This is bad... ...will you please post a picture of you motor -- especially the sticker on the side, a close up of the gear would be good too.
If you have 15T, then F-P has provided and/or FIRST shipped a mixed lot. Without actually taking the motor of the transmission it is close to impossible to tell the difference. Even off the transmission it can be very hard to make the ID.
Paul Copioli and I can tell you that the folks that service these transmissions for F-P (in the Detroit area in is McNichols Electric just down the block for Beaumont Hospital on 13 Mile) have absolutely no idea which motor is which, in fact, the guy told me he goes SOLELY by the # of teeth on the motor pinion when he sells a motor. Paul and I both told him that this is not really an adequate method, but I don't think we made a dent.
If I were you, I would a stall the motor (for a short period of time) at 0.8 volts or so and accurately measure the voltage accross the motor and the current. If the current is not about 10 Amps at 0.8V (i.e. the Resistance should be 0.08 Ohms per the spec) ,you have confirmation that you have a different motor than the rest of us.
How many other teams have counted the pinion teeth carefully? Any more 15's out there?
