Work through the checks in order. The check marked most likely is the alarm module, which Metacyclopedia calls extremely troublesome and a frequent source of problems.

01Checks, in order

  1. Make sure the engine kill switch is set to "On".

    pass
    It's on. Continue.
    fail
    Set it to "On" and try again.
  2. Wait a while. If the controller or motor got too hot, everything shuts down as a safety measure.

    pass
    Still dead after cooling. Continue.
    fail
    It powers on once cool. Heat was the cause; ease off until you know why it overheated.
  3. Use the activation dongle, or plug in the charger, so the battery connects internally. Listen for a click.

    pass
    Still dead. Continue.
    fail
    It powers on. The battery needed activating.
  4. Replace the batteries in the key fobs, and check the fob LEDs blink when you press a button (that means they're transmitting).

    pass
    Fobs blink but the bike still doesn't respond. Continue.
    fail
    The bike responds with new batteries. Done.
  5. Check the 5 A blade fuse in the battery compartment.

    pass
    The fuse is good. Continue.
    fail
    It's burned out. Replace it.
  6. most likelyIf the alarm still doesn't chirp when you press the fob buttons, unplug it and bridge the harness's red/white and yellow wires (the alarm's red and orange) under the seat.

    pass
    The bike turns on. The alarm is the fault; replace or bypass it.
    fail
    The bike stays off. The problem isn't the alarm. TODO, next step not documented; ask in the community groups.
