SOURCE: North Star 5500/ lost one leg of the 220v

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: generator 4 prong220v outlet to 3 prong 220v plug

Go to your electricians store and ask if they have a converter plug, Don't go to a Homedepot type place, go to the specialty place where electricians go. Their depth of knowledge is way better.

How to test the electrical system of the generator for free


Ez test to determine if stator wiring is ok. This test works on generators that have two sets of 115v plugs and 220v plug. Use a 12v, 1amp ac power supply ( smaller ac power supply should work ok ). With generator not running, apply 12v to one of the 115v outlet plugs. Now verify 12v output voltage with meter at another 115v outlet on generator. Also verify that there is about twice the voltage at the 220 v outlet plug (should be about 20v - 24v) . If the adjoining 115 v outlet plug has no output or very little voltage or if the 220 volt plug has no output, most likely stator is damaged or breaker is off. If the stator is shorted voltage reading will be very low and power supply will heat up. If stator is open, there will be no voltage at second 115v plug or 220 v plug. If voltage is ok at the other outlet plugs as per test above then most likely problem is with voltage regulator, or brushes not making contact or armature winding open or just needs to be energized. Unplug the 12v power supply after test to prevent it from overheating. Most generators have two 115v windings that together power the 220v plug. When you energize one of the windings with the 12v power supply, the second 115v winding will be energized also and give you a voltage reading about equal to 12v. You will not damage the generator with this small voltage being input thru the plug. Good luck

Briggs & Stratton Briggs Stratton 6200 Watt Portable Generator voltage adjust


Usually the cause of slightly low voltage like this is that the engine is not running at full operating RPM. Find the high speed adjusting screw on the govenor linkage and adjust the engine RPM until the output is 220V - 240V

You will have more available power (and use a different larger breaker already on your generator) if you use the 220 plug instead of the 115v plugs. Have an electrician make you an breakout box separating the 220v plug into two 115v outlets. Or your can replace the push button breakers with better quality 25 amp. Problem is that the 115v receptacles are probably 15 amp. Other solution is to try a 220v pump instead of 115v (more efficient draws less amps). Good luck

The genset power most likely is 220V line to ground power. You utility power is 220V line to line but uses 2ea 110 VAC line inputs to get that 220VAC. The only way to correct this is to reconfigure your generator connection to 220V line to line IF possible. Some generators that only have a 220V output. Re-configuration is not possible

Measure power at the breaker on gen power as the source and again with the utility as the source. You will see the difference in voltages. Utility power.... each side of the Breaker output to ground = 110V across the 2 terminals 220V

Gen power one side of the breaker output = 220V other side = ZERO.

You can make it work but it would take some heavy duty relays in a power sub paenl so that when the generator is running one side of the power is 220V and the other side is Ground. Once utility power is restored the relays would disengage and power would again be 220 VAC line to line.

You will need a licensed electrician and a PERMIT to install a relay panel such as I mentioned above. Improper wiring of the power relay swtitching panel can cause major power problems in any given installation and trip the MAIN PWR breaker.

Thanks for choosing FixYa.

How to adjust voltage output from generator ?


As long as your appliances are working properly I wouldn't worry. A 10V drop from the norm is not that crazy and certainly not abnormal. If it drops down to 205 or 200 then I would worry. I'm not familiar with the internal components of a home generator but I would imagine they are not as precise as the machines the power companies use. And when you look at it from a phase point of view its even less of an issue. There are 110-120V per single phase and 220-240V double phase. So on each phase your only dropping 5V out of that range. And as far as the needle jumping, again not very precise, and it will probably move even more while its generating. If the voltage does happen to drop more check for a loose neutral wire, that will often cause crazy voltages, but so far I see nothing to worry about.

Older Coleman 3500 Watt generator, sitting for over 2 years. engine starts and runs normally, but no power generated.


there can be many reasons. need more info:
Is it Inverter typr generator?

measure output voltage - anything?
take back cover off generator itself, measure continuity of stator and rotor, and visually inspect windings. You'll find AVR module there too, it may be the reason.
