I am kind of noob with these motors. When I got it, it was hard to determine where I should solder the power wires from the speedo. I am a decent solderer but it was still extremely hard to near impossible to make this sucker work. I cleaned everything sanded down a spot on the brush tube and did my best, but today I was fooling around with the brushes and I noticed that it was soldered right on the brush wire...I give the motor wire a little tug and the brush wire snapped in half.....there must be an easier way to do this! Any tips on soldering with these motors. I don't need any basic soldering tips...but what I need to know is where and how did you solder your power wires on to this motor...thanks!
