Figure 8-14. Chalky White Deposits.
Chalky White Deposits: Chalky white deposits indi-
cate overheating. This condition is usually accom-
panied by excessive gap erosion. A clogged grass
screen, clogged cooling fins and excessively lean
carburetion are some causes of overheating.
Alternator Operation
There are five different models of alternators used
in the K series of engines. They are rated at 1.25,
3, 1 0, 15 and 30 amperes. The 1 . 25 amp system
is intended for battery charging only. The 3 amp
device is intended for battery charging and light-
ing.
Refer to the wiring diagrams and troubleshooting
guides in this subsection to test and service these
systems. There are no adjustments in these sys-
tems. Replace if faulty.
NOTE: To prevent damage to the electrical system
and components:
a. Make sure the battery polarity is correct. A
negative (-) ground system is used with K se-
ries engines.
b. Disconnect the rectifier-regulator leads and/or
wiring harness plug if electric (arc) welding is
to be done on the equipment powered by the
engine. Disconnect any other electrical acces-
sories that share a common ground with the
engine.
c.
Make sure the stator (AC) leads do not touch.
Shorting them together could permanently
damage the stator.
d. Do not operate the engine with the battery dis-
connected.
NOTE: If a battery has discharged to less than 4
volts, there may not be sufficient power to acti-
vate the rectifier-regulator. If the battery fails to
accept a charge from the alternator, charge it on
a battery charger and reinstall.
