electrics-what have I done?

[ronmidg]

The generator light has been flickering recently and now is on all the time. Its a suitcase motor so carbs and covers off to get at the alternator. Removing the right carb revealed a not connected black wire which I labelled as off the rectifier when I had the engine out about 400miles ago. Oddly the rebuild was charging ok for about 300 miles.
Reconnecting and rebuilding still have the generator light on.
So the question is what have I cooked, the rectifier or the alternator, or both?

sounds like brushes worn out to remove in situ ,take off (as looking at engine from lid)right hand cover tin ware,then working over exhaust from under side remove bracket slide adjuster.take out long bolt and alternator should slide out.at lest from memory its a while since i did one.no need to remove carb etc.mind you its a sod with the engine out :!:
