Question: My Ford Jubilee was converted to 12 Volt and has a generator that doesn't charge. I am going to by an alternator to replace the generator. The alternator on Yesterday's Tractors states "does not include hardware". Wouldn't I simply be replacing the old generator with an alternator and be using the existing hardware or is a kit required? Thank you.

No kit required. With some basic shop equipment, most tractor generator brackets can either be modified or used as a pattern to build new brackets. It all depends on a person's ability and tools. Some kits still need to be modified.

If you are the type that does not fabricate things and
want it just to bolt on the first option in the link is what
you want. It may have wire and a resistor which you already have but the kit is cheaper then adding the upper and lower mounts to the price of the alternator. It also includes instructions!

If you go with the Delco 'one wire' alternator, all you need to do is
connect a #10 wire to the BAT terminal of the regulator and remove the other
wires. Or completely remove the regulator and splice the wire from the
alternator to the BAT wire.
As for the bracket, no the alternator is not a direct fit. You can buy a
bracket, but they are commonly not well made, but would be a start. Having the alternator well mounted is essential. It must be tight, the pulley properly aligned and
straight, and the proper pulley width to match the belt width. If the belt
is a wide belt, you can buy a wide pulley for the alternator, sometimes the
old generator pulley will fit. You don't want to run a narrow belt in wide
pulleys, it will bottom in the groove and slip, or a wide belt on a narrow
pulley, it will throw the belt.

I don't use the Delco alternators anymore. I use the Hitachi 14231 alternators. They have a small foot print and look
much nicer on the old tractors. They wire the same as a 3-wire Delco and that all I would use is a 3-wire alternator.
You can buy them on-line or any automotive store. Just ask for 1979 Nissan pickup.

I'm thinking the NAA and hundred series use the same bracket and generator.
I say that because I have done this on a hundred series tractor so I am thinking it will work on the NAA also.
If you are using the Delco 10SI alternator you can make the generator bracket work.
Take the generator bracket off and turn it 180 degrees to where the front is in the back.
Now with a piece of all thread rod and 4 or 5 nuts that fit the rod you can mount the alternator to where the pully aligns up well enough the belt will stay on.
If you can not picture how this works let me know and I will go outside and take a picture of my tractor.

Have you tried to polarize the generator in an attempt to get it working again. That could be a very simple solution to the problem before you try to convert to an alternator. After I changed my C to an alternator, I learned that I might have scrapped a good charging system, simply because I hadn't polarized it.

If I recall, I might be wrong, its been a long time ago, The
pulley on the generator has to be put on the alternator because
the generator pulley uses a wider belt. Need an impact to get
the pulley off.
The generator was + ground, alternator negative ground.
So the wiring has to be changed, get rid of the voltage
regulator and rewire the ammeter.
I made my own wiring harness.
I think I had to modify both mounting brackets to get the
pulleys to line up.
It's not rocket science. May need a welder to make brackets fit.
Again, not 100%, I've slept since I did the job.

Thank you for your reply and expertise. I've had the tractor for 17 years and it had already been changed to 12v. I am having second thoughts that it is a generator as I disconnected a terminal connection while the engine was running and it quit. But if it was an alternator that wasn't putting out a charge, wouldn't I see the same result, engine quits? I really don't use it too frequently (couple times a month) and the battery generally holds up for two, two and a half months before I have to charge it. Anyway, thanks. Your suggestion sounds a lot less complicated than some responses.

You may be on to something, back in the day those were expensive so expensive we converted them to GM 10DN alternators. I use to stock the conversion plug.

Don't pull the Bat terminal off with an alternator. The battery is a stabilizing voltage control. They can create 100 volts
and do system wide damage as well as danger. Jim
