4. Record the wire connector locations on the contactor being tested for
assembly purposes, and disconnect the harness electrical connectors from
contactor. Check the contactor and the harness connectors for damage or
corrosion and clean or repair as necessary.
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.
5. Measure the resistance across the contactor coil terminals. Resistance of
the coil should be approximately 195 ohms.
6. With the contactor coil not energized, resistance across the contactor main
terminals should be infinite ohms.
7. If testing determines that the main contactor is damaged, ensure that the
battery pack is disconnected and then replace the main contactor.
8. After you complete the main contactor testing, install the battery cover onto
the battery mount. Secure the battery cover with four bolts.
9. Connect the battery pack; refer to Disconnecting and Connecting the Lithium
Battery Pack (page 5–3) .
