Took apart and cleaned up the power feed that came with my 8520. Prior to disassembly, the unit worked ok but seemed to be scroll faster in one direction compared to the other, so I wanted to investigate.
Problem seems to be in the potentiometer which is huge! Maybe thats not what its called for this application, or it's something else entirely, but that's what I'm calling it lol. I'll add a short video so the experts here might be able to tell me if its no good, or fixable. Under the wiper arm you can see a small retaining clip or something, It seems like theres not much down pressure on the wiper and maybe that clip is supposed to be positioned to help with the downforce on the wiper?? I dunno, just seems like an excessive amount of sparking to be working correctly.
While motoring, it has a faint burning smell also. Took the endcap off the motor, and could see some darkness on the windings. Thinking this thing got hot at some point. If both the motor and the pot need repair or replacing, is there any hope or is this better sold for parts??
