I purchased the B&C wig wag relay and wired it according to the 

schematic for an off-on-on switch and B&C diode assembly. The 

wig-wag is in the middle position. I included the resistors  between 

the relay and ground shown in the updated schematic. The system 

works fine with incandecent nav lights but not with the LED landing 

lights. Only one LED light turns on in wig wag mode and both lights 

turn on in continuous on mode. The nav lights draw about 3.2 amps, 

the LED lights about 3.7 amp. Anyone know what is going on here and 

how to fix it. Should I just purchase an electronic wig wag unit 

designed for LED's?


	


    I modified that drawing for B&C based on testing I

    did using one of the flashers from their inventory.

    The resistors were added to emulate the fixed load

    offered by incandescent lamps. You are the second

    individual who was unable to duplicate the behavior

    I was getting on the bench. I have a pair of Whelen

    LED landing lights loaned to me by another reader

    and I plotted their current draw vs. voltage curve

    which I posted on the List a few days ago.



    I'm somewhat tied up with some family matters and

    can't get back to the bench right now to figure out

    what's going on  . . . but the solution will not

    be difficult. Sit tight for the moment . . . watch

    this space.

Hi Bob,



I received the updated wiring diagram from B&C that has the 2W 75 ohm resister across the light terminals. I gave it a try and had the same result. Any idea what is going on? Are the Aeroled lights different than the Whelens I saw in the picture?
