I have a 1952 Ford 8N. Recently replaced the generator, coil, plugs, wires, points, condenser, cap, rotor, battery, voltage regulator and wiring harness. Tried to start today - it cranks slow and will not turn over. Any suggestions as to what could be the problem? Everything is 6 volt. I am getting gas flow to the carb. Also - should the battery be positive or negative ground. Right now, it is positive ground - that is what the F04 manual says it should be.

Have you checked for spark? Just because you replaced all those parts doesn't mean you have spark.

Is this the first time that you have tried to start the engine since you replaced all those goodies? If so, I would go over all the connections and check the battery. Perhaps it is low. If this does not yield any improvements, then it is time to measure the actual voltage getting to the starter motor. Obviously, this is where a VOM comes in handy. You should get around 5 volts at the starter terminal when cranking the engine. You are probably not getting this...

Can I get a VOM at Radio Shack? Where would I attach it - on the starter solenoid?

Yes, you can. You would connect the negative lead to the starter side of the starter relay (solenoid) and the positive lead to the metal case of the starter. This will also measure return losses.

Matt,
Yup, positive ground is correct. One frequent cause of the symptoms you describe is a poor ground connection. Many ground wires have been replaced with automotive types which are generally too light. Ground should be 1 gauge or even 0 gauge, and the connections between battery terminals, chassis ground and starter very, very, very, very clean and secure.
