CDI Electronics Outboard Ignition Troubleshooting Guide

128 TROUBLESHOOTING GUIDE - Tohatsu/Nissan Troubleshooting Tohatsu/Nissan Troubleshooting 4. For models 40, 50, 70 and 90A, check the Stator as follows: WIRE READ TO RESISTANCE White/Red White/Blue 438-592 Ohms Green White/Yellow 61-82.6 Ohms 5. Check the ignition coil resistance as given below: WIRE READ TO RESISTANCE Black/White Engine GND 0.9-1.2 Spark plug wire Engine GND 12.25-12.75K TIMING FLUCTUATES: Service Notes: It is normal for timing to fluctuate 1 to 2° @ idle. 1. Clean and inspect all ground connections. 2. Check the Crank Position Sensor air gap. Should be 0.020-0.036 inches or 0.5 mm -0.9 mm. 3. Check the Crank Position Sensor resistance as given below: WIRE READ TO RESISTANCE Green/Red Blue/Black 451-611 4. Check the Throttle Position Sensor and the Engine Temperature Sensor. 5. Check the ECU. TIMING WILL NOT ADVANCE: 1. Check the Crank Position Sensor and the Throttle Position Sensor. 2. Check the ECU. ENGINE MISSES AT HIGH RPM: 1. Check for correct spark plugs (See data sticker on engine). 2. Check the Crank Position Sensor. 3. Check the battery voltage. 4. Check the ECU. 5. For models 40, 50, 70 and 90A, check the Stator as follows: WIRE READ TO RESISTANCE White/Red White/Blue 438-592 Ohms Green White/Yellow 61-82.6 Ohms ENGINE HARD TO START WHEN COLD: 1. Check the Engine Temperature Sensor and the battery voltage while cranking (battery voltage should remain over 10 volts). Remember, a 1000 CCA battery is recommended for the direct injected engines. 2. Check and clean the battery cable connections, both on the engine and the battery. 3. Check the Harness for loose connections between ECU and Starter Solenoid. ENGINE MISSES @ LOW RPM, BUT RUNS SMOOTH @ HIGH RPM: 1. Check the Harness for loose connections between ECU and Ignition Modules. 2. Test the battery and battery connections. Try another battery and see if the problem goes away. ENGINE STARTS HARD WHEN HOT: 1. Check the Enrichment Solenoid (Carbureted engines). 2. Check the Engine Temperature Sensor and the Crank Position Sensor. ENGINE WILL NOT RUN OVER 3000 RPM AND IS NOT OVERHEATING: 1. Check the Engine Temperature Sensor and the Throttle Position Sensor. 2. Check the ECU, Map Sensor and Shift Interrupt Switch. 3. For models 40, 50, 70 and 90A, check the Stator as follows: WIRE READ TO RESISTANCE White/Red White/Blue 438-592 Ohms Green White/Yellow 61-82.6 Ohms
