18.4) Lighting circuit:
In the stator 8 lighting coils are incorporated. The output is 170W A.C. at
6000 l/min. This alternating current can be used directly to feed A.C.
consumers, or via a rectifier-regulator for loading a battery and feeding
direct current consumers.
To avoid the voltage to rise above permissible levels, a voltage regulator
must be used.
To operate loads requiring direct current (e.g. charging battery), a rectifier-
regulator is required.
A rectifier-regulator, part no. 866 080, is available. As a power supply for
lights only. This rectifier-regulator can be used without a battery. In this
case the regulated RMS voltage will be between 11 and 12 Volts as long
as a minimum load of 1 amp is provided.
If a battery is used it must be capable of absorbing approx. 1 amp. minimum
continuous charging load, even with full charge (suggested minimum
battery capacity: 9 amp.h, resp. 16 amp.h with electric starter). Regulated
voltage is 13.5 to 14.5 volts.
When using 3-phase rectifier-regulator 264 870 no minimum load is
required.

18.5.1) Wiring diagram for rectifier regulator 866 080
■ Attention: To avoid excessive voltage in conjunction
with the rectifier regulator 866080, a con-
stant minimum ballast load of 1 amp is re-
quired (example: lamp 12 V 15 W).
