Topic: 6-12 volt conversion


hotroddoc    -- 02-07-2025 @ 8:38 AM
  Hello,
I have a 36 Coupe that I am converting to 12V. Do you suggest that I keep the floor starter button or install a starter solenoid and put in a dash starter button or somehow hook up the solenoid the the floor button?

Thanks in advance for your comments

  You'll probably get some push back about converting to 12 volts like "6 volt systems work fine with proper grounds and cables", etc. Ignore them, it's your car. When I converted my '39 p/u to 12 volts I found the easiest way was to use a typical Ford solenoid and to install a standard ignition/starter switch where the starter button was. JMO

  You could keep the floor starter switch. It was designed to handle the amperage from a 6v system, so it will handle 12v just fine.
Keeping it would be one less thing to change when converting to 12v.

  If you convert to 12 volt have an electric shop set-up your starter for use with 12 volts. As is, your 6 volt starter will work but if adapted to 12 volt it will likely last longer. I personally don't know what the infernal differences are.

  6 volt starters have been used in 12 volt systems for many years. The Bendix was occasionally an issue but I ran a 6 volt starter on 12 volts for years with no issues.

  The difference is that a 6 volt starter will spin much quicker on 12 volts, which is hard on the bendix and the flywheel gear. Changing out that flywheel gear is a pain in the keester. Best to convert the starter in the first place.

  6-12 ?
make sure all your wiring is in very good condition,
I have been driving my 37 Cabriolet since 1980 on 6 volts,
if you are having problems, check your grounds and correct 6 volt battery cables
if they are 12 volt cables, you will have problem,
recently I had a problem which I thought it was a starter or battery it turned out to be the starter switch solinoid
you will have to deal with your gauges and charging system, when changing to 12 volts
to me it is not worth the time and money,and other problems
if you need to operate something on 12 volts use a seperate battery directly to what you want to use, CB GARMIN other ?
12 volts masks the REAL PROBLEMS
