    The room where it happened
    Reed switch, it "counts" the revolutions of the front wheel and passes that info onto the turn signal self-canceller unit, so that the self-canceller can know how far the bike has travelled down the road and whether it's proper to automatically cancel the signal flashing or not...…..

    Some further info:

    The SELF-CANCELLER UNIT is a rectangular, sealed, rubber-coated box with 6 wires coming out of it into a connector: a solid tan wire, two (2) white wires with a green tracer stripe, a yellow wire with a green tracer stripe, a yellow wire with a red tracer stripe, and a white wire with a red tracer stripe.

    By the way, the self-canceller operates off both time AND distance measurements to determine when it should cancel the flashers.....a minimum of 10 seconds time and 150 meters (about 400 feet) distance. BOTH criteria must be met before the canceller releases the signal flasher:

    http://www.xjbikes.com/forums/threads/help-with-automatic-cancel.81440/


    NOTE: the signal system is designed so that it will still operate if the self-canceller module fails; of course, in such a situation, you will have to cancel the signals manually (by pushing straight “in” on the thumb lever after it has returned to the center position). To diagnose problems with your signal system, you should follow these steps:

    1) unplug the self-canceller from the main harness.
    2) identify the following wire on the main harness side of the plug: white with green tracer stripe wire and the solid black wire.
    3) using a volt/ohm meter set on the ohms x 100 range, probe those two wires and then spin the front wheel. The ohms reading should shuttle back and forth between 0 and infinity
    4) if the above is good, now identify the yellow with red tracer stripe wire. Hook one lead of your ohm meter to it, and the other to a good chassis grounding point. Now, with the flasher switch on the handlebars OFF (center position), the meter should read infinity. With the lever moved to either the left or right signal engagement position, the ohm meter should read 0 ohms.

    If the signals work properly when the self-canceller is disconnected from the system, then you know that the flasher relay, the bulbs, and the handlebar switch circuit (inside the control switch on the handlebars) is okay. If the signals won't operate properly, even with the self-canceller removed from the system, then it may be a problem within your control switch itself, the flasher relay, the signal bulbs, wiring, etc. The movement of the thumb lever fully to one side, AND THEN RELEASING THE LEVER, should:

    a) allow the lever to return to center, and
    b) keep the turn signals ON (flashing) in whichever direction you had chosen, until either:

    i) the self-canceller, if plugged in the system, cancels the flashers, or......
    ii) if the self-canceller is un-plugged from the system, then the flasher will not cancel until you push "in" on the lever, while the lever is in the center position.


    Having to hold the lever fully over to the left or right position is an indication that the internal contacts (within the switch housing) may be wonky. There is a "two-armed" contact that can get bent, or, the slider contacts may have gotten dirty and/or the solder connections to the slider contacts have broken or become loose:

    and

    http://www.xjbikes.com/forums/threads/electrical-challenges.53983/page-2

    The first link above has a good image of the copper contact "arms" that can get bent, and will thus no longer make contact with the brass "button" contact on the bottom of the pivoting lever arm (one button contact on each side of the lever arm), while the second link has some good images of the slider assembly.
