6V to 12V Oliver 77

can start with 12 V battery fine.Now I was told that all I have to do is put a 12V battery on it if I don't run the lights. If I do that I need to put a resistor in that line. I was also told by a man who rebuilds generators that if I change the regulator and the coil I am good. Another one said All I have to change is the battery but might have to charge it now and then as the regulator won't let it charge enough.

Put 12V on and the guage shows a discharge instead of a slight charge. Shows a good charge with the 8V battery on it.

Which way can I go here? Also it has 2 guage wires from battery to switch and I think 1 guage from there to starter. Grounded up in battery box, but if I jump from the battery to the starter it still won't turn the starter over unless it is out of the tractor.

8V checks good with battery checker.

A lot of posts indicate a shortage of 8v battery chargers.

Old is right about the cables and possibly the starter does need attention. You won't know that unless you fix the leads and then/or get it checked out if needed.

12 volts on a poor starter would not be a good idea.

If the gen man was talking about the ignition coil, he was wrong if he meant fit a new one. Connections may need changing (if polarity is changed) but otherwise all that is needed is a ballast resistor in series with the coil supply.

Lights on 12v - change the bulbs.

I would personally keep it 6V. Worked OK like that for years, didn't it?
