for Gerald J and 35 A or anyone about generator

Fer sure you gotta have a 12 volt VR regardless to charge that 12 volt battery. Like my friend Gerald noted its marginally possible to charge a 12 volt battery using a 6 volt genny with a 12 volt VR but thats NOT the best or engineering correct method nor will it set the world on fire with any high charge rate.

If you go the generator route versus an alternator Id EITHER just get a Delco 12 volt genny (they look same and same size as a 6) or you could take an old 6 volt to a genny shop n have it rebuilt up to a 12 volt.

Im NOT an altewrnator fan on old tractors TRUE they charge MUCH BETTER but they look like crap on an antique tractor in my opinion lol

The old style LHBD 4 position light switch can still be used for bright or dim lights control but the Low and High charge positions arent wired in or used of you use a full fledged 3 or 4 terminal Voltage Regulator. If you use a 3 terminal (BAT ARM FLD) VR, BAT on VR wires up to the Load (NOT battery/starter) side of ammeter,,,,, ,ARM wires to gennys Arm post,,,,, ,FLD wires to gennys Filed post. Polarize the genny before you start her up.

If you don't want it to be original, its hard to beat an alternator, because the alternater (once its started charging if 1 wire) will charge at much lower engine speeds and because the alternator diodes make a perfect cutout it never discharges the battery with reverse current when running slow.

I also know that with a GOOD regulator, that a generator will do an adequate job and be original. My MF-135 had a new regulator on it when I bought it 20 years ago, but it didn't charge right. I tweaked the voltage adjustment and its been working fine ever since. One time I thought the battery was going bad, but it was the starter brushes that went open after I'd moved that battery to my '65 F350 and ran it there several years. This year I ran a 10 amp electric sprayer pump several hours a day several times and the generator kept up. And that sprayer pump was running continuously reecirculating to stir the spray mix when it wasn't actually spraying and I used it to inhale parts of the spray mix too.

Several say its worth the added wires to hook up a 1 wire alternator with 3 wires, then it doesn't need goosing to start charging. I have a 1 wire alternator on my JD 4020 and I with the smallest available alternator pulley it takes about 1600 engine RPM to start charging, then it charges down to 450 RPM or slower. I also have an ammeter added so I can tell what it is really doing.
