There are a number of important precautions that are
musts when servicing electrical systems. Learn and
observe all the rules below.
O Do not reverse the battery lead connections. This will
burn out the diodes in the electrical parts.
OAlways check battery condition before condemning
other parts of an electrical system. A fully charged
battery is a must for conducting accurate electrical
system tests.
OThe 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.
OTo 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.
O Because of the large amount of current, never keep the
starter switch pushed when the starter motor will not
turn over, or the current may burn out the starter motor
windings.
0 Do not use a meter illumination bulb rated for other than
voltage or wattage specified in the wiring diagram, as
the meter or gauge panel could be warped by excessive
heat radiated from the bulb.
OTake care not to short the leads that are directly
connected to the battery positive ( + ) terminal to the
chassis ground.
OTroubles 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.
O 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.
0 Measure coil and winding resistance when the part is
cold (at room temperature).
