3. EXCESSIVE RESISTANCE BETWEEN THE GENERATOR CASE AND GROUND WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands NOTE: Make sure all test equipment and cables are clear of any belts, pulleys, or other moving parts. Start the engine and allow it to reach operating temperature. Is the voltage above 0.1 volts? Yes >> Repair the excessive resistance in the Generator Case Ground. Perform the PCM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING) No >> Go to 4 4. (K20) GEN FIELD CONTROL CIRCUIT SHORTED TO VOLTAGE Turn the ignition off. Disconnect the Generator harness connector. Disconnect the Powertrain Control Module (PCM) harness connector. Turn the ignition on. Measure the voltage of the (K20) Gen Field Control circuit. Is there any voltage present? Yes >> Repair the (K20) Gen Field Control circuit for a short to volt- age. Perform the PCM Verification Test Ver. 1 (Refer to 9 - No >> Go to 5 5. (K20) GEN FIELD CONTROL CIRCUIT SHORTED TO GROUND Turn the ignition off. Measure the resistance between ground and the (K20) Gen Field Con- Is the resistance below 100 ohms? Yes >> Repair the short to ground in the (K20) Gen Field Control circuit. Perform the PCM Verification Test Ver. 1 (Refer to 9 - No >> Go to 6 PM ENGINE ELECTRICAL DIAGNOSTICS - GPEC 9 - 883 |
