New Ford 2000 Owner with questions

I replaced it and now need to make sure it's working. I polarized it as was told by the store I bought it from.

I connected the ground wire to the alternator. I then connected a wire to the field connection of the generator and briefly touched the 'negative' terminal of the battery. There was a small spark. (The tractor seems to have the "+" connected to the tractor's chassis so that's why I touched the negative terminal with the wire.)

So how I can I check to make sure the generator is working? With car alternators, I simply measure the voltage across the battery to make sure it's 12V with the engine not running and 13+ V when it is. But I tried the same with the tractor and it seems I get 6 Volts when not running and then "0" volts when running. That seems awfully odd. I tried both DV and AC setting on my voltmeter.

To get a generator you will need to know it is a 1964 2000 w/4 cylinder engine. You will also need to know if it is gas or diesel because the gas is 6v and the diesel is 12v. This is all based on the fact that no one has done any modifications to it in the past.

Are you sure the genny died? Any chance it could merely be the regulator?

Might be way cheaper to rebuild than replace.. or simply repalce reg.

Do a motor test on it to see if the genny itself is good.

Disconnect genny from reg, ground genny case, jump power to armature and field. if genny spins, it should charge.
