16-20 ELECTRICAL SYSTEM
Precautions
There are a number of important precautions that are
musts when servicing electrical systems. Learn and ob-
serve a
ll the rules below.
○
Do not reverse the battery lead connections. This will
burn out the diodes on the electrical parts.
○
Alway
s 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 e
lectrical 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 pr
event 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.
○
Bec
ause 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 wind-
ing
s.
○
Take care not to short the leads that are directly con-
nected to the battery positive (+) terminal to the chassis
gr
ound.
○
Troubles m ay involve one or in some cases all items.
Never replace a defective part without determining what
CA
USED the failure. If the failure was caused by some
other item or items, they must be repaired or r eplaced, or
the new replacement will soon fail again.
○
M
ake sure all connectors in the circuit are clean and tight,
and exam ine wires for signs of burning, fraying, etc. Poor
wires and bad connections will affect electrical system op-
e
ration.
○
Measure coil and winding resistance when the part is cold
(at room temperature).
