Re: Fisher Price Motor Power

As a reminder, the FP motors have had a thermal protective device internal to the motor for the last year of two. It keeps the motor from smoking but it lets go when you need it the most if you haven't done your calculations correctly. Please be aware that covering the holes in the frame is a good way to find out how the thermal device works. It is in series with one of the brushes and you can see it using a bright light if you look.
