Farmall M Overcharging Problem


[ Expand ] [ View Replies ] [ Add a Reply ] [ Return to Forum ]

Posted by Jim R on July 30, 2009 at 21:57:29 from (209.181.185.49):

I recently purchased a 1951 Farmall M and when I run it at faster RPM the ammeter pegs out to the Positive side. It is still a 6 volt, positive ground system. There is also a small bracket with a small porcelin piece fastened to the top of the horizontal distributor. This porcelin piece has two wires attached to it, one of which goes to the back of the coil. I"ve never seen a device like this on a "M" and I"m not sure what it is for. Can anyone out there tell me where to start to check to rectify the overcharging problem? Could the voltage regulator possibly be sticking. I"m a little electrically challenged and don"t quite know where to start. Any advise would be greatly appreciated.
