I recently purchased a CA Allis with 6 volt system. The guy I bought it from said I could install an 8 volt battery for easier cranking. Is this possible, and is it safe for the charging system and lights, etc.?

Yes, this can be done if you do all the right things. Your generator needs to be equipped with a regulator that is adjustable. The generator typically can get up to the 9 volts required to keep the battery charged. I've got a tractor that I run on 12 volts with the 6 volt generator but that is really pushing it (need to get an alternator for it). And you need to get some additional drop for the coil. Since it isn't much drop, there are two ways. Autozone, NAPA, etc offer resistors for ignition. You need one of about 3/4 ohm. One ohm might work all right as well. The second way is to get a coil of 26 AWG wire. It has 55 ohms per 1000 feet. You would need about 20 feet of wire. If you use bigger wire, you'll need more of it. When the length is right, and the engine is running, you should have about 6.5 to 7 volts at the poitive side of the coil. I'm told the lights can handle the extra voltage.

I bought a 1952 Ford car with an 8 volt battery in it. It seems to work fine but I haven't yet checked to see if the voltage is right. It does turn over better. I haven't decided yet but, so far, I'd rather it was still 6 volt.

I would stick with the 6 volt system. As long as the electrical system and your battery cables are in good shape and all connections are free of corrosion, you shouldn't have any problems. Battery cable condition is super important with the 6V systems. When in doubt, renew them... Steve B.

NO, I tried a eight volt battery in my WD45 and it killed the coil.the elecrical system can not handle the xtra voltage.
