Generator overhaul

So as i mention in another thread my generator failed. The reason was that the coil insulation was damaged by the time (those things last only 50 years, cheap Italian cars) so coil itself came loose, start to vibrate and the cooper insulation damaged. In result the output wire inside the generator was cut and eventually red light came.
Because i am thinking to buy a 650 engine i didn't want to spend 40-60 euros right now for new coils and because i like to repair things i decided to repair it.
So i removed the coils cleaned them, paint again the damaged cooper insulation with enamel paint and put new insulation on the coils, a guy that repair motors gave me the special insulating materials.
Put everything back and generator came to life again. It is also working even better than before, now it needs less engine revs for the red light to come out and output voltage is normal.

Re: Generator overhaul

Nice job,
Most people would have just scrapped it. Todays throwaway culture is very wasteful. You were lucky to find a local supplier for materials. Many small outfits will help because you get to talk to someone who understands, not a receptionist. Trouble is small outfits are disappearing. Fortunatly the internet does have sellers of small quantities of specalist materials.

Re: Generator overhaul

That is some great work there, should last another 50 years
There is nothing to stop you retaining the Dynamo with the 650 engine. According to a knowledgeable mate of mine there was an economy version of the Polish 126 that was made quite late in the production run and had the Dynamo fitted.

Well i actually prefer the alternator configuration, so if my 650 come with it i will keep it, but i am not going to convert my 500cc with alternator, i don't think it is necessary.
As for the Gen. repair i think that for some guys repairing it is something that just don't exist!
I was really surprised speaking with a few car shops, they don't even carry a timing strobe light lamp, some newcomers they don't even know how to use it and i am talking about ''professionals''.
Unfortunately the good old days are gone for good so we must keep doing the dirty job i guess.
