CAUTlON WITH ELECTRICAL PARTS
Battery Cable
Before disconnecting connectors or replacing electrical parts,
disconne@ the negative battery cable.
Connectors
Removal of connector
Never pull on the wiring harness when disconnecting con-
nectars.
Connectors can be removed by pressing or pulling the lock
lever as shown.
Locking of connector
When locking connectors, make sure to listen for a click that
will indicate they are securely locked.
Inspection
1. When a tester is used to check for continuity or to measure
voltage, insert the tester probe from the wire harness side.

2. Check the terminals of waterproof connectors from the con-
nector side, as they cannot be accessed from the wire har-
ness side.
Caution l
Use fine wire to prevent damage to the terminal. l
Do not damage the terminal when inserting the
tester lead.
Terminals
Inspection
Pull lightly on individual wires to check that they are secured
in the terminal.
Replacement of terminals
Use the appropriate tools to remove the terminal as shown.
When installing the terminal, be sure to insert it until it locks
securely.
Insert a thin piece of metal from the terminal side of the con-
nector, and then, with the terminal locking tab pressed down,
pull the terminal out from the connector.
