I fitted 2 new position indicators as the last two I had somehow shorted out and fused them while trying to hook up a flap positioning unit (Have since gotten rid of this). I want complete control of the flaps so jut have a rocker switch in the panel. So connected the flap indicator and the trim indicator, soldered joints, connect the left wing flap, file out the flap rod hole a fraction more (Just hitting the airframe) power up the panel and yes everything works as it should. Trim indicator working great as well.
