Has anyone had ill effects from using an 8 volt in place of a 6 volt battery ? 350 utility.

Years ago I used 8 volt batteries in my IH M and the JD A. Never had a problem. Cranked better and I never adjusted any part of the charging system.

Good 0/1 sized cables with clean connections and a properly working starter and charging system will start your tractor just fine.

6-volts worked for 50 years, it can work for another 50, then 50 more after that!

Just put it in and dont fool with anything and it will work fine. The systems i have used and did other repairs on the tractor the owners have always said they get along just fine. Most of the time a rebuilt starter and good 1ga cables will solve starting problems. Why not spend the money and get a factory rebuilt starter and go. They sure worked when they were new cause how did we make it to get where we are now.

The il effects include possible shortened life of light bulbs and also of the battery due to not keeping it charged. You can make an adjustment to regulator by bending the spring perch of the voltage cutout relay (the one with the thin wire).

If the starter, generator, cables, connections, etc. are good, a 6 volt battery should start a 300U. If the engine has been tinkered with to the point of more compression, then 6 volts may be marginal.

I ran 8 volt batteries in my M and SM for about 15 years. Each had oversize high compression pistons, and 6 volts was not enough to spin them comfortably. No problems with the 8 volt battery in either tractor, and the charging system kept up just fine with no modificatons. I eventually converted both to 12 volts.

im with tom on this one. The charging circuit will not keep up. I would stick with a good 6v system, or go for a 12v conversion, unless u want originality. If you got an old 12v alternator and a 12v coil, and some headlights laying around, the conversion costs nothing but about a days work to fab up a bracket and get her wired up. The difference is night and day. Now I know my system is running properly, nice bright headlights, cant beat that!! Also could hook me up a fan to keep me cool, or even install a radio easily!!. My alternator has a Lifetime warranty on it, so I'll never have to worry about that.

If you got the 8 volt just laying around, stick it in there, but you might wanna build a float charger for it to charge when not in use, thats what i did for my 6v cause my gen was shot.

I put an 8 volt battery in my H and grounded my field wire with a switch in series. Every once in awhile I'll ground it giving a full charge to the battery. I never have to put a charger on it. I've been using her like this now for a few years. Best system I've had for a tractor that could never seem to keep a charge. I would replace again with an 8 volt. I can also tell it has a little more oomph when I hit the key. Good luck.

What do you mean grounding it with a switch in series?

if you ground the fields the generator will charge it's maximum output. but you still need to adjust your regulator to charge the proper voltage which would be around nine volts. i never liked eight volt batteries. they are expensive for what you get.

Run a # 12 guage wire from the field terminal to a switch from the switch to ground.

Field terminal..... ..switch..... ...ground

..... .....= 12 gauge wire

I would like a little more details on this so I can do it. Would you give me the ABCs as to exactly how you did this.

There was a web site someone gave me explaining wich screw shell was the field terminal. Info someone gave me on this site. I just ran a #12 gauge wire back to the control center ( ha ha ) and put a toggle switch in series with the wire and than I grounded it to the body. Someone else said to put the correct resistor in place and I'd never have to keep switching. But I've always liked manual control. When I hit the switch the charge jumps up and the lites get a little brighter. It may burn my battery out a little sooner. But beets throwing a charge on every now and again. Hope this helps

I have put one in my H. The Generator will not keep it charged up. I have to put the 12 volt charger on it once in a while. It works goods when fully charged. However, I am not convinced that a fully charged 6 v works just as well if you have good and proper sized cables on it.

I had a misstatement....I meant, "I am convinced that 6v etc."
