i think the resistor thing is different in the 2001, my memory is foggy, and the solder thing was not applicable. those instructions were for the 99's. and the same is true for the 2000 shop manual, it still shows the 3 or 4 speed switch. ours, (2001) has a "variable" speed switch.
you can do this repair yourself if its the resistor, which it sounds like it is. i just replaced mine a couple of months ago with one from a wreck. call merlin for new, or some of these parting out threads, and get you a resistor from another 2001.
the instructions on acessing the resistor is the same as the 99 instructions, pull the old one out, and plug the new one in.
start to finish, less than 10 minutes.
