Ford 3000 alternator conversion

I am looking for some help with a C model Ford 3000 that has been worked on by many people over its life, none of which used oem parts or kept any records. I have given up on restoring the generator system, and I need a basic alternator kit that does not have to have a tach. I do not need any gauges or lights, as most are not there anyway, I just need this ol girl to run for another year or so till we get a new tractor.
I found one on Yesterdays Tractor for 108$, but when I called to see if it would use my old voltage regulator, they could not answer and pointed me here. I have a suspicion it is faulty because when I hooked it up the generator started spinning (fan belt needs tightened too)! Any help is appreciated.
 
If YT is selling it as conversion kit, is is a near certainty, that it is a one-wire 10SI with built in regulator, so you can trash-can your reg.
 
Most 12 volt conversion kits use an alternator that has an internal voltage regulator and you do not need to use the original external regulator with them.
 
If your tractor has a charge indicator light you will lose that function if you get a kit with one wire alternator.

To connect a 3 wire Delco with internal regulator, loop #2 pin to output and take the lamp wire from the generator or regulator and connect to #1 pin on alternator. Alternator should begin to charge without having to rev the engine
 
(quoted from post at 17:06:11 10/04/17) If you can weld even a wee bit you could
make your own mounting bracket and buy a 10
SI Delco from Napa or Oreilly's, etc for
about $50.

Thanks all. I actually started to make a bracket myself, but time is worth more than the extra 60 bucks for the kit. Also with the loader, it is a bear to work on. Just curious if anyone knows the reason for the generator getting hot or turning.....even with the key off. I had a similar problem with an old massey several years ago that I was helping a fella with. It got very hot after working on the wiring.
 
There are a number of different possibilities for the generator motoring when connected. Most likely cause is that it's hooked up incorrectly. If current is flowing trough the generator because it is hooked up incorrectly then it will get hot also.

Why worry about the generator if you are looking to convert to an alternator?

If you're looking to just keep it running for a year while you save up for a new tractor you could save yourself the cost of the alternator kit and get rid of the charging circuitry altogether and just put the battery on a trickle charger between times that you're using the tractor.
