There we go then, thanks! Must be very thin, no wonder its fraught with problems. So I suppose if it looks like the copper wire is touching the main steel body, it probably isn't, because of the enamel.

On another note, Maz previously said the above, but if I do want to change to a Mosfet, which do I get, or are they all basically the same? There's some one ebay for example, for under £100...

The copper wire is coated in shellac, the burning out appears
to be due to overheating due to inadequate oil, hence extra oil spray hole.
oil cooling winding, basically i feel the stator is on occasions running max charge, I am unsure if it has a control module, I have no doubt we will find out!
early Norton ones were encapsulated due to vibration failure!
that does not look very tidy but functional, i have been involved in water pumps that require rewinds for many years

wire thickness and number of turns govern output followed by correct sequence, This would be done by hand big motor stators done on machine

That's pretty. Thanks for the pic, I had never actually seen this (very expensive) hole before...

It looks like even worse value for money when you see it from the other side.

£138 (It was £100, but then VAT and P&P)

Its all back together now. The hardest thing turned out to be threading the stator wires back up to under the seat. Thank god I left a red wire there when I yanked it out, but it was still pretty tough...

By the way, my battery is now getting a pretty healthy and steady 14.21V.
