MF 35 - Alternator problems

Stig Flattum I have a problem with my 1959 MF35, its not charging the battery at all. The battery is quite new, the generator and the voltage regulator was replaced last winter. The tractor still have the 12V DC system. It was charging after that, but in my opinion it did it too little and too late (by reading the ampmeter).

The electric system is not my speciality, and I hope there are some out there that can tell me where to measure etc, so that I can find the problem. Its a bit expensive trying by buying new parts bit by bit :-)

Thanks !

Big Dean I was a mechanic for MF dealers for 27 years the way I always check to see if it was a bad regulator or genertor was by groundine the F or field termminal on the generator. If it shows a full charge on the ammeter with the engine running at 1,000 to 1,500 RPMS Your voltage regulator is causing your problem. Sometimes if the ground cable is not contacting good it will cause that problem also.
Stig F. Thanks a lot for your reply !

I tried it, but still no reaction on the ammeter. But when i connected the wire to the terminal again, it suddenly started charging.
