1 wire alternator

[oregonfarmer]

I want to install a one wire 6 volt positive ground alt on a 200. There are so many it is hard to know witch is best. This tractor has only starter and ignition to power.

12 volt will be a lot easier and more common for parts than a 6 volt. I would go with the 3 wire style less trouble and just as easy to wire up.

Years ago, the late Hugh McKay posted some info about that very alternator. I dont recall much about it though other
than it was expensive. Would be cheaper to just change to 12 volt.

Did you really mean ..6 volt..? Essentially to change it
over to 12 volt negative ground you swap terminals
from side to side at the ammeter and the same at the
coil, add a resistor before the coil and change the
bulbs to 12 volt. That is all, then you purchase a much
less expensive 12 volt negative ground alternator.

For a one wire 12v neg ground alternator, is there any certain brand or description to ask for at the parts store?

Here are a couple pictures of a Denso 1 wire alternator kit for the A, B, C series of tractors that I sell. It's a 12v negative ground system 35 amps and looks and works great on these tractors.

I got mine from Quality Power. They offer 6
volt alternators in positive or negative
ground along with various pulley sizes. I have both types on some of my
tractors and they work great for me and I am
very pleased with them. They are listed for
$145 plus shipping, so they are quite a bit
more than a more common 12 volt. Also if you
really want one they have an alternator that
looks like a generator but those are over
$400

Hey O..farmer on a side note several others and myself
are wondering if you have a few more details on your
post about plugged injector lines. What machine are
they off of and what are they plugged with. I was going
to recommend E85, I have no experience with it but I
heard a lot of people swear by it for cleaning up stale
gas. Here is a link to the post.

If that's what you want to do, there's no reason to let anyone talk you out of it, it will work just fine.

And you don't to spend big $$$$ to make it happen.

If you have a Delco 10SI or can acquire a salvaged one ($5 to $20?) with good stator and rotor windings and aren't scared of a little project you can make a 6 Volt (+) ground unit with a $55 (shipped) kit.

An older (mid to late 70's) 45 Amp unit from a basic car or pickup without AC would be a good candidate to start with and MORE than adequate for your basic tractor.

Most likely they are all the exact same alternator, just different packaging and different prices, depending on how hungry the seller is, how greedy the seller is and/or what the seller offers with regards to service after the sale.

So you can go with the cheapest option, but don't expect anything from the seller if you have a problem. You can also go with the most expensive option and not get anything from the seller if you have a problem. Then again the cheapest seller might bend over backwards to help you. You just never know.

If any of the sellers are ones you've dealt with before or have heard of (and have a good reputation), it might be worth it to go with one of those.
