This is my first post on here! Still working out the navigations of the site so please let me know if I’m posting in the wrong location.

My 1955 Ferguson to-35 was converted to 12 volt with an alternator. The original tachometer no longer works. Can someone point me in the direction I need to go to find a tach that runs of distributor? Or the coil? I’m very new to all of this but am looking to dive in head first and learn all that my mind with absorb!

Thanks in advance!

The original tach drive was on the back of the generator. There are no alternators out there that have such a drive and no kits that I know of to drive the original tach. Could use any 12 volt auto zone thach that signals from the distributor if you are not worried abut appearances. One other thought is maybe finding an original generator and having it converted to 12 volt if that's possible. I don't really have a good easy solution for you, this is all I can think of.

Is your tractor a diesel or gas? The Standard diesels are driven off the cam shaft via cable. The cables are know to break.

The original system with a continental gas engine was 6 volts. The Diesel was a 12 volt system according to the data I was able to find. There might be a possibility of finding a distributer with a tach drive. Maybe you could use both the tach drive distributer and the tach itself. If your not interested in keeping it 100% stock you could check the junk yards for a 4 cylinder car and take the electric tach out of it.
