Re: (ET) Motor Swap & kill a watt

[David C Robie <mycroftxx1 juno com>]

If motor  has to run in reverse, remember that the brushes may be factory
 set for forward operation, not neutral position. This, of course, means
inefficient operation. It would pay to check this - but wait for another
answer on this board someone may know  whether 20 motor brushes are
factory set advanced for fwd direction or not. Any sharp electomechtech
or even some degree engineers (most of em seem to get 'dilberted' a lot)
would advance em to begin with.
