MAINTENANCE AND LUBRICATION
4-7
Electrical System
1. Maintenance of the electrical system consists of
inspection and minor servicing. Any wire, connection
or electrical component showing signs of corrosion,
wear, breakage or unraveling must be repaired or
replaced.
(See Figure 4-2 for electrical wiring
diagram)
2. Frayed or unraveling wire must have the defective
section removed and replaced with wire of the same
color and gauge. Seal all connections and insulate.
3. Corroded terminals must have the corrosion
removed, source of corrosion neutralized and the
terminals resealed, protected, and insulated.
4. Fuse or circuit breaker burn-out or blow-out usually
indicates an electrical short-circuit, although a fuse
can occasionally fail from vibration. Insert a second
fuse or reset the breaker. If this fuse immediately
burns out or the breaker trips, locate the cause of the
electrical short and repair.
5. A light that repeatedly burns-out usually indicates a
loose connection, poor system ground, or a
malfunctioning voltage regulator. Locate the source
of the problem and repair. System grounds must be
grounded to bare metal surfaces. Paint, grease, wax,
and other coatings act as insulators. Replacement
lamps must be equivalent to the factory installed
lamp.
