General Rules Trouble Shooting
I. Appearance inspection before repair
1. Check for relevant fuses and relays.
2. Check for possible damage, charging state, surface cleanness and harness interface tightening
of battery;
Notes:
(1) When the battery has a loose earth connection, do not attempt to start up the engine, or the
connection will be seriously damaged.
(2) If the earth connection is not disconnected, quick charge is forbidden, otherwise damage will
bring to diodes of AC generator.
3. Check for belt tightness of AC generator;
II. Operating condition of harness interface
1. Clean and tight interface terminal.
2. All interfaces equipped with pushing separated latch fitting (A). (Fig. 4-1)

3. Some interfaces have clips for fixing the interface onto the vehicle body or other assembly,
noted that the clips secure through reverse buckling.
4. Some interfaces are equipped with double self-locking, which must be unlocked before
removing the interface from its mount (A).
5. To separate interfaces, pulling the harness should be avoided, instead, grab the interface (for
the ones with self-locking, unlocking is required) to remove it from the mount (A). (Fig. 4-2)
