The brushes need to be filed smooth or replaced. 15 minute job, remove 2 bolts on the generator cover ( side opposite the pull start ). Remove 2 more bolts holding a black plastic thing about 4 inches long on the left. Behing that piece, there is 1 bolt holding in the brushes ( red and white wire attached ). Remove the brushes and if they're not smooth, file down and reconnect everything. I was done in 15 minutes in the middle of Maine woods thanks to my Leatherman.

Wen 5500 got from guy had for backup to home. He had 8 years only ran @ 8 hrs started regularly. It will run smooth with like battery chargers,with saw backfires and stalls. Carb clean n valves good.

the low oil level control unit can malfunction causing problems similar to this . Test by bypassing the unit
have it checked out
next-- in the tap that is screwed into the tank there is a very fine filter that may be blocked
taps are made of diecast metal and over a period of time will corrode internally and restrict fuel flow
just some points to check out

5500 watt generator will not run my 2hp air compressor

5500 watt generator will meet the 1491.4 watt requirement of the 2 hp compressor motor
given that 5500 watts generator is rated continuously at around 4500 watts and will handle spikes to the 5500 watts when electrical components start there should be plenty left
consider the possibility or a motor below full capacity, carby problem ( jets blocked , water, blocked air filter not getting full throttle from the governor lever, worn rings, type of fuel in use --E mix)

I have a Wen Power Pro 9000, 16 HP Generator. Couldn't run my coffee maker this morning. Used a multimeter and was only getting 35 volts. Is it brushes or something more complicated. Rob

When was the last time this generator was run,allot of times they lose their magnetism from sitting so long? Also you may want to check your voltage regulator to make sure it is putting out the correct voltage..

5500 generator stopped producing eletric after

First check with the dealer and see if it is still under warranty. If it is not, make sure nothing is blocking the air flow around where the control modules are located. This could cause the voltage regulator and other electronic parts to overheat. Next check the brushes and make sure they are free of any dust or build up preventing them from making contact.

If everything is OK the next thing I would do is change the voltage regulator.

I've got a Power Pro By Wen Power Model 9000 16 HP Generator - kicks on with one pull however shuts down after about 10 min of operation. I've changed the oil and cleaned the air filter. Any other...

Check the gas cap. There is a vent to allow air into the fuel tank as the fuel is drawn out. If this vent becomes clogged, a vacuum can be formed in the tank. This can prevent gas from flowing to the carburetor.

Listen carefully when you remove the cap. If you hear a "whoosh," there likely was a vacuum.
