    I have an 06 Ultra w/ SE Active Exh and the servo motor has quite working. I have checked the wiring harness and servo cable. Nothing seemed out of place. Anyone have some idea?:banghead:

    i would try wiring it streight from a battery to see if it's the motor or the wiring feeding it. see if the motor went bad or the wiring. would be a good idea to incorporate a 15amp fuse when you go fromthe battery :devil:

    Thanks Skull. I'll give that a try. I don't have a wire schematic for it, but will figure it out.:cussing:

    you may have seen this before, but a factory service manual IS the most important tool in the box, and will pay for itself the first time you need it......................like now!!!!.............:)

    Have to agree, one of the wires going to the servo is power, one is a ground

    Take a meter, disconnect the harness at the pipe, turn on power, put the meter on the power wire and to a good ground, have someone press the button to change the pipes, see if you get power.

    If you have power that would confirm the switch is working, if no power you need to follow the wires back to the next connection, fuse etc to see why you don't have power, could be a bad switch, fuse, connection etc.

    If you have power, then the problem is probably in the pipes servo motor

    At that point you should make up a wire to run from the pos on the battery with a 15 or 20 amp inline fuse so you don't blow things up electronically.

    Run that wire to the servo motor connection wire on the positive side, you may have to ground out the motor, depends on the wires in the harness, if you have two wires one is usually a ground.

    If you have one wire then the motor is ground to the bike through the pipes, my guess is you have two wires.

    If the motor runs and moves things you might have a bad ground in the wire harness, bad relay, etc.

    If it doesn run then you've probably got a toasted servo motor. depends on what's in that area.

    Basically check each circut connection from the switch to the pipe.

    The SE Active works this way: when cruising 1/3 throttle, the butterfly in the left bank is open, when you twist the grip, the ECM gives the servo a message to close, causing a 2 into 1 pipe situation. You have the best of both worlds when it works properly. A 2 into 2 pipe or a 2 into 1 pipe. I hope I have explained this OK. Thanks for all your advice. I will look into all.

    old mother harley seems to be one step ahead, only way to win is to do our own work and learn, but it's a long and bumpy road, that only a true biker can endure:devil:
