ELECTRIC SYSTEM - DIAGNOSIS AND TROUBLESHOOTING
● DAMAGE BY HEAT
If the problem in the tractor occurred in hot weather,
the inspector should check the conditions affected by
heat. Apply some heat to the parts with a heat gun to
determine whether such electric parts are sensitive to
heat.
Never let electric parts' temperature rise over 60°C (140
°F).
If a fault occurs while applying the heat, replace the
part or insulate it.

It shouldn't be heated over 60°C.
● FREEZING
A fault may disappear after warming up the tractor (in
cold weather).
In this case, a cause of such fault can be frozen wir-
ing or electric parts. There are two methods to inspect
such fault.
The fi rst method is to ask the customer to park the tractor
outside for over a night to cool it down and reproduce the
symptom and inspect the relevant electric parts rapidly
and thoroughly in the following morning.
The second method is to keep the relevant electric
parts in a refrigerator for enough time to freeze, rein-
stall them and check if such fault is occurred again. If it
is, repair or replace the corresponding part.

● FAULT BY MOISTURE
A fault may occur only in high humidity condition, rainy
season or snow. In this case, a fault may occur when
water enters into electrical parts.
Never spray water directly on the electric parts to re-
produce the symptom.
Inspect the connectors if water enters in it, apply di-
electric grease as needed.

● ELECTRIC LOAD
A fault can occur in electric parts due to the reaction to
electric load. Perform the inspection while turning on
all electric devices (A/C, cigarette lighter, radio, head-
lamps, etc.).
● ENGINE COLD OR HOT CONDITIONS
An electric fault can occur when the engine is cold or
when the engine is hot.
Inspect the tractor after leaving it outdoor over night for
cold condition.
Inspect the tractor after run engine for a while for hot
condition.
