Fig. 10.28 Alternator Removal
7. If previous Steps 1 thru 6 check satisfactory,
check alternator as follows:
(a) Disconnect battery ground cable.
(b) Connect an ammeter in the circuit at the
“BAT” terminal of the alternator.
(c) Connect battery ground cable.
(d) Turn on all electric equipment. Connect a
carbon pile battery tester across the
batteries.
(e) Operate engine at moderate speed as
required, and adjust carbon pile as
required to obtain maximum current
output.
(f) If ampere output is within 10 amperes of
rated output as stamped on alternator
frame, alternator most likely is not defec-
tive; recheck Steps 1 thru 6.
IMPORTANT: If output in amperes is OK, but
indicator lamp stays on, check diode trio and
rectifier bridge in paragraph 10.6.1.f and 10.6.1.g.
(g) If ampere output is not within 10 amperes
of rated output, determine if test hole, Fig.
10.27, is accessible. If accessible go to
Step h. If not go to paragraph l.
(h) Ground the field winding by inserting a
screwdriver into the test hole, Fig. 10.27.
IMPORTANT: Tab is within 3/4 inch of casting
surface. Do not force screwdriver deeper than
one inch into end frame.
(i) Operate engine at moderate speed as
required, and adjust carbon pile as
required to obtain maximum current
output.
(j) If output is within 10 amperes of rated
output, check field winding as covered in
paragraph 10.6.1.e, and test regulator with
an approved regulator tester.
(k) If output is not within 10 amperes of rated
output, check the field winding, diode trio,
rectifier bridge, and stator as covered in
paragraphs 10.6.1.e, f, g and h.
