[Ford-ferguson] Ford 9N Tractor

[Mike Sloane]

It was very common for the engine on a 9N/2N to be swapped out for a 
rebuilt 8N engine when the old engine died (frequently because of a bad 
oil pump or just plain worn out). The fact that you still have a front 
mounted distributor means that it was a very early 8N engine, which is 
is interesting but not important.

In theory, it is possible to modify a 6 volt regulator to put out the 
13.6 volts needed to properly charge a 12 volt battery, but it is rarely 
done, except in an emergency. At this point, with the odd assortment of 
pieces you have, you need to decide whether you want to return to 
original 6 volts or stay with 12 volts. (Of course you also have to 
consider the lights too.) Unless you are really savvy with this kind of 
thing, my inclination is to take the generator and regulator to a local 
auto electric shop and have them look it all over. Since Ford didn't 
supply a 12 generator for the 8N, someone either modified the original 
or just found a later 12 volt generator that fit (or could be made to 
fit somehow). A common solution to electrical problems back in the '50s 
and '60s was to just abandon the generator/regulator and throw in a 12 
volt battery and charge it up between uses. So it is entirely possible 
that your generator is still the original one, and all you need is a new 
regulator and 6 volt battery. There are lots of "unknowns" here that 
need to be investigated.
