I don't know about the numbers (don't have my manual handy), but the 
smaller-diameter wires going to the motor are the field connections.  The 
larger ones are the armature connections.

The symptoms you describe could be caused by an open connection in the 
field circuit.  This could be the reversing relay, dirty connections, or 
even an open field in the motor (unlikely).

They could also be caused by a mechanical problem such as locked brakes 
or a seriously munged transaxle.

I recommend obtaining the Homeowner's Service Manual from Bill Gunn.  It 
has excellent troubleshooting flowcharts.  You'll also need a multimeter 
(analog or digital).  You can get a suitable one for $40 or so at Radio 
Shack.
