3807224 Volvo.Penta Crankshaft, classified

The engine cranks but the engine does not start.
Check the engine fuel system.
Crank the engine.
Observe the action of the fuel rack, the governor, and the air inlet valve.
If a 2301A Electric Governor is installed, measure the voltage that is supplied to the governor. Result
The fuel rack and the governor move in the FUEL ON direction.The problem is in the engine or in the fuel system. Refer to the engine Service Manual. STOP.
The fuel rack does not move. The governor does not move in the FUEL ON direction.The start/stop switch is not in the START position. Go to Step 2.
A 2301A Electric Governor is installed and the supply voltage is greater than 15 volts.The problem is in the governor or the actuator system. Refer to the 2301A Electric Governor Service Manual, SENR3585. STOP.
A 2301A Electric Governor is installed and the supply voltage is less than 15 volts.The problem is in the wiring to the 2301A Electric Governor. Go to Step 3.
Check the slave relay (SR1) and the fuel solenoid.
Connect a jumper with a 20 amp capacity between terminals (TS-11) and (TS-30) of the junction box.
Reset the circuit breaker (CB7).
Crank the engine. Stop the engine with the emergency stop switch if trouble occurs.
Measure the voltage at terminal (TS-11).
Remove the jumper when the test is completed. Result
The engine starts and the engine runs.The slave relay (SR1) is not energizing the shutoff solenoid. Go to Step 3.
The engine does not start.The shutoff solenoid is stuck or the fuel rack is stuck in the shutoff position. Find the source of the problem and correct the source of the problem. STOP.
The engine does not start. The voltage at terminal (TS-11) is zero.The circuit breaker (CB7) is open. Reset the circuit breaker or replace the circuit breaker.
Check the slave relay (SR1).
Connect a jumper between terminals (TS-12) and (TS-24) of the junction box.
Reset the circuit breaker (CB5).
Crank the engine. Stop the engine with the emergency stop switch, if trouble occurs.
Measure the voltage at terminal (TS-24).
Remove the jumper when the test is completed. Result
The engine starts and the engine runs.The (SR1) is not faulty. Go to Step 4.
The engine does not start.Contacts (SR1-30) and (SR1-87) of (SR1) that are normally open have been shorted and the fuel shutoff solenoid is energized. If a 2301A Electric Governor is installed, contacts (SR-30) and (SR-87a) of (SR1) that are normally closed are open or the wiring to the 2301A Electric Governor is faulty. Replace the (SR1) or repair the wiring problem. Refer to Testing and Adjusting, "Slave Relay Test". Reconnect the wire at the terminal of the time delay relay (TD-7). STOP.
The engine does not start. The voltage at terminal (TS-24) is zero.The circuit breaker (CB5) is open. Reset the circuit breaker or replace the circuit breaker. If the circuit breaker is tripped, the (SR1) is shorted. Repair the (SR1) or repair the wiring. STOP.
Check the slave relay (SR2), the start/stop switch, and the water temperature contactor switch (WTS).
Connect a jumper between terminals (TS-2) and (TS-3) of the junction box.
Ensure that the emergency stop switch (ES) is reset.
Ensure that the start/stop switch is in the RUN position.
If a remote normal start/stop switch (RNSS) is not installed, ensure that there are jumpers between the terminals. There are two jumpers. One jumper is between terminals (TS-3) and (TS-4). The second jumper is between terminals (TS-4) and (TS-5).
Crank the engine.
Remove the jumpers when the test is completed. Result
The engine starts and the engine runs.The problem is in the WTS. STOP.
The engine does not start.Check the slave relay (SR2). Refer to Testing and Adjusting, "Slave Relay Test". Replace the faulty relay. If the relay is not faulty, go to Step 5.
Check the start/stop switch and the emergency stop switch (ES).
Measure the voltage at terminal (SR2-30) or at terminal (SSS-4), before you crank the engine and while you crank the engine. Result
The voltage at terminal (SR2-30) is 15 volts or more before you crank the engine.The start/stop switch is not opening when the switch is in the STOP position. The (SR2) is not resetting. Replace the start/stop switch. Ensure that the start/stop switch is in the STOP position before you crank the engine. STOP.
The voltage at terminal (SR2-30) is zero before you crank the engine, and the voltage is 10 volts or more while you crank the engine.Go to Step 6.
The voltage at terminal (SR2-30) is zero before you crank the engine and while you crank the engine.Go to Step 7. The ES or the start/stop switch is not closing.
Check the slave relay (SR2) and the oil pressure switch (OPS1).
Connect a jumper between terminals (TS-24) of the junction box and terminal (SR2-30) of the slave relay.
Measure the voltage at terminals (TS-6), (TS-9), and (TS-12) of the junction box.
Remove the jumper after the test is completed. Result
The voltage at terminal (TS-9) is 15 volts or more.(OPS1) is shorted or the wiring is not correct.
The voltage at terminal (TS-9) is 15 volts or more and the voltage at terminal (TS-12) is zero volts.(OPS1) is shorted and the diode (D2) is open. Refer to Testing and Adjusting, "Diode Test".
The voltage at terminal (TS-6) is 15 volts or more and the voltage at terminal (TS-9) is zero volts.Contacts (SR2-30) and (SR2-87) are shorted or the (SR2) is not resetting. Go to Step 5. Replace the slave relay. Refer to Testing and Adjusting, "Slave Relay Test".
None of the above situations exist.Replace the diode (D2) and crank the engine again.
Check the emergency stop switch (ES) and the start/stop switch.
Connect a jumper between terminals (ES-1) and (ES-2) of the ES. The jumper can also be connected between terminals (SSS-4) and (SSS-5) of the start/stop switch or between terminals (TS-4) and (TS-5) of the junction box if a remote normal start/stop switch (RNSS) is installed. Connect the terminals one at a time.
Measure the voltage at terminal (SR2-30) of the slave relay (SR2) while you crank the engine. Measure the voltage for each switch. Result
