Rapid Wear of Generator Brushes.
POSSIBLE
CAUSES
1) Commutator out-ot-found.
2) Commutator bars out of place.
3) Brushes of improper grade.
REMEDIES
1) Check that maximum
out~of-round
of commutator does not
exceed .0004" (0.01 mm):
-
return commutator on lathe and renew brushes.
2) Check commutator with dial Indicator:
-
renew armature and brushes.
3) Check that brushes are the genuine FIAT type:
-
replace by FIAT brushes.
NOTE
Life of brushes, with generator operating regularly, should range between 25.000 and
37,000 miles (40,000 and 60,000 km).
IMPORTANT
Never insert radio interference suppression condensers of any capacity between:
~
- terminal 67 and ground;
- terminals 67 and 51, both on generator and on' regulator.
If condensers are inserted between said terminals, regulator points will be damaged in a
very short time.
Should interferences occur from regulator, a shielded cable can be used for
«
67)} con-
nection, otherwise replace regulator by a new one.
Nonnally, regulators do not cause radio interference.
If this reconunendation is disregarded, the regulator will be damaged, as explained above.
