No-Load Voltage Adjustment: BeG 6.5KW
1. Remove the louvered metal plate covering the terminal connections and the capacitor (see page 61).
2. Start the generator and allow
tt
to run for approximately five minutes so the engine can warm 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. Referring to the AC load connections diagram below, check the generator's no-load voltage by measur-
ing the voltage across the neutral lead and the hot lead with a volt meter. Make sure you record this read-
ing. 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. Refer to the illustration on the top of the next page.
~WARNINGI
DO NOT attempt to make a no-load voltage adjustment while the generator is operating. The
capacitor can hold a 450 volt charge. Touching any wiring can result in a severe electrical
shock. In addition, attempting to make a no-load voltage adjustment while the generator is
operating can cause fingers to be caught in the generator's rotor.
5. Refer to the illustrations on the next page before making any adjustments. Note that there are three plugs
grouped for the right capacitor terminal, #7, #8, and #9. If the generator's no-load voltage is low, then
disconnect the lower numbered plug and connect the plug with the next higher number. If the generator'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 terminal, or the voltage needs to be lowered and
the lowest numbered plug is connected, then follow the steps listed at the bottom of the next page. Ask
your local Westerbeke dealer for a BC GENERAL TROUBLESHOOTING GUIDE before performing the
steps listed at the bottom
01
the next page.
NOTE: Make sure the insulating covers on the unused leads are in place and are not
in con-
tact with each other or in contact with the generator's housing.
