CHAPTER THREE
fo;*e running the engine. Install a test propeller to run the engine in a test tank. 2. Run the engine on a suitable test/flush device or in a test tank. Record the voltage at the engine speed specified in Tables 2-24 at the end of Chapter Seven. 3. Compare the output with the specification listed in Tables 2-24 at the end of Chapter Seven. Replace the ignition coil if the voltage reading is above the specification.Measure the exciter coil output voltage and measure the lighting coil output if it falls below the specification.CDI unit, pulses coil and lighting coil replacement are provided in Chapter Seven. 4. Remove the test harness and attach all leads to the proper locations.
WARNING SYSTEM Warning systems are used on 40-140 hp models to alert the operator to developing engine problen~s.Continued operation with the warning system activated can lead to serious and expensive engine damage. The systems vary by model and horsepower.
Warning Lamp Test A warning lamp is used on 40 and 50 hp EFGOIEFTO models to alert the operator that the engine is overheating or that the oil level is low. The warning lamp is mounted on the front surface of the lower engine cowling. 1. Turn the main key switch to the ON position. 2. Remove the electrical box cover. 3. Disconnect the bullet connector from the oil level sensor (Figure 17). 4. Connect the bullet connector (main switch side) to a clean engine ground and verify that the pilot lamp illuminates. Replace the lamp or wiring if the lamp fails to illuminate.
Warning Horn Test A warning horn is used on 40-140 hp models. On tiller handle models, the horn is mounted in the lower cowling of the engine. The remote control model has the warning horn mounted inside the control box. The horn sounds a constant tone to alert the operator of critical operating conditions such as a clogged or obstructed cooling water intake, overheating engine or low oil level. 1. Turn the main key switch to the ON position. 2. Remove the electrical box cover. 3. Disconnect the bullet connector from the oil level sensor (Figure 17).
4. Connect the bullet connector (main switch side) to an engine ground to make sure the warning horn sounds. Replace the horn or wiring if the horn fails to sound.
Oil Level Sensor Test An oil level sensor is used on all 140 hp engines and is mounted inside the remote oil tank. Each engine has an LCD display (Figure 18) mounted in the boat dash which monitors the engine speed, trim angle, engine temperature and oil level. 1. Disconnect the oil level sensor leads from the electrical box and remove the sensor from oil tank. 2. Reconnect the sensor leads. 3. Place the remote control lever in the forward or reverse gear position. 4. Turn the ignition switch to the ON position. Move the float on the oil level indicator into contact with the sensor switch. 5A. 115-140 hp-When the float (2, Figure 18) contacts the sensor switch (3), the lower oil level indicator (1) should flash and the warning horn should sound. When the float (5, Figure 18) contacts the sensor switch (6), the upper oil level indicator (4) should illuminate. 5B. 60-90 hp-When the float contacts the sensor switch, the warning horn should sound and the oil level indicator on the tachometer should illuminate.
