7
Start the engine and run at maximum speed (see
Technical Data
). Meter should show maximum
alternator output in Amps (see
Technical Data
).
Note: The meter reading should be taken as soon as
possible after starting the engine, as the charging current
will fall rapidly.
8
A zero reading indicates failure of the alternator and
may be caused by one of the following conditions.
These are listed in the order of probability.
a
Defective suppression capacitor.
b
Dirty slip rings or worn brushes.
c
Defective regulator.
d
Defective rectifier.
e
Open or short - circuited field (rotor) windings.
f
Open or short - circuited power (stator) windings.
9
To check for fault a, disconnect the capacitor and
repeat the charging test. Renew the capacitor if
necessary.
10
To check for faults b and c, remove the regulator and
brush box assembly. Check the condition of the
brushes and, if necessary, clean the slip rings using
extra-fine glass paper. The regulator may only be
checked by substitution.
11
Faults d, e, and f may be checked only by removing
and dismantling the alternator for further testing.
