Troubleshooting and Repairing Your Yanmar Engine
Engine oil pressure indicator
Certain models of Yanmar engines are equipped with an engine oil pressure indicator.
This indicator can warn you of a critical engine problem before a catastrophic failure occurs. Typically, the engine oil pressure indicator displays when your engine oil is either too low or too high.
When the indicator displays, check your engine oil and add or remove oil as necessary.
Additionally, the engine oil pressure indicator can display if your engine oil filter is clogged and needs to be replaced.
If your Yanmar engine battery indicator displays, it generally indicates that your battery has failed.
Check the battery to ensure it’s in operable condition and that the connections are tight. If you are sure the engine battery is in working condition, you could have a faulty dynamo.

The engine starter motor operates, but the engine doesn’t start
When the starter motor operates, but the engine won’t turn over, it usually indicates that there is a problem with the engine’s fuel supply.
If you are experiencing this issue, make sure your engine has adequate fuel and that the correct diesel fuel has been used.
If your engine still won’t start, the fuel filter could be clogged.
Inspect the fuel filter, and if necessary, replace it. It’s possible that if the engine still won’t start, there’s a more advanced issue such as poor fuel injection, compressed air leakage or a faulty engine solenoid to blame.
The engine starter motor doesn’t operate or rotates slowly
Typically, if the engine starter motor isn’t cranking, there’s a problem with the electrical supply to the engine.
Ensure the battery is charged and the battery terminals are connected. If you’ve ruled out the battery, there could be an issue with a faulty starter switch or a faulty starter motor.
The engine is producing excessive white or black exhaust smoke
If your engine is producing an excessive amount of smoke, ensure you’re using the proper type of diesel fuel for the engine. If you’re sure your engine is receiving the proper type of fuel, then you can further determine the issue based on the color of the exhaust smoke.
White exhaust smoke can indicate a faulty spray pattern of fuel injection, fuel injection timing delay or that the engine is burning oil.
Black exhaust smoke can indicate the engine is overloaded, the air cleaner is clogged, a faulty spray pattern of fuel injection or an excessive intake or exhaust valve clearance.
