[TR] Wiper Motor Question

[G.D. Huggins]

All,

I have recently rebuilt the Lucas DR3A wiper motor from the TR4A.
I am attempting to bench test and just cannot seem to get it working.
I am drawing heavily on this (http://www.mgaguru.com/mgtech/electric/et217.htm) web site for information.

I am using a AC to DC converter, which puts out 15 v, as the power source on terminal 2.
I hook up the positive (+) to terminal 2, the negative  (-) to the "E" terminal.
This should create an attraction between the positively charged parts (terminals, field coil, armature, brushes, commutator) and the negatively charged housing.
When I add the third wire from terminal 1 to the "E", taking it to ground, nothing happens.

Any ideas?  I suspect I am shorting somewhere, or the power source isn't strong enough to make it run.




Cheers,
