It is very easy to determine if a motor is series
or Sepex without opening anything or scouting for
obsolete information, simply measure the resistance
of the field winding.
If it is below 0.1 Ohm then it is guaranteed series
because it needs to be able to take full Armature current.
If it is in the order of 10 Ohms then it is guaranteed
a Sepex (shunt motor) because it needs to be able to
take the full pack voltage.

Peter,
My first EV (got it running 1993) was a Fiero, shown here in my driveway
after selling it to Jim Wierick,
http://www.evalbum.com/264
It doesn't run in the reverse direction like a Honda.
Please post pictures of the event.
I posted information earlier for a 5BT1346B50 series motor.
I'm not sure what the difference is with a B51
http://www.evalbum.com/tech/ge2.gif
The series motor will have S1 and S2 connections for the series field.
A Sepex motor would be labeled with F1 and F2.
Perhaps you could post a picture of the motor?
