Electrical Repair

Wire Harness Repair

1. Peel off 0.5 inch insulating layer from the lead to be repaired and the substitute lead.
2. Connect the original lead to the substitute lead with the heat shrink tube and compress the metal core of 

heat shrink tube with a tool, so that the original lead and the substitute lead can be connected firmly.

3. Heat the heat shrink tube to shrink the outer rubber layer and ensure that the sealing of repaired area is in 

good condition.

4. Wrap the repaired lead with insulating tape.

Fuse Replacement

1. Turn off all the electrical equipment and ignition switch before servicing.
2. Remove the blown fuse with a fuse puller.
3. Replace the fuse with a new one which has the same 

specification.

CAUTION

 Measure the length of lead to be repaired and select a proper substitute lead before servicing.
 If there are several leads to be repaired, please stagger the repaired parts.

CAUTION

 Energizing test should be performed after replacing the fuse. If the fuse is blown again, check the 

corresponding circuit for short. If any electrical equipment or additional device which exceeds the rated 
current is installed, replace it with the fuse with higher amperes.

There are a variety of ways to fix connector clips, and 
common disconnection methods are shown in the 
illustration.

b. Install the connector.

A "click" can be heard when the connector is installed 
in place.

c. Replace the connector terminal.

As shown in the illustration (1), insert a suitable tool 
into the terminal to lift up the fixing clip, and then pull 
out the terminal from behind.
During installation, push the terminal from the back of 
the connector to ensure that the fixing clip is installed 
in place as shown in the illustration (2).

d. Check the connector terminal.

Pull a single wire harness terminal gently to check if it 
is installed in place.
