.
