Variable Speed Wiper Motor Woes (1964 Valiant)

I have the variable speed wiper setup in my 1964 Valiant. I tried wiring it up last night and it immediately popped two ten amp fuses back to back in my new wiring harness (Ron Francis). I put a 30 amp fuse in just to see what would happen. It didn't blow. The wipers made a brief noise and stopped. If I pushed on the wiper motor, I could hear the motor whine like it was trying to move, but it didn't do anything. The wiper motor and switch are original to the car and worked when I took it off the road. Here's the only thing I've done with them since I took it off the road to restore it five years ago:

Both switch and motor were sprayed with electronics cleaner.
I added a ground wire to the outside lip of the switch casing by securing a ring terminal to it with a hose clamp and running it to a grounding bus I have under the dash.
I ran a wire from the grounding bolt of the motor and ran it to the same grounding bus.

Here's what I was experiencing with my test light:
Power was going into the switch. (Pink wire)
Power was coming out of the switch through the red wire running to Field 1.
No power through the yellow wire going to field two. (I assume that's because Field 2 is for the return motion.)
Power through the wire connected to the "armature" connection when the switch was on.
Power going to the "park" wire when the switch was off.

So it would seem the switch is working ok. I think it may be the motor that's acting up. Any suggestions on servicing or repairing it? I didn't see much when I searched the forums. Thanks!
