    The best way? Replace the switch.

    The OK-for-now-way. Twist the wires together and cover it with electrical tape.

    The I-do-not-care-about-no-stinking-safety way. Remove the sidestand switch relay.

    Sidestand (kickstand) Relay:

    Location:
    - on all XJ550 models: left side, onto a welded bracket just behind the rear frame cross tube.
    - on all 1982-84 XJ650 Maxim models: onto a welded bracket outbound of the left outer frame tube, just behind the left coil.
    - on all XJ650RJ Seca models: under the front of the tank, behind the turn signal flasher relay.
    - on all XJ650 Turbo models: on a tab bracket welded to the right frame down tube, below the airbox.
    - on all XJ700 and XJ750-X models: under the left frame side cover, on the plastic regulator-rectifier mounting plate.
    - on all 1981-83 XJ750 Seca models: onto a welded bracket outbound of the left outer frame tube, just behind the left coil.
    - on all 1982-84 XJ750 Maxim/Midnight Maxim models: under the left frame side cover, on the plastic regulator-rectifier mounting plate.
    - on all XJ900 models: under the seat, in the "electrical tray".
    - on all XJ1100 models: under the fuel tank, behind the left side ignition coil.

    Identification:
    - small metal (original) or plastic (replacement) "cube" relay, inked 4U8-00, 4U8-01, or 4U8-02 on the top face.
    - has a blue paint mark or blue locking tab shroud on the bottom of it.
    - normally closed; does not have an internal diode.
    - plugs into a connector shell which has the following set of wires going to it:

    Harness connector wire colors:
    - on all XJ550, all 1982-84 XJ650, XJ700, XJ750 models, all XJ900, and XJ1100 models:
    * Red wire with white tracer stripe
    * Black wire with white tracer stripe
    * Blue wire with yellow tracer stripe
    * solid Black wire

    You can do either. Jumpering the switch wires completes the circuit that allows the ignition to be on when in gear with the clutch out. Removing the sidestand relay accomplishes the same thing.

    If the circuit is not completed (as if the sidestand were down), you can start the bike in neutral, or start the bike in gear with the clutch pulled in, but the moment you try to pull away the ignition will be cut and the engine will die.

    If you battery is marginal, sometimes turn signals come on, but only blink when engine is running/charging.

    Another check - make sure you have 27w bulbs in the turn signals, not 23w bulbs. The lower wattage sometimes mimics the same problem as a low battery, at least it did on mine.

    Check the above. If that doesn't fix it, it may be the turn signal relay/blinker needs attention.

    If you want to keep the switch can it be repaired or do you have to replace it? Mine works most of the time. Then randomly doesn't.

    The switches are encased in epoxy. If regular cleaning won't keep it working, then it has to be replaced.
    Make sure that the switch is at fault and not the relay or a wiring issue.
    Do you have a multi-meter?

    I do have a meter. It seems to be working more than not. Is it a three wire switch. With NO and NC contacts?

    2-wire. Black and Blue with a yellow trace. Normally closed.

    I haven't noticed but if it's Normally Closed then the stand presses it to open...Is that true? I thought it was NO so the stand closed it by pressing it...

    The switch runs a relay that closes when the ignition is turned on. It is a normaly closed switch, otherwise the relay would only close (and power the TCI) with the sidestand down.

    It depends on the model whether it is a two or three wire. The XJ's with the computer monitoring use the 3 wire DPST switch, one switch for the computer, and one for the side stand safety.

    It is easy to get confused here, but the switch would be considered normally closed as the actuator is in the depressed condition with the side stand down and the switch is in an open state. The side stand relay will be energized by the closed neutral switch when the bike is in neutral allowing it to start. The side stand must then be put up releasing the actuator to close the switch so the side stand relay remains energized when the bike is put in gear and the neutral switch opens.

    So you can just bypass the relay, without worrying about the Bike locking you out, or some non-sense?

    You can do that, but then you risk driving off with the sidestand down (this is what the switch/relay is supposed to prevent), and the first time you make a left hand turn with the sidestand down, your next memory may be waking up in the ER......even at relatively low spees (15 mph)

    you should fix it.
    ok got that out of the way

    you can pull the relay untill you fix switch or just unplug the black and white wire at the tci.

    the switch keeps you from riding away with your stand down . makes a difficult left turn.

    Cleaning the sidestand switch is easy. They rarely actually fail.
    Remove the rubber boot from the switch housing. Spray contact cleaner onto the switch plunger as you work int in and out manually. Once it moves freely follow up with a dry-film lubricant. Replace the rubber boot. Do that annually (semi-anually if you ride on dirt often).
