, and remove the key; refer to
the Operator's Manual .
2. Disconnect the battery pack; refer to Disconnecting and Connecting the
Lithium Battery Pack (page 5–3) .
3. Remove the four bolts that secures the battery cover to the battery mount.
Remove the battery cover from the machine.
4. Disconnect the machine wire harness connector from the relay. Remove the
relay from the machine for ease of testing.
Note: Prior to taking small resistance readings with a digital multimeter, short
the meter test leads together. The meter will display a small resistance value
(usually 0.5 ohms or less). This resistance is due to the internal resistance of
the meter and test leads. Subtract this value from the measured value for
the tested component.
