Could it be that this is creating a pulsating drain which you are seeing as a periodic fluctuation in bus voltage? Electrically, the aircraft is quite basic. Originally it was supplied with a Narco MK 12 with the tube/power supply unit located in, if I remember correctly, way aft in the tail cone. The clipper had a gyro inst rument panel. I actually got my instrument rating in it in 1969. check the draw of the beacon. Rich In a message dated 10/19/2015 1:23:14 P.M.

Now trying to run it in the UK it keeps overheating and popping the thermal cut-out. I guess a new motor is on the cards...
