Doc. The 6 volt starters seem to take 12 volts without too many problems, provided they are not cranked over for long periods of time, and given time to cool between starts.

Neither of those attempts to reduce the current (amperage) will make the least bit of difference. It is the 12 volts that may cause problems.

I know a lot of guys convert to 12 volts but I really wonder if it is necessary? If your battery is the largest that will fit; battery leads are the largest cable size you can get; battery to starter leads are connected near the starter, not behind the dash; electrical connections are all very clean and shiny; starter motor and generator are both in good condition, particularly the brushes; engine is correctly tuned; and you have Pertronix ignition, the tractor should be fine starting and running on 6 volts.

I have seen a 6 volt Fergy modified to having two large 6 volt batteries in parallel (6 volt output) fitted inside one rear mud guard with very thick leads to the starter. (The diesel Ferguson TEF20 had batteries fitted inside one rear mud guard.)

Right up to the 1950s Ford V8 engines had 6 volt ignition and how many 6 volt flat head V8's were fitted to military vehicles during the war? Volkswagons were 6 volt batteries for many years. I remember seeing a late 1930s Lincoln Zephyr with V12 side valve engine, starting and running from 6 volts.

Is a 12 volt conversion really necessary if the tractor is maintained and kept tuned?
