Top Ten for why the electric motor won't work?


After replacing the sprague bearings on the Cat Pump for our Duo 60 Dessalator, now the 24 volt motor won't run (it's always something isn't it?).  I'm going to take off all the connections and shine them up, but they look fine to me now; no rust or other gunk visible.  It ran fine up to the time of taking the belt off.  We even ran it without the belt momentarily to confirm the direction of rotation for the one-way bearing and it was fine.  I d on't see a fuse at the motor anywhere.  There is a "box" attached to the motor that the red battery wire connects to that I suppose is connected to the control panel "24V" switch to start it.  

So, would anyone like to suggest things to check?

1.  Power to the motor with the switch "on".  

2.  Clean the connections.

3.  ???
