So today i i switched on my BB in moc, which hasn't moved about a year. Then the problem occured: 1 xl motor worked fine, but the other not. So i took motor out and tested it. Motor run's fine in one direction, but if you switch it to other direction, it wobbles for 1-2 seconds and then stops, beacuse BB switch itself automaticly off. I opened the motor, but i can't see ant problems. Do you have any ideas?
