My 153I controller always seems to turn my accessories on, no matter how I adjust the controls. I'm flying blind here, as I bought it at a flea market with no instruction sheet. I've connected the power to the "A" and "U" sockets, plugged in the accessory to the "ACC PWR" and the "ACC GND" sockets. I also have no idea what the "NO" and "NC" sockets are for which are next to the "ACC PWR" and the "ACC GND" sockets. What am I doing wrong?
