Ok. I think I will give that a try. Is there a particular diode you would recommend
to use for this.
I am not quite ready to run the engine yet, so I will try to test it using the
main battery to charge. This will make it easier to check current flow at different
stages of battery discharge on batt #2. Do you think the main battery
alone will give about the the same current flow as if the alternator was on
line.

You can't charge a 12v battery from another 12v battery. You need ~14v to
actually charge, which the 12v battery can't deliver.

I agree with Charlie.
The diode that I recommended in a previous post, DSS 2x121-0045B Schottky, has
mounting holes, an isolated (insulated) base, two independent diodes in one
case, low voltage drop, high current capability. The disadvantage is that it
costs $20 plus shipping. It is available from Mouser or Digikey. Other Schottky
diodes are available in a TO-220 case for as little as a dollar, but the
case might need to be insulated from the aircraft and the terminals are not as
robust.

Try searching ebay; I've seen some pretty good deals there.

| Subject: | Wig Wag difficulties |
Howdy,
I've wired up my landing lights using the Tridon flasher and two
switches according to the WIGWAG WITH B&C SSF-1 FLASHER page 5.0 diagram
and I can't get them to work right. When I put the first switch in the
center wig wag, position, the flasher just buzzes. When the second
switch is put in the center position, I sometimes get 1 flash and then
it just hangs with one light lit. I reversed the 2 and 3 wires at the
flasher and the behavior switches sides.
For lights I'm using the Baja Designs Squadron Pro Leds at 42w each and
I put the 5w 75 ohm resistors across them as in the drawing LED WIGWAG
WITH B&C SSF-1 FLASHER, page 1.0.
I've verified the wiring and the switch functions with a continuity
tester. I changed out the flasher and it worked perfectly for about a
half a minute. I turned it off to install the switches back in the panel
and when I tried it again, same hang up.
Any ideas?

I can't find the flasher on their web site, but if it's buzzing, that
sounds like it's one of the old style mechanical 'vibrator' style
flashers. If you use them with LED lights, the lights probably don't
draw enough current to make the flasher 'switch' between the lights.
FWIW....

Yup, and that's why I put the resistor across the light per Bob's
drawing. B&C doesn't seem to carry the flasher anymore but it is still
available if you look around for it. Tridon EL13A-2.

There are flashers specifically for LED lights that will operate with
the light (no pun intended) load of LEDs. They are used on cars and
motorcycles, particularly when incandescent lamps are replaced with LEDs.
One of the reasons for installing LEDs is that they draw much less
current. Another is that the run very cool. Adding a resistor across
them defeats the purposes and the advantage is gone. The resistor has
to sink the current that an incandescent bulb would draw. This creates
heat just as it does when the incandescent bulb is lit.
I consider the resistor to be a jury rigged cure that is best dealt with
by using the correct components.
