Petrol Generator Problems

I have a small 2.2kva petrol genny which is running perfectly but isnt producing any voltage. I have flashed the fields using the old drill in reverse trick and the voltage starts up. I can use the genny for ages until I switch it off and attempt to start it again. It needs flashing everytime I use it. Anyone got any ideas what could be wrong? Capacitor perhaps?

Any help gratefully received!

From your link: If flashing the field does not make the generator work, you may have additional problems, besides a lack of magnetism in the rotor.

Looks like a lack of magnetism in the rotor to me!

Try running it on it's maximum load.

It could be that you are not really loading the field and a higher load would help. A fan heater is always a good load to try, or an electric kettle or both!

Ive tried running a 2kw heat gun for about 10 minutes. It did start up again fine but now im back to square one. I wonder if its the brushes? May have a look tonight.
