Low ohm reading at power plug is probably the transformer primary- it's normal
Either the forward contactor isn't pulling or it is but there is a loose wire or the contactor is damaged/worn. The problem is an open, not a short.
Can you determine if the forward contactor is pulling? Should make a loud clack like the other one. Is there a carriage switch that selects forward and reverse? They sometimes give trouble. Bad capacitors don't cause this type of problem; both directions would be affected.
Do you have the Smithy manual with schematic diagram? The contactors look different as if one has been replaced already
Testing a system like this under power is a bit dangerous unless you know what you are doing- do you know anyone with some electrical experience you can pay/bribe/extort?
