Hi all,
It works!!! A '76 spitfire gave up it's carbon brushes from the garbage
wiper motor. Turned them sideways trimmed an arc for maximum contact and
they fit the '3 brush holders perfectly. Snug and plenty of brush space.
Put it all back together and turned it on....it ran. Turned the switch off
and it parked perfectly. Thinking this was a fluke, did it 3 more times and
made sure my youngest saw it to make sure I wasn't dreaming.
Randall, Kent, Geo et al a huge thanks.

Okay, 12v across the terminals. I turned it on again and with a little
fustration tapped the housing with the handle of a screw driver, it moved!!
Not much but it moved. Then stopped, tapped again, moved again. I'm now
thinking bad contacts around the brushes or the arms?

And did you check the voltage across the terminals (not just across the
wires) ?
If you're getting 12v there, then either the field winding is open (I was
wrong before, 12 amps would probably not blow the fuse), or the motor is
mechanically jammed somehow.
