If my Farmall M has a belt generator and a positive ground, This makes it a six volt correct?

I’ve had had trouble starting so tonight I am putting on all new battery cables and a new cable to the starter (the cable to the starter was worn badly. I also want to buy a new battery. When I bought the tractor it had a small 12-volt battery on it. I will try the same batty after I change the cables. Any pointers to make sure I don’t fry something.

Thanks for your help

I looked at the generator last night and it was a remanufactured 6 volt from beatrice,Neb. I didn't notice the coil.

Yes, John the lights were burnt out so prior to the tractor starting redid the wiring of the top lights down to the steering wheel. From there I put 12 volt lights in because the battery was 12 volt and the dim/high switch.

I've replaced the cable to the starter with 1 guage and placed the same 12 volt battery that it came with back on. Hit the foot pedal and the postive battery cable just popped.

So I guess I will put the 00 guage battery cables on and put a 6 volt battery. Thanks for your help I will keep working on it until it works.

Thanks for your help-scott

If that coil is 6 volts. You may have fried it unless there's a ballast resistor installed to drop the 12 volts to 6. Hal

Where would the ballest resistor be located, if there is one on this tractor. thank you. Scott

The ballast resistor should be between the ignition switch and the coil. Go to page 3 on this forum & look for a Super A conversion to 12 volts posted by Mark Herbert. Then click on Bob M's response just under the original posting.
He has a wiring diagram displayed that shows how
a tractor being converted to 12 volts is wired.
The ballast resistor is shown in that diagram.
Have a nice Thanksgiving. Not much left of it now. Hal
PS: He has a list of material to make this conversion too.

Fisherman, just because its Positive ground, that dont determine whether its 6 or 12 volts, most old tractors, 6 or 12 volt, still used Positive grounding.

Also, the genny will work at EITHER ground so long as its Polarized.

If it had a 12 volt battery in it, I would suspect it may well be a 12 volt genny, I guess you cant find any labels on the genny or Voltage Regulator??

You asked about not frying something, you may wanna see if you can determine if you have a 6 or 12 volt coil and if theres any external Ballast Resistor in the ignition circuit wired ahead of the coil?? If its a 12 volt coil or you find an external ignition Ballast Resistor, thats a darn good indication she was converted to 12 volts, although it still dont tell ya if they changed the genny. If you put 12 volts on a 6 volt coil without the ballast, the coil will run very HOT and the points will burn up quicker, so that may be one of the dangers you need to look into. Other then 6 volt lights would burn up on 12 volts and possibly damaging a Voltage Regulator, youre probably not gonna do much more harm if you connect 12 volts on a pure 6 volt system.

A 6 volt coil would read around 1.25 to 2 ohms or so between its lil + and - terminals while a 12 volt internally ballasted coil will read more like 2.5 to 3 and over if you have an ohmmeter handy.

Let us know how things turn out

Probably. The Delco generators are color code. Red background tags are 12 volt, black are 6

It all depends on whether you have a 6v or 12v belt on your generator.

There are 12 volt generaters also.

do they still have a positive ground and would it say on the generator somewhere if I can still read it? Thank you- scott

Read the tag on the generator housing; it should say 6 or 12 volt.
Remember to polarize the generator before starting the engine. Momentarily touch the Battery wire to the armature terminal; just a spark is enough.
