DELCO REMY 21-SI 200 GENERATOR
6P1 -2 21 -SI 200 GENERATOR
GENERAL DESCRIPTION
This generator has a solid-state regulator with a ,
two-terminal connector mounted inside the slip ring end
frame (figure 1). The voltage regulator is not adjustable:
This generator, is equipped with.an “R” terminal to oper
ate auxiliary equipment. On some 21-SI models, the
The rptoiri bearings Contain enough grease to elimi
nate periodic lubrication. Two brushes carry current
through two slip rings to the field coil.
The Stator windings are assembled on the inside of a
laminated core that forms parf of the generator frame. A
rectifier bridge connected to the stator windings contain
six diodes,; , and electrically changes the stator AC volt
ages to DC voltage that appears at the generator output
“BAT” terminal. Generator field current is supplied
through a diode trio connected to the stator windings. A
capacitor mounted to the end frame protects the rectifi
er bridge and diode trio from, high voltages, and sup
presses'radio noise.
The generator part number is stamped in the housing
behind a mounting flange.
GENERATOR OUTPUT TEST
to check the generator in a test stand, make the
connections! as shown in figure 4. Use a 10 - 50 ohm
resistor.
;
1. With the carbon pile off, make connections as
shown.
• The ground polarity of the battery and the gen
erator must be the same.
• Use a fully charged battery in this test.
2. Reestablish rotor magnetism if the generator has
