Alternator Cable/Fuse Installation Procedure
Always shut off power to the batteries whenever performing any
electrical maintenance or repairs.
Because of heat, vibration, and proximity of other maintenance procedures, you will need to establish
a PM schedule for checking all cable connections in the engine compartment. Inspect cables for dam-
aged heat-shrink tubing, cracking, chafing, or any other kind of damage. Make sure cable connections
are tight and check for broken studs. A suggested interval is given in the Preventive Maintenance chapter
of this manual. Whenever service is performed in the engine compartment, inspect the condition of all
cables and cable connections.
It is critical that correct torque be maintained on jamb nuts, cable
clamping nuts, and all other nuts on the fuse block studs.
When servicing alternator cables and fuses, keep these important tips
in mind:
• Keep cables either vertical or horizontal to prevent interference with
the fuse insulator.
• Never install small wire rings between any large cable lug and fuse.
• Use only stainless steel flat washers, and do not use “star” washers.
• Stainless steel washers should be used only to back up a connection,
and never as a current carrying component.
• Don’t use any washers between the lug and the fuse or between the lug
and the buss bar.
• Make certain that the buss bar and the lug have good contact surface,
and the lug and the fuse have good contact surface as well.
• Always hold lower nut while upper nut is torqued!
• Replace fuses only with fuses of the same amperage. Contact your
Gillig Service representative for the correct fuses.
To install cables and fuses, refer to Figure 9-15 and follow these guidelines:
1. Lightly coat cable connections with copper shield and torque to 140 in-lb.
2. Install buss bar, fuses, clamp, cables, nuts, and washers in the sequence shown. Torque to
140 in-lb.
