Can I use a 12 volt battery to start my 1914 in the coil box battery position? Thanks, John
12 volts just to buzz the coils? I donít see why not. The magneto at full RPM puts out over thirty, IIRC. If youíve converted to an electric start hogshead then 12v can be hazardous to your starter.
Yes you can use a 12 volt battery to fire the coils making it easier to start a hand cranked car. Just donít let the coil cycle continuously. This Iíll heat up the primary winding and cause the tar to ooze out.

When Brent said,
"just don't let the coil cycle continuously"
I'm sure he meant when the engine is not running and leaving the ignition on.
T's start and run fine on 12v all the time.
My car (with no mag) runs way better on 12v than it does on 6.
Thank you for taking the time to answer my question, I appreciate your response! John
My buddies TT has big alligator clips on the "battery" wires up in the cab. He uses the battery from his 18V cordless drill to fire it.
Then switches to mag. If it's behaving. :-)
I've been using small 12 volt batteries for years to help me start my '13s. They work much better than a 6 volt. They are slightly bigger than a Model T coil.
