My goodness, these are popular. I would like to just make mine light up as I don't have an outside antenna. Never took one of these apart - anyone have a schematic or advice on bringing them back to life? The AC cord on mine was badly frayed so I just cut it off.

I have a service manual. I have to get up into the attic, which is difficult right now, and then I'll scan it if someone doesn't beat me to it first.

I forgot to point out that the lights are controlled by wafer switches in the rotor itself. You'd need to either have a motor rotating a wafer switch or provide an electronic equivalent.

Right. All I did was hard-wire a couple of the lights so when I flip the paddle they light up. Specifically, pins 1 & 2 connected to pin 8.

I got this tidbit from another fourm: http://forums.qrz.com/archive/index.php/t-40067.html

"Pins 1 to 4 connect to switch terminals inside the rotor to light directional lamps in the rotor box. Pins 5 and 6 are for each motor winding; pin 7 is return through a lamp and switch(in the rotor housing) indicating activation, and pin 8 is ground return. This model has no brake."
