The set point for high coolant temperature on the MQ Power Portable Generator is 212°F (100°C).
What to do if MQ Power WHISPERWATT is low on fuel?
If your MQ Power Portable Generator is low on fuel, add fuel to the generator.
What to do if MQ Power WHISPERWATT engine has no voltage at AC power source?
If your MQ Power Portable Generator engine starts and the engine speed switch is in the HIGH position, but no voltage is present at the AC power source, it could be due to several reasons. The rectifier, rotor, or voltmeter might be defective, or there could be disconnected wiring, a layer short circuit in the armature winding, or a defective AVR. Consider replacing the rectifier, rotor, voltmeter, or armature. Check and repair any disconnected wiring. Replace the AVR if necessary.
Why MQ Power WHISPERWATT has low engine power, output and speed?
If your MQ Power Portable Generator experiences low engine power, output, and speed, it could be due to an empty fuel tank, a clogged fuel filter, inadequate fuel tank venting, leaks at pipe unions, an engine oil level that is too full, or injection pump wear. Add fuel, replace the fuel filter, ensure the tank is adequately vented, check and tighten pipe unions, correct the engine oil level, and use only No. 2-D diesel fuel.
What to do if MQ Power WHISPERWATT Portable Generator voltage is too low?
If your MQ Power Portable Generator engine starts and the engine speed switch is in the HIGH position, but the voltage is too low or cannot be used, the issue may be a defective circuit breaker, a layer short circuit or broken wires in the armature winding, or a defective AVR. Replace the circuit breaker, repair or replace the armature, and replace the AVR if necessary.
What to do if the circuit breaker tripped on my MQ Power Portable Generator?
If the circuit breaker tripped, it could be due to several reasons. First, check the load for a short circuit and repair it if necessary. Second, the generator might be experiencing overcurrent; confirm the load requirement and reduce it. Third, the circuit breaker itself might be defective, so check and replace it if needed. Finally, the overcurrent relay may have been activated; in this case, confirm the load requirement and replace the relay.
Why MQ Power Portable Generator has black exhaust smoke?
If your MQ Power Portable Generator experiences low engine power output and low speed, accompanied by black exhaust smoke, it could be caused by a blocked air filter or incorrect valve clearances. Clean or replace the air filter and adjust the valves per engine specification.
What to do if MQ Power WHISPERWATT Portable Generator shows SupplyingLoad Alarm Not InAuto?
If your MQ Power Portable Generator displays a 'SupplyingLoad Alarm Not InAuto' message, here are some steps to take: 1. Check the digital controller screen for any Diagnostic Trouble Codes (DTCs). 2. Press the OFF button on the digital controller. 3. Place the Control Power switch in the OFF position. 4. Place all circuit breakers in the OFF position. 5. Allow the unit to cool down, then inspect and repair any problems before restarting. 6. Before restarting, ensure the Control Power switch and all circuit breakers are in the OFF position. 7. Restart the generator, ensuring all fault messages are cleared from the digital controller display.
Why MQ Power WHISPERWATT battery discharges too soon?
If your MQ Power Portable Generator engine starts and the engine speed switch is in HIGH position, but the battery discharges too soon, the issue might be a defective engine regulator or defective wiring. Replace the regulator, and repair or replace the wiring.
Why MQ Power WHISPERWATT engine remains at low speed?
If your MQ Power Portable Generator engine starts and the engine speed switch is in HIGH, but the engine remains at low speed, the problem could be a defective engine speed switch, a clogged fuel strainer, a clogged air cleaner, disconnected wiring, a defective solenoid, or a burned-out fuse F2. Replace the switch, clean or replace the fuel strainer and air cleaner, check and repair the wiring, replace the solenoid, and check the solenoid circuit and replace the fuse.
