Maintenance
Electrical
Alternator–Starter–Battery Test
An Amps-Volts-Resistance test should be performed periodically
by a trained professional.
The test checks for alternator
amperage output, starter current draw, and battery amperage
capacity. This type of testing detects weaknesses that may not
yet be apparent during normal daily operations.
Terminal Inspection–Cleaning–Corrosion Protection
Periodically, inspect electrical connectors in the battery box,
electrical panel box and engine compartment for corrosion and
tightness. Clean all exposed terminals and apply a lubricant
sealing grease such as Fleetrite
® 472141–C1 or equivalent. The
inspection / cleaning / corrosion protection should include feed
through connections, power and ground cable connections for
batteries, engines and the starter stud.
Inspect exposed cables for fraying or signs of abrasion.
Connectors that are more subject to corrosion may be
disassembled and sprayed with a light coating of dielectric
grease. Use grease sparingly. Too much grease will not allow
air to escape from the connection and this compressed air will
push the connection apart.

WARNING
To prevent personal injury and / or death, or
damage to property, do not increase size of fuse
or circuit breaker or change type of breaker
supplied with your truck, as this could cause
wiring to overheat and possibly burn. Electrical
circuits are designed with a particular wire gauge
to meet the fuse and circuit breaker current
rating.
Vehicle electrical systems are complex and often include
electronic components such as engine and transmission
controls, instrument panels, antilock brakes, etc. While most
systems still operate on battery voltage (12 volts), some
systems can be as high as 90 volts or as low as 5 volts. Refer
to the
Electrical Circuit Diagram Manuals available from IC
Bus to ensure that any additional body lights and accessories
are connected to circuits that are both appropriate and not
overloaded. No modification should be made to any vehicle
control system without first contacting your IC Bus dealer.
