Alternator
CAUTION
When testing the alternator circuit (charging circuit),
do
not use a high-voltage tester such as
a megger; damaged diodes could result.
During high-speed operation
of
the engine,
do
not disconnect the positive terminal
of
the bat-
tery from the B terminal
of
the alternator, nor disconnect the negative terminal
of
the battery
from the ground. Damage
to
the alternator's diodes will result.
When cleaning the engine with a steam cleaner, be careful to keep steam away from the al-
ternator.
Always connect the battery's cables
to
the correct terminals. Reversing the connections will
damage the DC charging alternator. To connect the battery, connect the
(+)
Positive lead
(Hot) first and then connect the
(-)
Negative lead (Ground) last. To disconnect the battery,
disconnect the
(-)
Negative lead (Ground) first, and then disconnect the
(+)
Positive lead
(Hot) last.
