If your MQ Power Portable Generator engine starts and the engine speed switch is in HIGH position, but the engine speed rises and remains at high speed when the engine speed switch is placed in the LOW position, the problem might be a defective engine speed switch or a defective solenoid. Replace the engine speed switch and/or the solenoid.
Why MQ Power WHISPERWATT engine vibrates excessively?
If your MQ Power Portable Generator engine starts and the engine speed switch is in HIGH position, but the engine vibrates excessively, it could be due to a bad engine installation. Reinstall the engine.
How to fix MQ Power WHISPERWATT Portable Generator when engine fails to start and starter does not rotate?
If your MQ Power Portable Generator's engine won't start and the starter doesn't rotate, the possible causes include a dead battery, a defective starter switch, a defective starter, or a burned-out fuse F5. You should replace the battery, the starter switch, the starter, or the fuse, depending on which one is the cause.
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 seems overloaded?
If your MQ Power Portable Generator engine starts and the engine speed switch is in HIGH position, but the engine seems overloaded, the issue might be a defective alternator or damaged alternator bearings. Repair or replace the alternator, and replace the alternator bearings.
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.
Why MQ Power WHISPERWATT Portable Generator engine fires then stops?
If your MQ Power Portable Generator engine fires but stops as soon as the starter is switched off, the issue might be a blocked fuel filter, a blocked fuel supply, or a defective fuel pump. Replace the fuel filter, check the entire fuel system, and replace the fuel pump.
What to do if MQ Power Portable Generator will not start?
If your MQ Power Portable Generator engine will not start or the start is delayed, even though the engine can be turned over, it could be due to several reasons. There might be no fuel reaching the injection pump, a defective fuel pump, a clogged fuel filter, a faulty fuel supply line, compression that is too low, the fuel pump not working correctly, low oil pressure, exceeding the low starting temperature limit, a defective battery, or air/water mixed in the fuel system. Add fuel and check the fuel system, replace the fuel pump, replace the fuel filter and clean the tank, replace or repair the fuel line, check the piston/cylinder/valves, check the engine oil pressure, comply with cold starting instructions, charge or replace the battery, and check for loosened fuel line couplings.
What causes MQ Power WHISPERWATT engine to stop by itself?
If your MQ Power Portable Generator engine stops by itself during normal operation, possible causes include an empty fuel tank, a blocked fuel filter, a defective fuel pump, or the mechanical oil pressure shutdown sensor stopping the engine due to low oil. Add fuel, replace the fuel filter, replace the fuel pump, add oil, and replace the low oil shutdown sensor if necessary.
Why MQ Power Portable Generator engine overheats?
If your MQ Power Portable Generator engine overheats, it could be due to too much oil in the engine crankcase, a contaminated or blocked cooling air system, a broken or elongated fan belt, insufficient coolant, a radiator clogged with dust, a defective fan, radiator, or radiator cap, a defective thermostat, or a defective head gasket with water leakage. Drain off excess engine oil, clean the cooling air system, change or adjust the fan belt, replenish coolant, clean the radiator, replace defective parts, check and replace the thermostat if necessary, and replace any defective head gasket parts.
