Thanks very much for the information, but I don't have the Microscout in
front of me and won't be able to get my hands on it for a while. I'll
probably have RIS 2.0 before I get to my Microscout. When I do get it, I'll
give it a shot. Again, thanks for the info.

Last night I took apart my Microscout just to see what was going on...
Unfortunately, my pictures look like crap, so it'll be a few days before I
post those (at least, the closeups of the guts). In the meantime, you'll
have to suffer with my equally crappy ASCII pictures...
The thin metal strips are brushes.
Look at the side of the brush plate with the most metal showing. One set of
brushes (bottom brushes) should be vertical and at the bottom. The second
set (side brushes) should be horizontal and on the right-hand side of the
brushplate. The side of the brushplate without metal is the "motor side".
Their are two opposing clips on the brushplate. One clip is next to the
"side brushes". We'll call this the "right side", and the other,
appropriately, the "left side".
_________ # denotes metal. The perpendicular
lines are the brushes.
/### ###\
|### ... ###|
Left Side Clip ---> [|###| _|###|] <--- Right Side Clip
|###'.|.'###|
\###___###/
The motor's "bottom" has rectangular mounts that fit into the Microscout
casing. (They can be seen from the outside of a fully assembled Microscout,
if that helps). Here's ASCII of the relative key shapes:
o <-- Commontator Shaft
|_ _| <--- Motor Mounts
1) The little shaft sticking up out of the motor is a commontator. Set the
motor so this side is up.
2) Gently set the brushplate over the motor and clip the LEFT SIDE down
first. Very carefully move the brushes to fit around the commontator, but
DO NOT BEND THEM! (I used a precision screw driver). The brushes are
forked (like a snake tongue), so make sure both are adjusted.
3) Carefully clip the RIGHT SIDE into place. Do this little-by-little,
checking the brushes to make sure they aren't being improperly bent against
the commontator.
When I played around with mine last night, I only worried about the brush
tines that were closest to the motor body and then properly set the tines
closest to me after clipping the brushplate into place.
Proper placement of brushes will look somewhat like this:
___________
***
\ ***** The lines are brushes and the * make up the
com.
\***** Both brushes will bend slightly. They are
\*** purposely not tangent to the commontator.

Good luck! If this doesn't help, I can send you the current pics I have
(even though they are blurry/crappy).

Hmm... Well, you could try www.mindstorms.com (or whatever it is) and look
fo the
configuration. I remember looking around that side and seeing some diagrams
and shematics. I have that set too, and I have no intentions of taking it
apart (lucily)
