Parsun EFI Outboard Alarm Indicators: Diode/Lamp & Buzzer Functional Description (F15/F20)
Welcome to your guide to understanding the alarm indicator system on your Parsun F15/F20 EFI outboard motor.
These engines are equipped with a sophisticated warning system that uses lamps (diodes) and a buzzer to alert you to various operational statuses and potential issues.
Knowing what these signals mean is crucial for safe boating and timely maintenance.
Below, you'll find a detailed breakdown of the different alarm conditions and their corresponding indicator patterns.
| S.N. | L1 lamp | L2 lamp | Alarm condition |
|---|---|---|---|
| 1 | Off | 1 | Impulse coil failure. |
| 2 | Off | 2 | Intake pressure sensor failure. |
| 3 | Off | 3 | Voltage below 11V or over 16V. |
| 4 | Off | 4 | Throttle position sensor failure. |
| 5 | Off | 5 | Cylinder head temperature over 100℃. |
| 6 | Off | 6 | Intake temperature sensor failure |
| 7 | On | Off | Engine oil pressure. |
| 8 | Off | 9 | Fuel injector 1 failure. |
| 9 | Off | 10 | Fuel injector 2 failure. |
| 10 | Off | 11 | Ignition coil 1 failure. |
| 11 | Off | 12 | Ignition coil 2 failure. |
| 12 | Off | 13 | Fuel pump relay. |
- L1 lamp
- This refers to the first indicator lamp (diode) on starboard side or the lower of the 2 lamps.
It is typically associated with oil pressure warnings. - It is normal for the L1 light to come on and the remote control box to beep when the outboard motor is turned on before the engine starts.
- L2 lamp
- The number in the table indicates the flash frequency.
- This refers to the second indicator lamp (diode) on port side or the upper of the 2 lamps.
It is often used for indicating issues like abnormal power voltage or temperature sensor failures.
