Farmall 100 change from 6 to 12 volt?

Probably need to change the lights over also.

Thanks

Just some advice, Tim K.

If you go to the left of this screen and under "Research & Info" and go to Articles. Under Maintence and Mechanical Information there is a paper titled "Converting from 6 Volt to 12 Volt". This is a very good place to start.

My 6 volt alternator on Super A is absolutely the best working one I have. With that one all I did was change from pos to neg ground, add the alternator and the excite switch. Now heading into it's 11th year it has been absolutely trouble free, even the same 6 volt battery is in the tractor. It started this past winter several times at 0 degrees or lower, and started very quickly I might add.

I haven't have a change of heart Randy, just got tired of telling people what to do. I try now to curb myself into just telling people how to do it. You were one of the few people who actually listened. For every Randy there has been a hundred where it went in one ear and out the other. I trust your system is working well. Good to see you are keeping an eye on me. Make note on the above, I said TRY.

I also go for soldered on ends on my cables and 1 gauge wire. When cables start looking a bit on crappy side after 10 years or so I turf them. Many many good batteries have been wasted because of poor cables.

I had lot of starter troubles with a 6.2 Chevy diesel. I went through one a year when truck was new. I moved the batteries side by side and wired it up with 1 gauge same type system as used on highway tractors. The last starter went 6-7 years. Poor power supply very hard on starters. On a 100 hp John Deere, around Christmas was a bit sluggish starting, 12 year old machine, batteries 6 years old. I replaced all cables with heavier than original. Got two more years from batteries, and that machine was being started every day in sub 0 weather with out block heater.
