6 volt booster?

[SamD]

A neighbor was telling me about a way to put on some type of booster or something like that to just juice up the starter to 12 volts during ignition to give that extra umph to start, but then continue to run on the 6 volt system. Does anyone out there know what the heck this is about and any more information about it, is it possible, is it practical, is it worth doing? This is my 1941 truck with a positive ground. Thanks ---Sam

Sam,

I haven't seen one in years, but at one time there was a 12 volt battery available with three posts. From the center post to the outside negative post was 6 volts and between the two outside posts was 12 volts. It was used a lot for 12 volt conversions from 6 volts, but you could keep all the 6 volt accessories by just coming off the center post to ground. I don't know that they are made anymore, but if you could find one of these batteries, you might be able to wire up the starter only for 12 volts. The only problem is, you would have to convert your charging system to 12 volts. Probably a better solution would be to just convert the whole system to 12 volts and keep your 6 volt starter.

I just found in my shop a power inverter/booster. I bought it years ago to run a radio in my positive ground MG. It turns positive grd. to negative grd. and takes 6 volt positive or negative grd. to 12 volt negative grd. Unfortunately, it has a max output of three amps. Not enough for a starter. I have never seen a booster that would be big enough for starter.

Thanks for the replies, We live around a lot of farms and my neighbor said some man that lives around here does the booster thing to 6 volt tractors, I don't know, just wondered if anyone out there had heard of such a thing.
