Q:

I own a Craftsman 7500 Watt generator. The engine runs fine but I'm not getting any power to the outlets. Also the circuit breakers don't see to work. 580327181 Craftsman Craftsman 7500 watt ac g...

Q:

no voltage output on generac generator 7500 watt model 580.327181, purchased in 2000.

A:

The problem with the generator can be very frustrating. I did some research but was not able to find an answer to help with the generator. Your expert will be able to help give you a detailed answer. It may take 24-48 hours. I do hope that everything works out with the generator.

A:

I do believe, based on your findings, that the stator is indeed bad. Typically I would say to flash the field and make sure, but normally when the magnetism is lost there will be no voltage readings. It won't hurt to try flashing the field just to make sure.

To flash the field: Plug a regular corded drill into the 120V outlet. Set the drill to run in reverse and start the generator. Hold down the drill trigger and spin the chuck forward. Doing this will generate a minimal magnetic voltage that should get things back to normal if the rotor has lost its magnetism.

If that does nothing then I would say that the stator has indeed failed.

Q:

I have a Craftsman 120-240 volt 8000 watt generator model 580328391. It is only putting out 4.6 volts at the 120 volt outlet and 8.8 in the 220 volt outlet.

A:

The power module sends the dc voltage to the brushes to cause the alternator to generate the proper voltage. The residual magnetism in the rotor causes the alternator to put out the 4.6-8.8 volts. The power module converts the ac voltage to dc and sends it to the brushes, causing the alternator to put out 120-240 volts.

The power module is most likely the problem. The system control board (located in the control panel) could also cause this problem. It is unusual for the system control board to fail in this way.

I would replace the power module. I think that will solve the problem.

hello I'm Jamie I have a 7500 Watt craftsman generator. Model. 580327181 and I put it in shed like a dummy while I was using it and it got hot and quite putting out power to outlets. So I did same thing I took off the cover and everything looked fine except the rectifier pat 65795 was melted and I thought Mabye this was the problem cause everything ebiluututlse looked fine.but after reading what expert is telling u cause I checked outlet on the 110 and it put out 4.5 but the power regulator looked fine its not showing any signs of melting or damage so what do I do?
