6 volt system question

cjackman · May 7, 2011

I was thinking today as i got my old silverking out from storage today. Ive always had waht seems to be a hard starting tractor. Everything is good and clean and tight and has new ignition componants. Anyways, ive started it with a 12volt in a pinch and it fires up a LOT easier obviously. Dad said he thoght they made a 9 volt or somethin that i could use to get a little extra juice and not harm the electronics. You guys ever heard of it???

I've heard of people putting 8 volt batteries in their 6 volt tractors to get a little faster cranking speed but the problem is the 6 volt generator won't keep the 8 volt battery charged up.

they made and still do make an 8 volt, has 4 caps instead of 3, they do give more cranking power, but the 6 volt generator won't keep it fully charged, if you have the older voltage regulator, they can be tweeked to help.

Yeah he prolly meant 8 volt. Charging doesnt really bother me as it is just basically a toy as long as i aint burning up the starter and generator. Where can i pick one up??

If it has a magneto just us a 12V battery and disable the charging system. Just charge it now and then with a battery charger.
If it has points and a coil, it is worth redoing the system and converting to 12v.

The issue is easier than replacing a battery with added voltage. An experiment can tell the tale and is free. Those Chrysler engines cranked and started well when in cars, so they should do it well in tractors. The issue is usually voltage drop in the wiring. 6volt systems take almost twice the amps to crank as 12 volt. Thus it needs heavy bat and ground cables.
The experiment is to use a quality set of jumper cables, or an additional battery cable, to boost the carrying capacity of the cables.
Use one Cable (#2 gauge is fine, even #4 gauge will tell the facts.) to go from the ground terminal of the battery to ground, and the other cable to go from hot to the starter switch. Start it. If it spins much better, it is small cables causing it. Replace with welding cables 00gauge or at least Ogauge, and it will be fine. Jim

If your tractor has a mag.and no lights. You could put a 8 volt battery in it and use a 8 volt alternator.

most farm and home stores, TSC, orschlen, and I had napa order me one.

Why would you put an 8 volt alternator on it? I would leave it 6V or convert it to 12V.

If you go with 8 volt you won't have to change anything in the system & have more cranking power.Or you could put a 6 volt alternator on and change nothing. The cost of switching to 12 volt cost more than 6 or 8 volt. The engine in a silver king is not that big and should turn fine with a good 6 volt system.
