PROBLEM
Battery voltage gets
too high.
Batteries do not reach
full state of charge.
Rotor turns, but the
system doesn't charge
the batteries.
CAUSE(S)
PowerCenter regulating
voltage set too high or
no dump load being
used.
PowerCenter regulating
voltage set too low.
Loads are too large.
Open circuit breaker.
Blow output fuse.
Power transistor failure.
Turbine rectifier failure.
DIAGNOSIS
Excessive battery gas-
sing. Use voltmeter to
check battery cell volt-
ages or hydrometer to
check the specific grav-
ity – compare to battery
manufacturers recom-
mendations.
Use hydrometer to
check the specific grav-
ity of the battery cells.
Compare with battery
manufacturer's recom-
mendation.
Remove largest load. If
battery bank reaches
higher state of charge,
then the system is over-
loaded.
Check circuit breaker on
the side of the Power-
Center.
No lights on PowerCen-
ter.
Turbine voltage is
above 10 VDC and Tur-
bine light is on, but no
current is being deliv-
ered.
Check voltage from the
turbine.
REMEDY
Contact the BWC Ser-
vice Department for the
voltage regulation set-
point adjustment proce-
dure.
Contact the BWC Ser-
vice Department for the

point adjustment proce-
dure.
Consult with BWC about
possible remedies.
Switch to "On"
Replace 90A battery
fuse on PowerCenter
circuit board.
Return complete Pow-
erCenter to BWC for
repair.
Replace rectifier as-
sembly.
