Problem 2
The engine does not crank.
Check the engine mounted start switch (EMSS).
Ensure that the emergency stop switch (ES) has been reset.
Place a switch across the terminals of the EMSS.
Close the switch momentarily, but do not start the engine.
Remove the switch when the test is completed. Result
The engine cranks.The EMSS is faulty or the circuit breaker (CB2) must be reset.
The engine does not crank.Go to Step 3.
Check the start/stop switch.
Ensure that the emergency stop switch (ES) has been reset.
Connect a switch with a 2 amp capacity between terminals (TS-21) and (TS-26) of the junction box.
Close the switch momentarily, but do not start the engine.
Disconnect the switch after the test is completed. Results
The engine cranks.The start/stop switch is faulty or the wiring to the switch is faulty. Replace the switch or repair the wiring. The circuit breaker (CB2) may need to be reset.
The engine does not crank.Go to Step 3.
Check the emergency stop switch (ES).
Ensure that the emergency stop switch (ES) has been reset.
Connect a switch with a 2 amp capacity between terminals (TS-26) and (TS-24) of the junction box.
Close the switch momentarily but do not start the engine.
Disconnect the switch after the test is completed. Result
The engine cranks.The emergency stop switch (ES) is faulty.
The engine does not crank.Reset the circuit breaker (CB5) and repeat Step 3. If the engine does not crank go to Step 4.
Check the components of the starting system.
Check the voltage at terminal (TS-24) of the junction box. Result
The voltage is low. Low voltage is between 1 volt and 20 volts.Charge the battery or repair the loose connections between the battery cable terminal and the battery. STOP.
The voltage is above 20 volts.The magnetic switch (MS), the pinion solenoid (PS), or the starting motor (SM) is faulty. The circuit breaker (CB2) may need to be reset. Reset the circuit breaker and repair the component that is faulty.
The voltage is zero (less than 1 volt).The circuit breaker (CB5) is being overloaded or the circuit breaker is faulty. Repair the short circuit or replace the circuit breaker. STOP.Problem 3
The engine starts and shutdown occurs immediately, or engine cranking terminates.
Check the protection switches.
Measure the voltage at terminal (SR2-30) while you crank the engine. Result
The voltage is above 10 volts while you crank the engine. The voltage then decreases to zero when the engine shuts down.The emergency stop switch (ES), the water temperature contactor switch (WTS), and the start/stop switch are opening. Check the start/stop switch first. The switch may be open across the common pair of contacts for the START/RUN switch when the switch is in the START position. The switch may also be open when the switch is released from the START position. Go to Step 7 of "Problem 1".
The voltage is above 10 volts at all times.The diode (D2) is faulty or there is a short across the diode circuit. The engine oil pressure switch (OPS1) may also have an intermittent short in the switch or in the connection. Refer
