Tech: 6v to 12 v starter

I am converting my Dodge Flathead 6 from 6 volt to 12v. My question is, 1) Do I need a new starter or will the 6v one work, just spin faster? 2) Do I need a 12 v specific starter? 3) Where do I find a 12 v starter for this engine, havent had any luck?

Thanks!

 

6v starter is fine

 

I have a 6volt starter on my 1952 john deere and I start it with 12 volts I've been doing it for about 7 years with no problem Pat

 

Have a 6 volt starter in my 52 Willys Jeep and been running it on 12 volts for 15 years now.

 

6Volt starter will be fine.

What can i say 6 Volt start works OK on 12 Volt.
Go for it.

 

You may want to change your solenoid to a 12V Ford style, but the starter is plenty stout enough. Don't forget to put a ballest resistor in the line from the ign switch to the coil. and remember to swap the leads on the coil (***uming you are changing to neg ground)

The other small post on the Ford style solenoid id hot when the starter is cranking. It is usually used to power the coil (byp***ing the resisted circuit) with 12v while the starter is engeaged. When the key is released to the run position the coil goes back to getting its power throughthe reisited lead. 12V to the coil will over heat it in short order.

If you are switching grounds you also want ot swap leads on the ammeter to recognize the new flow direction.

 

Ditto to the above about being good for 12, but prolly a good idea not to engage the starter for extended periods.

 

Did this on my 601 Ford tractor a while back. No problems.
