BC GENERATORS TROUBLESHOOTING
NO AC VOLTAGE OUTPUT
EXCITING THE GENERATOR
To quickly determine a short or an open in the main stator
winding, excite the generator with 12 VDC using one exciter
winding group to accomplish this ..
The AC voltage that the generator will produce measured
between the line and neutral during excitation will be very
low.
·
NORMAL AC VOLTAGE DURING 12 VDC EXCITATION:
12 -16 VOLTS AC

EXCITING PROCEDURE
Locate one of the exciter winding groups in the generator.
Unplug all connections from both capacitors. Connect 12
VDC across the winding using the winding end connection,
Winding group between #50Hz and
#9.
