ELECTRICAL SYSTEM
Precautions
There are a number of important precautions that are musts
when servicing electrical systems. Learn and observe all the rules
below.
○
Do not reverse the battery lead connections. This will burn out
the diodes in the electrical parts.
○
Always check battery condition before condemning other parts of
an electrical system. A fully charged battery is a must for
conducting accurate electrical system tests.
○
The electrical parts should never be struck sharply, as with a
hammer, or allowed to fall on a hard surface. Such a shock to the
parts can damage them.
○
To prevent damage to electrical parts, do not disconnect the
battery leads or any other electrical connections when the ignition
switch is on, or while the engine is running.
○
Because of the large amount of current, never keep the starter
button pushed when the starter motor will not turn over, or the
current may burn out the starter motor windings.
○
Do not use a illumination bulb rated for other than the voltage or
wattage specified in the wiring diagram, as the handle cover
could be warped by excessive heat radiated from the bulb.
○
Troubles may involve one or in some cases all items. Never
replace a defective part without determining what CAUSED the
failure. If the failure was caused by some other item or items,
they too must be repaired or replaced, or the new replacement
will soon fail again.
○
Make sure all connectors in the circuit are clean and tight, and
examine wires for signs of burning, fraying, etc. poor wires and
bad connections will affect electrical system operation.
○
Measure coil and winding resistance when the part is cold (at
room temperature).
