Hi yeah, checked them. Then all look ok. All springs in place etc. I'm starting to tink it could be the windings. Might try to take it to an alternator specialist who refurb them and see what they got to say
Normally if the windings are suspect you will see evidence of arcing, though that isn't fool proof so you might be as well taking it to an electrical shop and getting them to test it as they know what they are looking for.
