Small generators like this almost always have 2 stator windings 180 degrees out pf phase, that's how it makes the 220.
At the back (maybe side) of the outlet box should be a molex type plug that has the wires from the stator, get an ohm meter and measure them (with the generator shut off of course). You should find that you've got 4 wires in the plug, 1 wire for each end of 2 coils. From one end to the other of each coil you should measure less than an ohm, between the coils there is usually no connection, but some models have the neutral ends of each coil connected together inside the generator housing.

It sounds to me like you've got one of the power windings open...

SOURCE: I have a North Star generator running on gasoline.

how old is the gas in your machine?? there are several things that could cause this ..how severe are the fluctuations in rpms does it go way up and way down or is it slight ?have you tried a carb rebuild? if not dont untill we try a couple simple procedures first
if it is within your expertise to follow a few simple steps i believe we can get the problem solved.first if there is any old gas in the machine dump it and clean tank also if it has a inline filter for gas replace it.if this dont cure it remove the plug and replace it with a new one or clean it good and put it back in if this dont take care of it email me at [email protected]
i will walk you through a few more procedures i am more than confident we can do this and save you a great deal of money no cost to you .i hope these do fix you up but if not contact me i can even call you and talk you through some things i have no cost long distance if in us or canada keep me posted DALE

SOURCE: I have a honda generator em2500x voltage problem

Cummins P2200, 2KWatt, it starts fine, but after a couple of minutes, it gives quite high voltage output, meter needle goes beyond 300v, engine speed seems high since throttle is increased, indicator light on generator also becomes bright, after a minute or so, things come to normal, sometimes takes few minutes to come to normal, situation is same, with/without output load. this happens within initial 15 minutes after startup, afterward everything is normal.

SOURCE: how to flash field north star 5500 generator

wire a 120v 15a to 9vdc or 12vdc battery make sure you have no voltage out of the 240 side. with the unit running plug into the 120v receptacl QUICKLY pull out. check power out put. if it did'nt work check your battery, than do it again twice as long. you must check all component before doing this to make sure you don't have any other fail-er. this is danger-us be careful. good luck

North star 5500 generator works fine but on voltage output


It's very common for the connectors between the alternator and power outlets to come loose on these. Give them a check and tighten as necessary.

Adustments engine speed low rpm


You cannot adjust the voltage output. All generators are rated for 110-125 volt recepticals and usually have at least one 220-240 volt receptical for special appliances that require it such as water heaters, pumps, welders, air conditioners. When one of these higher draw appliances is connected and they begin to draw amperage, the gas engine will automatically increase rpm to produce enough amps. If your generator gauge is showing low voltage such as 60,80 or 90volts for example, then you have overloaded the generator and blown a capacitor, resistor or similar item.

I have a Suzuki gasoline generator Type SE 3000 A . It runs but give no power. No 12V or 220 V. Help


most likely it is the AVR, they tend to get zapped when you turn the generator off with a load on.. or run out of gas with a load on..
Always turn off or disconnect your load before shutting down.
other possible problem is the brushes might be worn down.. but that is rare...i'd check the AVR 1st .
the AVR is a regulator. and is located under the generator cover.
it is a block looking item. 2 connectors, 2 wires goto the brushes, and the other is a molded nylon connector.
there are 2 different models, type A and type B.
they do sell them on ebay for less than $90.00
once you install it,, start the generator up to confirm power out out with a accurate meter.. the voltage should be close, there is a small tiny brass adjustment ***** to fine tune the voltage..
after that reassemble..
( NOTE, the new AVR might not be the same size as the original, so you may have to fabricate you an adapter plate.. make sure you secure it well either way you go.
good luck..

I have a Coleman Vantage 3500 motor runs no generator output


This sound like a loss of residual magnetism in the generator. The field will need to be "flashed".This is also known as re-exciting the field of the generator.
The Coleman manual gives these steps:
1Use a 6 Volt lantern batters (dry cell) or a 12 Volt automotive battery.
2.Disconnect all loads from generator.
3. Remove the brush cover (that's the rectangular plastic cover on the end of the generator.)
4. Plug a lamp or light into the generator before starting the engine. The light will illuminlate when ?Voltage has returned.
5. Start the engine with no load connected to the generator.
6. Attach the "-" lead of the battery to the negative brush. Very briefly touch the "+" lead of the battery to the positive brush. Remove as soon as Voltage builds up.

I have a honda generator em2500x voltage problem


My E2500 did this. Turned out to be dirt in the brush holders causing the
brushes to have less pressure in the slip rings. Stopping and restarting
joggled the brushes to make better contact until they wore down again.
Pull your brushes and make sure they slide easily in your holders. Also
you may need to replace them if they are worn too much or clean the
slip rings. Good luck. Doing your own repairs is fun.... especially when
they work.

Engine runs but no power aat outlet????


Start with brushes and rings. Make sure your rings are clean and the your brushes have a good length. Flash the fields with 12V battery. Apply positive to the brush nearest the bearing and negative to the back brush, while genset is running. Use rubber gloves when doing this and keep hands away from rotating parts. You should see the voltage climb when you flash the fields. This would mean that you need a voltage regulator. If voltage does not climb, then you will need a new genset.

Generac portable generator doesn't produce power


Remove front cover on the genset and you will see the brushes and rings. Clean the rings if black with emory cloth and inspect brushes. Flash the fields by apply a 12V battery to the brushes. the brush closest to you or the bearing is connected to the positive side of battery and the back brush is negative. You have to do this with genset running. You should notice your voltage climb up to over 50Vac maybe even over 100Vac. Make sure to use rubber gloves when flashing fields and keep hands away from rotating parts. if voltage does increase when flashing the the voltage regulator is shot. If voltage does not climb then you will need a new genset or generator end.

Powermate PM0496500.02 No voltage output


Here is a simple test to check field and other wiring. With engine off apply 12v ac 1 amp to 110v outlet plug on generator. This will energize the field windings and should cause the armature to produce dc voltage at the brushes and produce a nice magnet. If there is a short in the field or broken wire or shorted capacitor there will be no dc reading at the brushes. . This test is the opposite of what actually occurs when the engine is running. That is the armature produces a magnet fed thru the windings, regulator and brushes. If dc voltage is present at the burshes, remove 12v ac and start engine to check for output. enjoy
