BATTERY CHARGING SYSTEM
NOTE: Observe following guidelines to avoid damage to electrical system and components:
● Make sure battery polarity is correct. A negative (-) ground system is used.
● Disconnect rectifi er-regulator plug and/or wiring harness plug before doing any electric welding on equipment
powered by engine. Disconnect all other electrical accessories in common ground with engine.
● Prevent stator (AC) leads from touching or shorting while engine is running. This could damage stator.
Most engines are equipped with either a 9 or 15 amp, regulated battery charging system. Some have a 3 amp,
regulated system with a 70 watt lighting circuit.
