D. Battery Charging Circuit
NOTE: This circuit is totally separate from the AC output of the generator. The AC output of
the generator affects this circuit's output, but not the reverse.
1. Bridge Rectifier
Normal AC voltage to rectifier - (engine operating at 1800 rpm). This voltage is measured across the
two AC connections on the bridge rectifier.
AC Voltage to the bridge rectifier (approximate):
a. No-load off generator - 16.0 volts AC
b. Full-load off generator - 17.5 volts AC
Normal DC voltage out of rectifier - volts DC. This voltage is measured across the two DC connections
of the bridge rectifier,
+
to
+
and - to - .
DC voltage from the rectifier (approximate):
a. No-load off generator -17.0 volts DC
b. Full-load off generator - 18.5 volts DC
2. AC Stator Winding: 0.14 Ohm
Lift the two AC leads off the bridge rectifier and measure with an ohmmeter the resistance value be-
tween these two leads. This measurement should register 0.14 ohm. No continuity should exist be-
tween either of these two leads and the ground.
