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,
Guy D. Huggins
