5 LF45/55 series Removal and installation WIRING REPAIR 2-19 6. Compress the contact crimping tool: Do not interrupt the contact crimping before the tool is completely compressed to the end position. Only then is full contact crimping achieved and the tool is opened. 7. Repeat this for the other ends of the buffer connector. 8. Check the contact crimping for damage and pull the wires to ensure they are properly fixed. Note: Improper contact crimping means a bad connection, which may cause failures. Avoid breathing in the vapours produced when heating the crimping insulation. 9. Heat the crimping insulation to fix it properly to the wire insulation. Ensure that the insulation does not get burnt. If the insulation gets burnt it will become brittle and easily break or crack. E501493 2.6 REMOVAL AND INSTALLATION, EARTH WIRE When a failure occurs in an electrical system, one of the first things to be checked is the earth connection, with particular attention being paid to earth connection on the chassis. Points for special attention when checking earth connection on chassis If an earth connection has been removed and is being re-installed, pay attention to the following: - the bolt, nut, earth strip and washers must be cleaned (e.g. using a steel brush or sand paper). If a component is corroded, it must be replaced by a new one. - clean all dirt and paint from the area around the engine/chassis earth connection on both sides of the chassis member so that the bare metal is visible.
