So, I checked the brushes, they look good.
I looked at the controller, and quickly figured out I am not versed in messing with it!
How in the world do you bypass this thing? I can see the black and white wires coming out, probably need to be connected. But it also has a red wire by itself, coming from the power switch. And a bundle with red, black and white coming out and going to the variable speed dial on the handle.
Would I cut and cap the single red wire. And unplug the 3 wires going to the speed dial. Then connect the black and white larger gage wires together?
I will get a variable external controller later, if I can achieve this step!
Thanks for any help guys!
