old: I tend to keep these things rather simple. My first alternator conversion was my Farmall Super A. I had a new 6 volt battery and the old generator packed up. I asked auto electric shop guy to get me going quick. He said, " quick with that old generator will be two weeks as I don't have the parts, quick for an alternator will be 5 min as all I have to do to a new Delco 10IS is change internal wires to make it charge 6 volt.

At 6 volt I was faced with finding a way to excit alternator, without diodes or resistor lights. Remember quick was the order of the day, not experimenting to see what lights or diodes would work. I hooked battery to main terminal of alternator. He also gave me one of those pigtails that plug into side terminals. I hooked one wire to main terminal and the other I left as a jump wire I could touch on frame to excit alternator. It worked great.

A few days later when I had a bit more time, I made this more perminent. Since the SA had an extra wire in harness, I hooked it to my jump wire, drilled a hole on dash for a push button type switch and grounded the open side. Now all I have to do when I start tractor is hit that push button switch and system is charging. I watch the amp gauge as I do this, thus I know what is happening. Amp gauges don't show a charge very long after starting a SA that fires up quick. That was almost 13 years ago and the system has worked perfect ever since. No fooling around with those damn diodes or lights. I have since converted 130 and 140 to 12 volt alternators and used the same type push button for exciting alternators. I had a light and diodes on 130 for awhile and something was always not working. I soon said the He## with that.

An interesting note, quite often these start charging on their own without pushing button even at idle. 140 about 90% of time, SA about 50% and 130 about 20%. I wouldn't fool with being fancy, most of these old girls need warmup time anyhow, you may as well have something to do during that time.
