So i bought a broken bosch professional gts10 on marketplace. It was a sparky boy. I measured the collector and it was cooked. So i orderen a new anchor, bearings and brushes.

But it still sparks very heavily as you see on the video

Im assuming the stator is done for aswell. But before throwing more money at this, is this the correct call? Or is there something im missing. I measured the stator with my multimeter but i couldnt find anything obvious.
