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 need ~14v to actually charge, which the 12v battery can't deliver. On Tue, Aug 9, 2016 at 6:28 AM, Steve Kelly wrote: > > Ok. I think I will give that a try.

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. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=459389#459389 ________________________________ Message 4 _____________________________________ Time: 07:56:53 AM PST US Subject: Re: AeroElectric-List: Re: Battery charging From: Charlie England Try searching ebay; I've seen some pretty good deals there.

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?

If you use them with LED lights, the lights probably don't draw enough current to make the flasher 'switch' between the lights. FWIW....

B&C doesn't seem to carry the flasher anymore but it is still available if you look around for it. Tridon EL13A-2.

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.
