8637824 Volvo.Penta Cable terminal

The engine cranks but the engine does not start.
Check the engine fuel system.
Crank the engine.
Observe the action of the fuel rack and the governor.
If a 2301A Electric Governor is installed, measure the voltage that is supplied to the governor.Result
The fuel rack and the governor move into 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 was 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 rack.
Disconnect the wire from terminal (TS-30) to the fuel shutoff solenoid (FSOS). The wire is on the terminal strip in the junction box.
Crank the engine. Stop the engine with the emergency stop switch if trouble occurs.
Reconnect the wire when the test is completed.Result
The engine starts and the engine runs.The slave relay (SR1) is 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.
Check the slave relay (SR1).
Disconnect the wire that connects terminal (SR1-85) of the slave relay (SR1) to terminal (TD-7) of the time delay relay. Insulate the end of the removed wire in order to prevent contact with any conductive surfaces.
Crank the engine. Stop the engine with the emergency stop switch, if trouble occurs.
Reconnect the wire 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". STOP.
Check the protection switches and the time delay relay (TD).
Disconnect the jumper between the terminals (TS-9) and (TS-10) of the junction box.
If the engine is equipped with a low oil pressure indicator, disconnect the diode that is between terminals (TS-8) and (TS-10). The cathode lead of the diode should be connected to terminal (TS-10).
Ensure that a jumper is not installed between terminals (TS-8) and (TS-9).
Crank the engine.Result
The engine starts and the engine runs.The problem is in the switches for the oil pressure (OPS1) or in the water temperature contactor switch (WTS). Go to Step 5.
The engine does not start.The problem is not in the protection components. Check the time delay relay (TD). Refer to Testing and Adjusting, "Time Delay Relay Verification Test". Also, check the start/stop switch. The start/stop switch could have an open circuit to the terminal (TS-12) of the junction box. Check the wiring in the junction box in order to find the cause of the open circuit.
Check the protection switches.
Reconnect the jumper that was removed from the terminals (TS-9) and (TS-10) on the terminal strip in the junction box during Step 4.
Test the water temperature contactor switch (WTS) and the oil pressure switch (OPS1). Disconnect one switch at a time from the connection in the junction box.
Start the engine. If the engine starts, reconnect the switch and disconnect one of the remaining switches until the problem is identified.Result
The engine starts and the engine runs when the WTS or OPS1 is disconnected.One of the switches may be faulty. Refer to Testing and Adjusting, "Engine Oil Pressure Switch Test" and Testing and Adjusting, "Water Temperature Contactor Switch Test". Replace the faulty switch.
The protection switch is replaced and the engine starts.The problem has been solved. STOP.
The protection switch is replaced but the engine does not start.Check the switch that was replaced. Check the engine and the junction box wiring. Check the time delay relay (TD). Refer to Testing and Adjusting, "Time Delay Relay Verification Test". Repair the wiring and replace the components that are faulty. STOP.
The engine does not start when the WTS or OPS1 is disconnected.Terminal (TS-9) on the terminal strip of the junction box is being energized because of the wiring. Locate the wiring problem and correct the wiring problem. STOP.Problem 2
The engine does not crank.
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
