Re: (ET) Snow thrower motor - working!

Well, thanks to all for the ideas on why my snowthrower motor pulled so 
many
amps. Just wanted to pass the right answer - thanks to Rhett George:

When I disassembled the motor I took care to mark (with a Sharpie) the
orientation of the brush holder. 'Course after I took it apart I thought, 
"I
should clean the housing while it's apart!" which, of course,  removed the
markings. I thought I still saw a mark and lined it up accordingly - after
all it could only go in two ways. Turns out the right way is the other way.
It spins like a champ now.

Ahhh - bring on the snow!
