Yes to both.
However, I suspect the bearing had failed years ago. As there was clickity, clickity noise that could be heard when the fan was operating at low speed.
The brushes were worn from normal use and to some extent from not running perpendicular to the commutator 100% of the time.
A long while ago a fellow Badwebber sent me his failed fan. But, it was oily inside, the brushes were worn from the oil?
here's a photo of the other fan

When my original '06 fan died I was 600 miles from home on a cool Pa. foggy morning, that later became a mid summer ninety degree day.
The fan literally went up in smoke. I thought the bike was on fire. The smoke boiled out of the gap between the front of the seat and the air box. I ripped the seat off as quickly as I could to find nothing but bad smelling electrical smoke. All that I could do at the time was to unhook the battery. Thankfully no fire!could a been a bad one!
The fan had been noisy for over a year, but the service manager at HD said it was "OK to run, they are all like that" . Yeah right. I cruised the 600 miles home making all of the keep it cool provisions that I could think of. It did fine. It never once hit run/skip even.
I believe what happened was that the commutator contact area looked like yours and it finally failed to start, rather than turn it just welded it's parts together.

When the fan failed (let the smoke out) was it still connected and controlled by the ECM?

Yes, it was all original under the ECM's management.
It had been noisy for about a year at that time, but the guru's at HD service would not replace it, telling me it was normal.
The replacement fan was on the bike for about a year before the skip spark started, and it took another year of fighting with one test after another for the skip/spark to get it to the manual fan switch.
The fan and cooling has been all good since the manual switching began.

Thanks for all of this information, it helped greatly.
I attempted this modification without having to grind the shroud and instead pressed the motor shaft out of the fan blade unit.
