Hurm, that is interesting. I figured the 0.1 ohm was way too low, but if
that is in the generally correct range there is a possibility that it
was just a bad fuse....but I really don't want to test by blowing
another fuse if there is a cheaper alternative ;>
How many amps do you think I should fuse a 12 volt battery at to try and
spin the motor in neutral?
(I have a 3 amp 30 volt bench power supply...would 90 watts be enough to
make it turn at all in neutral?)
I haven't looked at the brushes yet, I'll probably want to tow it home
first (it's only about 1/2 mile away as this happened about 1 minute
after I left).

I'm pretty sure terminal resistance is supposed to be 0.03 ohms so a
normal ohmmeter won't tell you much... How about spin the motor in
neutral with a (fused) 12V battery? Any signs of arcing on the
commutator?

Today my HV fuse blew, and after testing my controller, I believe
the problem is that my 9" FB1-4001A DC motor is shorted. The
motor leads are measuring at 0.1 ohm right now.
Anybody have suggestions as to anything to look at/for before I
start the process of removing the motor?
I may also be in the market for a new/used FB1-4001A depending upon
how things go....
