Hello MMD,  Restoration of my new art case Knabe Ampico grand is well
under way.  I connected up the motor and the pump goes backwards --
the arrow on the pump case tells me this.  I tried swapping the wires
and looking for other ways but it goes the same way each time.  Does
it matter?  The pump still works.  Is there something I am missing?
