I purchase a Ford 8N some time ago. I removed the 6v battery without noticing the way the battery was hooked up. Do you hook the red cable that comes from the stater/solenoid to the positive post on the battery or hook it the neg post. I have forgotten most of what little knowledge I had about this stuff. If someone respond's to this please detail the information.
THANKS IN ADVANCE.

The old 6 volt 8N Fords were Positive Ground.

If it has the original generator/regulator/6V battery then it is a positive ground system. If it's converted to an alternator and is 12V it is a negative ground system.

The n's all left the factory 6 volt, positive ground and are best left that way. Hook the red (ground) cable to the positive post of your 6 volt battery. If the tractor starts good with the factory 6 volt system, you know the engine is in pretty good shape and has good compression. 12 volt conversions were often done to help worn engines start easier and are a "red-flag" to most collectors.

12V conversions were also done because trying to keep the six volt battery charged with a generator could be a real pain in the rear, especially in the middle of winter!

Does the red cable come off the solenoid.

The battery posts are different diameter, positive is slightly larger. Match the cables to the size of the posts.
