I have got 2.2kv generator... and voltage output on its volt meter shows as 210v instead of 220v... whereas all electrical appliances are working fine...
i just need to knw y its volt meter shows 210v instead of 210V ? and needle of volt meter is not stable it keeps moving slightly when generator is on. is this normal ?

Re: 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.
Do not play with it you are talking 240 volt.
I have been there & done that with a 2.2 kva genset.
what start as a small spring that broke, I thought I could just bend a new hook on the end of the spring & connect it again, the problem with that was by making the spring shorter it incrieced the engine revs & I burntout a power drill motor within a matter of seconds. I learnt a lot after speaking to the sparky who repaired the genset. you need to have all the proper gauges to adjust the current & volts. I can say it would seem the engine rev has a lot to do with the output.
Hey if you think theirs a problem take it to the sparky get him to test it, Don't do it yourself we could be talking life or death.

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
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
On the bottom right side of the engine there's a throttle with a set screw. This set screw is a fine adjustment for voltage control. The lever should be pushed until the set screw makes contact with the stop plate. Using a voltage meter, adjust the set screw until you hit 110 volt and then lock the set screw. I just bought the same generator, it was putting out 85 volts. Witha phillips screwdriver a wrench and a multi meter, I had 110 volts in less than 2 minutes. It now operates flawlessly.
Check the voltage with a meter in all the recepticles with your meter leads in the left and right slots on the plugs. Is that 184 volts AC there? If so, your gen has big problems with the voltage regulator. Let me know what you read. You can check the right slot of each plug to the round ground hole on the plug too, should be 120 volts there.
the instructions says the voltage regulator is automatic/digital. when you check the voltage is there any load on the generator? if applying load to the generator doesn't help, you can manually change the motor speed where the governor connects to the carborator, but it may change the frequency, but the regulator may fix it

OK, now to the problem. You say you have checked 67 volts is displayed on the generator output, I think this means that you see 67 volts on the control panel display when the generator is running. This can be several different problems: a) a bad CT/PT module that tells the controller the wrong voltage b) a bad A/D module inside the controller itself c) a bad voltage regulator
Get a real DMM meter and measure the voltages at the top side of the output (large) circuit breaker of the generator. Put the black lead of the meter on the neutral wire and then measure to each of the phase wires on the circuit breaker. If you get normal voltages then you probably have a bad A/D, if you get 67 volts on all 3 phases you have some other problem.
You still haven't told me what model/spec of generator this is, look on the data sticker on the generator cabinet.
