Petrol Generator Help

It could be just a bad connection in the blue socket. May be worth checking this first. A small 500 W /va gent will be more than enough for clippers, if you want to run small power tools like drills etc then go for something at least 1000w / 1kva.

Thanks, I'm going to ask a mechanic friend to look at it before I get a new one.

That sounds like an excellent plan - as flyingsparks has said, it could possibly be something very simple.

P.S. I bought a very nice little generator from either Aldi or Lidl (can't remember which - they're next to one another around here!) for an extremely reasonable price last year - and it's done quite a lot of work during that year!

Kind Regards, John

Thanks I'll keep checking Aldi

Your current unit is 2Kva so is around the 8.7A mark.

Are you coping with this output or is the unit struggling?

IE when you switch stuff on, does the engine start to struggle?

You may benefit from 3Kva, but of course it depends on your budget!

I only have one thing plugged in at once. It managed fine until recently.

You're trying to run a 45W tool on a 2kW unit. Have you previously had it working okay, but has now failed? Or has it never worked right? I'll suggest that the AVR may be struggling to regulate with such a small load. Try running a larger load, perhaps a 150W flood light and see if that is stable (pun fully intended)

I think these generators have two rotating fields and two output windings which can be connected in series or parallel to give 110 volt or 240 volt. From the volt drop I would assume one of the rotating fields is not connected could be as simple as a bad brush.

Looking at the Schematic Wiring Diagram I expect there is no AVR as such.

I worked with generators without AVR's on the Falklands and they had two resistors and two rectifiers one series and one parallel the parallel one small light was set up to give 220 volts no load and the other heavy one was set to give 220 full load but between no load and full load the volts would vary from 220 to 240 volts. This was good enough for lighting sets.

Yours seems to have a capacitor saw this system many years ago in Algeria never really worked out how it all worked but first step was to swap capacitor for known good one and that was often the fault.

The Schematic Wiring Diagram tells me very little but I would try capacitor first. Next is the rotating diodes.

 

[Maybedaisy]

It has previously worked fine. It just isn't kicking out enough power. The last entry is way too technical for me.

 

[securespark]

Eric is saying that one of the components called a capacitor on your generator may be faulty, causing the poor output voltage.

If you know anyone who is technical, it may save you a few quid to have it looked at before you ditch it for a new one.

Thanks I've got a friend who used to be a car mechanic I'll ask him to have a look.

Thinking of translation reminded me of this from my fave film:

If the genny is dead, a better option might be something along the lines of this:

Cheaper, quieter and easier

Hmmm. I rather doubt that 200W (about 0.83A at 240V) would suit the OP's requirements (1000W-2000W would probably be closer to the mark), even if it did, it probably wouldn't last for too long before needing recharging, even at 200W!

Also, do you know what the frequency and waveform of the inverter output is, given that you're recommending it to power motors?
