Electrical problem with a lawnboy push mower

Ok, Guys, here goes:
I'm rebuilding a lawnboy d400 engine on a 44 year old mower.
I have the engine all done but can't get spark.
This is a point system and have new points gapped at .016, plug gapped at .025
but here is my question, really. When I put a continuity light from ground to the primary wire of the coil it lights up? It's been years since I've dealt with points so I'm at a loss. If I go from ground to the tip of the condenser i get a light, also.
I'm thinking the windings in the coil are bad? Help.

Here is a link to the points and condenser tests, pay no attention to the outboard reference. Have a good one. Geo

Thanks, Geo, I haven't worked on a point system lawnmower in forever and the manual here will help.

Fixed

Finally got this running. One strand of wire from the primary side of the coil was touching ground and shorted the whole ignition system out.
