I am converting my 6v pos ground to a 12v neg ground. It has a ignition switch and solenoid not the oe rocker. Should I change the solenoid or any of the wiring for the ignition along with the regular items (coil batt gen light bulbs etc)? Thanks for any help with this.

Since the solenoid isn't engaged and drawing excess current (due to twice the voltage applied) for a very long time, it "could" maybe might lol last a long time. However, it would be easy to add a series voltage dropping power rated resistor in series to reduce the 12 volts down to 6 orrrrrrrrrr fairly cheap n easy to just get a 12 volt solenoid if and when an old 6 volt burned out.

If changing polarity the coil polarity also needs to be changed as well as any ammeter leads so it dont read bass ackwards.

You can EITHER add a series voltage dropping (12 down to 6) Ballast Resistor to the 6 volt coil OR get a new full true 12 volt coil no ballast required

The old 6 volt starter will work and still turn same direction regardless of polarity, however, it can be a bit tougher on starter drives/gears etc when using 12 volts on a 6 volt starter. Ive done that with no problems however and dont let them crank on and on and on to risk overheating.

New solenoid and 12v coil would be a good idea. Old 6 v generator had a cutout ? NEw 12 v needs a voltage regulator and an extra wire or two..
