Trouble Remedy
Engine starts, but stops when Start/Pre-
heat switch S1 is released. Check coolant level. Automatic shutdown system stops engine if engine temperature is too high (see Sec-
tions 4-5).
Check timer relay T for proper coil voltage and connections. Check continuity of coil and condition of con-
tacts. Replace timer relay T if necessary.
Check control relay CR1 for proper coil voltage and connections. Check continuity of coil and condition
of contacts. Replace CR1 if necessary.
Engine hard to start in cold weather. Turn Start/Preheat switch S1 to Preheat position before starting (see Section or 5-1).
Check glow plug and related wiring (see engine manual).
Keep battery in good condition. Store battery in warm area off cold surface.
Use fuel formulated for cold weather (diesel fuel can gel in cold weather). Contact local fuel supplier for
fuel information.
Use correct grade oil for cold weather (see Section 7-1).
Engine suddenly stops. Check oil level. Automatic shutdown system stops engine if oil pressure is too low (see Sections 4-5).
Check coolant level. Automatic shutdown system stops engine if engine temperature is too high (see Sec-
tions 4-5).
Check control relay CR2 for proper coil voltage and connections. Check continuity of coil and condition
of contacts. Replace CR2 if necessary.
Check fuel solenoid FS1 for proper coil voltage and connections. Check continuity of coils. Replace
FS1 if necessary.
Engine slowly stopped and cannot be
restarted. Check fuel level.
Check engine air and fuel filters (see Sections 7-3 and 7-6).
See engine manual.
Battery discharges between uses. Clean top of battery with baking soda and water solution; rinse with clear water.
Recharge or replace battery if necessary.
Periodically recharge battery (approximately every 3 months).
Engine uses oil during run-in period;
wetstacking occurs. Dry engine (see Section 13).
