and be peiformed by a qualified technician.

SINGLE EXCITER NO-LOAD VOLTAGE ADJUSTMENT
1. Remove the louvered metal plate, at the back of the
generator, covering the AC terminal connections and
the capacitor(s).
2. Start the generator and allow it to run for approximately
five minutes so the engine can wann up. Make Sure the
generator is operating without any equipment drawing AC
current from the generator (that is, shut off all electrical
appliances). Make sure the engine's speed (Hertz) is
correct. Adjust the governor as needed to obtain the
correct engine speed before proceeding.
3. Refer to the AC LOAD CONNECTIONS DIAGRAM for
the correct configuration then check the generator's
no-load voltage by measuring the voltage across the neu-
trallead and the hot lead with a volt meter. Make sure you
record this reading. The generator's no-load voltage is
115 - 124 volts at 60.5 - 61.5 Hertz. If the voltage output
is higher or lower than specified, proceed.
4. Shut off the generator. Make sure the correct Hertz lead
(60 Hertz #6, or 50 Hertz #5)
is plugged into the
capacitor(s).
A WARNING: Capacitors must be discharged before
handling as they store electricity and can pack a poten-
tially lethal charge even when disconnected from their
power source.
NOTE: Simply cross the capacitor's two terminals with an
insulated (plastic handle) screwdriver. This will discharge
any excess electricity.

A WARNING: 00 not attempt to make a no-load
voltage adjustment while the generator is operating.
The capacitor can produce a 400-500 volt charge.
Touching any wiring can produce a severe electrical
shock. In addition, attempting to make a no-load volt-
age adjustment while the generator is operating could
cause your fingers to be caught in the generator's rotor.
5. There are three plugs grouped for the capacitor
tenninal, #7, #8, and #9. If the generator's no-load voltage
is low, then disconnect the lower numbered plug and con-
nect the plug with the next higher number. If the genera-
tor's no-load voltage is high, then disconnect the higher
numbered plug and connect the plug with the next lower
number. Note that the plug presently connected to this
terminal may be
anyone of the three plugs available.
6. If the generator's no-load voltage cannot be adjusted
because the voltage needs to be increased and the highest
numbered plug is already connected to the right tenninal,
or the voltage needs to be lowered and the lowest num-
bered plug is connected, refer to the WESTERBEKE BC
