Yesterday I plugged in my wheel, flipped the foot pedal switch to on, and depressed the pedal. I got a flicker of sound and maybe some rotation of the wheel but only briefly. Checked wall plug, extension cord, etc everything fine. The power cord was old and looked awful so I decided to replace that before I did any troubleshooting. Cord replaced, still doesn't work. So I try hard-wiring through each of two fuses to see if the light goes on. Sure enough, one of the fuses is shot (ceramic fuse, 10a@250v) so I decide that I will put a little bit of copper wire in there that I am guestimating will burn out at a capacity somewhere near but below it's rating and use it for the time being at lower speeds, drawing less power through the temp fuse. But it pops the copper wire instantly, so I go up in "guage" and it pops that too. It looks like for some reason the fuse is being made to bear tremendous loads of electricity when it shouldn't and I have no idea why this is occurring. Does anyone have any thoughts on what the trouble might be? Everything inside the foot petal box (this is entirely where all the electronics are, as opposed to, say, a Brent) looks very clean and there's no indication of a simple short caused by something bent, broken, or worn out.
Don't have a dime to my name and won't get a new one for a really long time if I don't fix this myself.
