The kill switch (or engine cutoff/cutout switch) is a toggle switch on the right handlebar switch assembly prevents motor operation as a separate control from other interlocks.

Mounting

On the right handlebar switch assembly.

Operation

Push up/forward to cutoff motor operation.

Push down to enable motor operation.

When to Cutoff Motor Operation

• Whenever the bike should not be operating.

  This is a redundant safety mechanism to prevent injury or damage.

• If the vehicle is on its side after a crash or other incident.

  This prevents spinning up the wheel.

• Whenever someone unfamiliar with the motorcycle is sitting on it or nearby.

  If they intentionally or unintentionally touch the throttle, this prevents their lack of familiarity from causing a surprise excursion.

Troubleshooting

The status command in the MBB console can report its reading.

While energized, a voltmeter will indicate 5V across the input leads if the switch is open, and 0V if shut.

While de-energized (and confirmed), resistance across the switch will be high if open, and low if shut.

Connections (Gen2)

It is wired as a digital input to the MBB.

SPST where the off position is an open circuit, for failsafe considerations.

Red 20AWG - (assumed high/positive-5V) to MBB pin 23 (per 2013 trace)

White 20AWG - (assumed low/0V) to MBB pin 24 (per 2013 trace)
