Hi,
Filp the switch on the front to trackiing and use a pair of these http://www.maplin.co.uk/p/p600j-6a-silicon-rectifier-uk61r to common up the output of the power supply, thus the heat gets dumped in both sides. The side away from the band goes to the red side of the power supplies, the side with the band gets commoned up and then connect to your motor. Connect both negative supply terminals together and to your motor.
One question what would happen if there was a severe overspeed of the motor?
now that's interesting. The unit was found with 3 leads - one red and two black. Just thought one red lead was missing. I wonder if this has been done before? As for running it too fast the tension of the belt on the flywheel means even at full power it will not throw the motion over excessively.
Thanks
