PROBLEM CAUSE(S) DIAGNOSIS REMEDY

Battery voltage gets
too high.

PowerCenter regulating
voltage set too high or
no dump load being
used.

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.

Contact the BWC Ser-
vice Department for the
voltage regulation set-
point adjustment proce-
dure.

Batteries do not reach
full state of charge.

PowerCenter regulating
voltage set too low.

Use hydrometer to
check the specific grav-
ity of the battery cells.
Compare with battery
manufacturer’s recom-
mendation.

Contact the BWC Ser-
vice Department for the
voltage regulation set-
point adjustment proce-
dure.

Loads are too large.

Remove largest load. If
battery bank reaches
higher state of charge,
then the system is over-
loaded.

Consult with BWC about
possible remedies.

Rotor turns, but the
system doesn’t charge
the batteries.

Open circuit breaker.

Check circuit breaker on
the side of the Power-
Center.

Switch to “On”

Blow output fuse.

No lights on PowerCen-
ter.

Replace 90A battery
fuse on PowerCenter
circuit board.

Power transistor failure.

Turbine voltage is
above 10 VDC and Tur-
bine light is on, but no
current is being deliv-
ered.

Return complete Pow-
erCenter to BWC for
repair.

Turbine rectifier failure.

Check voltage from the
turbine.

Replace rectifier as-
sembly.
