PROCEDURE
DANGER
Park vehicle safely, apply parking brake, stop engine. Prior to working on the vehicle, set the ignition
switch to the OFF position and trip the main circuit breakers equipped with a trip button. On Commuter
type vehicles, set the battery master switch (master cut-out) to the OFF position.
POWER CABLES GENERAL INSPECTION CRITERIA
1. Make sure that the power cables are properly secured with appropriate fasteners so that they
do not move. Movement of the cables can cause wear of the extruded protective sheath,
strains on stud terminals and ring cable lugs.
2. Ensure that the power cables do not rub on other cables or other components.
3. Make sure ring cable lugs are securely attached to the stud terminals, that the retaining nut is
tightened. Also, make sure that cable lug crimping holds firmly on copper conductor.
OTHER THINGS TO CHECK
Check for damages caused by electric arcs with loss of material along the copper conductor.
•
• Check for damaged cable extruded sheath and having lost its insulating properties.
• Bosch T1 alternator: ensure that the rubber grommets at the rear cap of the alternator are present.
• P-clamp type cable clamps must be suitable for cable diameter. The cable must remain in the P-clamp
without moving or rubbing, thus oversized P-clamps are not allowed. Inspect the corrugated protective
sheath passing through the P-clamp for signs of wear.
• At certain locations, power cables are protected by a corrugated protective sheath and should remain
as such.

Ensure that the power cables do not rub on bolt heads or sharp metal edges that can cut or wear the
•
cable extruded sheath.
