Poor Generator Practice

Very informative thread! Thanks Tom!
PS: Why did it need polarizing every time it started? Was it lack of undercutting?

All the sparking from the brushes meant the armature was bad or the undercutting wasn't done right and allowing the brushes good contact with the bars. Luckily it was just the undercutting, and not a shorted armature. I've never seen a generator before that needed polarizing before each start, and this had me wondering until I saw all the sparking from the brushes.

Al, I'll come back with another picture and some more information.
