ELECTRICAL SYSTEM AND COMPONENTS
Worn: On a worn plug, the center electrode will be rounded
and the gap will be eroded .010" or more than the correct
gap. Replace a wom spark plug immediately.
the combustion chamber. Excess fuel could be caused by
operating the engine with too much choke. Oil in the com-
bustion chamber is usually caused by worn piston rings or
valve guides.
*NOTE: For repeated spark plug fouling, order and
install Carburetor Baffle Kit 82 755 24.
Chalky White Deposits: Chatky white colored deposits indi-
cate overheating. This condition is usually accompanied by
excessive gap erosion. A clogged grass screen, clogged
cooling fins, and lean carburetion are some causes of
overheating.

BATTERY CHARGING SYSTEMS
The following battery charging systems are available
on Magnum twin cylinder engines.
D 15 Amp Regulated Battery Charging System
O 25 Amp Regulated Battery Charging System
Refer to the following wiring diagrams and trouble-
shooting guides to test and service these battery
charging systems.
NOTE: To prevent damage to the electrical system
and components:
1. Make sure battery polarity is correct. A nega-
tive (-) ground system is used.
2. Disconnect the rectifier-regulator leads and/or
wiring hamess plug before electric welding is
done on the equipment powered by the en-
gine. Also disconnect other electrical acces-
sories in common ground with the engine.
3. Prevent the stator (AC) leads from touching or
shorting while engine is running. This could
permanently damage the stator.
