Troubleshooting
Troubleshooting can be difficult. The Troubleshooting Index gives a list of possible problems. To make a repair to a problem, make reference to the cause and correction on the pages that follow.This list of problems, causes, and corrections will only give an indication of where a possible problem can be, and what repairs are needed. Normally, more or other repair work is needed beyond the recommendations in the list.Remember that a problem is not normally caused only by one part, but by the relation of one part with other parts. This list is only a guide and cannot give all possible problems and corrections. The serviceman must find the problem and its source, then make the necessary repairs. For each problem, a list of possible causes and corrections is given. The list of probable causes and corrections should be performed in numeric sequence.1.

Probable Cause(s):* Low Or No Battery Voltage* Faulty Switch, Wiring Or Connection In Switch Circuit* Faulty Cable Or Connection (Battery To Starting Motor)* Faulty Starting Motor Solenoid* Faulty Starting Motor* Transmission Problem Prevents Crankshaft From Turning* Inside Problem Prevents Crankshaft From Turning1. Low Or No Battery Voltage Check battery voltage. If battery voltage is less than 8 volts for a 12 volt system, or 16 volts for a 24 volt system, put a charge on the battery. If battery will not hold a charge, load test the battery. Refer to the Electrical System of the Systems Operation, Testing And Adjusting module of this Service Manual.2. Faulty Switch, Wiring Or Connection In Switch Circuit With ignition switch in the "START" position, check voltage at switch connection on starting motor solenoid. If there is no voltage, or if the voltage is low at this connection and there is good voltage at the battery, check for a faulty cable or connection between the battery and the starting motor.3. Faulty Cable Or Connection (Battery To Starting Motor) With ignition switch in the "START" position, check voltage at connection of battery cable to starting motor. If there is no voltage, or if the voltage is low at this connection and there is good voltage at the battery, check for a faulty cable or connection between the battery and the starting motor.4. Faulty Starting Motor Solenoid Remove and repair or replace a solenoid which does not work when voltage is correct at both the battery and ignition switch connections.5. Faulty Starting Motor If the solenoid works and the starting motor does not turn the crankshaft, the starting motor is faulty. Before removing the starting motor, turn the crankshaft by hand to be sure a mechanical failure inside the engine, transmission is not preventing the crankshaft from turning. If the crankshaft turns freely by hand, engage the starting motor again. If the starting motor still will not work, remove the starting motor. Repair or replace the starting motor.6. Transmission Problem Prevents Crankshaft From Turning If the crankshaft cannot be turned by hand, disconnect the transmission. If the crankshaft will now turn, find the cause of the problem in the transmission and make necessary corrections.7. Inside Problem Prevents Crankshaft From Turning If the crankshaft cannot be turned after disconnecting the transmission, remove the spark plugs and check for fluid in the cylinders while turning the crankshaft. If fluid in the cylinders is not the problem, the engine must be disassembled to check for other internal problems. Some of the possible problems are bearing seizure, piston seizure, and valves making contact with the pistons.Engine Hard To Or Will Not Start
Engine Crankshaft Turns Too Slowly
Probable Cause(s):* Low Battery Voltage* Faulty Cable Or Connection (Battery To Starting Motor)* Oil Too Thick For Free Crankshaft Rotation* Faulty Starting Motor* Extra Outside Loads* Mechanical Problem Inside Engine1. Low Battery Voltage Check battery voltage. If battery voltage is less than 8 volts for a 12 volt system, or 16 volts for a 24 volt system, put a charge on the battery. If battery will not hold a charge, load test the battery. Refer to Electrical System of the Systems Operation, Testing And Adjusting module of this Service Manual.2. Faulty Cable Or Connection (Battery To Starting Motor) With ignition switch in the "START" position, check voltage at connection of battery cable to starting motor. If there is no voltage, or if the voltage is low at this connection and there is good voltage at the battery, check for a faulty cable or connection between the battery and the starting motor.3. Oil Too Thick For Free Crankshaft Rotation Use the recommended Lubrication Viscosities as found in the Operation And Maintenance Manual.4. Faulty Starting Motor Remove and test starting motor. Make repairs as necessary or install a new starting motor.5. Extra Outside Loads Damage to the transmission can put extra load on the engine. This prevents free rotation of the crankshaft. To check, disconnect the transmission and start the engine.6. Mechanical Problem Inside Engine Disassemble the engine and check all components for damage.Engine Crankshaft Turns Freely
Exhaust Smoke Can Be Seen While Starting (Go to Step 1) Probable Cause(s):* Cold
