If anyone has an AC4 supply open, please tell me where the red/white wire goes to. One end of it connects to a faded orange or yellow wire at a terminal strip and the orange wire goes to pin 10 of the power plug. The other end of the Red/White wire goes somewhere around the H.V. caps but I don't know where it attaches. If you know or can determine, please advise. Thanks and 73, john, K5PGW
