My generator (MQ Power Whisperwatt generator model DCA-45SSIUII)was running during a power outage and it shut off and will not start back up. The oil and water were fine. It was about 20 degrees outside at the time. It did not run out of fuel. It usually starts with just one turn of the motor. I did spray ether in her and she did crank up for a second. Thanks for any advice. Wayne

No wiring diagram available from Briggs. Try re-magnetizing the rotor. No AVR or Capacitor listed in the parts list.
Disconnect the wires to brushes ( pay attention to the order) and apply 12vdc to brushes. Positive goes to brush closest to the bearing. Start the generator and check for output. If output is normal run the unit a few minutes to ensure re-magnetization then shut down normally. After shut down disconnect the 12 vdc source and re-install the previous disconnected wires. Now re start the generator and test for output should be okay provide there is no problems with the alternator. If no output during the above re-magnetization then your rotor windings my burned out.
I recently had a similar problem during "Sandy". I forgot to turn off the hot tub before starting the generator and the house lightswhere barely lit, dim, and flickering under the load. I quickly shut itoff andthe hot tub, but not before frying half of my generator. It will only produce 110now, not the 220 usual adn I need to get it fixed. I imaging you may be experienceing the same thing if you can't reset it. My generator has two reset buttons right next to the outlets on the unit itself.
Overcrank means that it tried to start and couldn't. It will go through 5 crank cycles and then stop with this alarm. Switch to off, hit enter to clear fault and then try to start in manual. Check to make sure you have fuel and pressure is 11 to 14 in WC.
its possible the overspeed is set to sensitive.
or your rpm are to high.
these are preset in the factory as a safety, check your manual to ensure your rpm speed is in
the pre set area.
generators will do this under load when you have a big load on them or take a load off.
the governor will some times over compensate causing it to trip on overspeed.
Although packing it in dry ice could be an option I would recommend checking the thermostat and the coolant pump. Check to see if the hoses have pressure in them by gently squeezing them just as the engine is warming up. 100-105 degrees. Be careful after that. If you don't have callouses ;)
