A few weeks ago, after sitting for some weeks, my
battery in my 1948-early '49 8N needed a recharge.
After recharging, it lost its charge again the
next day. After cleaning the batter cables it
seems to hold its charge now.
However, the Ammeter had not been working so I
decided to swap that out at this time (before
Winter). The new Ammeter did not work so I
decided to swap-out a new generator (which I had
acquired a few years ago, but rebuilt the old one
instead) and while I was at it, replace the old
wiring harness with a new one that I had purchased
some years ago with the intention of doing that
someday in the future. Also, inasmuch as I was
not sure if the battery was charging (suspected
generator, no working Ammeter to know for sure), I
opted to replace the old Voltage Regulator also.
Long story short, with new wiring harness, new
generator, new voltage regulator, the tractor will
not start. With key on, and a spark plug attached
and rounded to the engine, no spark to the plugs.
So, as a test, I put the old voltage regulator
back in...still no spark to the plugs.
When I opened the the new wiring harness, I used a
continuity device to make sure of correct wire and
labled both ends of each wire to prevent incorrect
wiring.
I followed the following wiring schematic
faithfully:

As far as wiring goes, the only things I have not
replaced are the ignition switch and the terminal
block.
Any suggestions on how to determine why no spark
at the plugs?
