Thumbs up Re: 12volt conversion question ballast resistor

Before I post a question, I search. So far, everything I've wanted to know has been covered before, usually several times!

I was looking for a coil and saw this interesting post and I had to comment. I've never heard of tapping into the battery case to get 6 volts, pretty ingenious! You really do learn something new everyday, thanks Purdy Swoft!

I counted off cells on top of the the tar top battery and installed a self threading type screw into the plates . I ran a wire from this screw to the radio.this rig gave six volts instead of twelve so as not to ruin the good radio. I changed out the bulbs. this was a popular thing and had been done for years. It was the older guys that showed me this stuff when I was a teenager.. I'm running our roadster 12 volt with the original generator and love it . I've had no problems with the roadster since it was done in 06. Low amperage high volt doesn't create heat the same as high amp low voltage. I grew up when cars were mostly all six volt and I remember lots of problems. parking on a hill was common so you could roll off to crank in cold weather . Eight cylinder engines could crank on six volt but I've seen lots of them that sometimes wouldn't crank. The batteries would run down pretty quick if many mistakes were made trying to crank them. ights were dim unless you ran an eight volt battery. We just don't see much of this stuff on cars with 12 volt. I remember that the headlights were brighter and they started quicker on even the first 12 volt cars with generators. I really prefer generators but realize that in some cases an alternator is the practical way to go . Twelve volts is certainly not a sin in any case.
