MF-50 Alternator

[KevinTernes]

Complete tractor newby here.
I just got a 64 Massey Ferguson gas MF-50.

With a new battery, I measure 12.5V at the terminals with the ignition off. I measure 12.1V with the engine running, lights off.

On the Yesterdays Tractors Electrical System page, I see 4 alternators.

Can someone tell me which one I need? See pix.
Do I need a new pulley or can I transfer the one I have?

Thanks!

That's a generator - Not an alternator.

Well, that explains why what I am seeing bolted to the side of the tractor doesn't look like any of the listed alternators. Thank you Boss!

You can save yourself a lot of work by getting the generator serviced at an auto electrical shop.
