The Stovebolt Site Forums The Shop Area The Electrical Bay Ignition switch for a 1940

I'm converting over to 12v and I have the original ignition switch that has the metal housing that runs to the 6v coil.

Is there a way to use the original ignition switch or do I have to purchase a new one?

InMy40's,

There should be no need to use any other switch...the stock switch will work fine. The ON function will power the 12 volt coil just as it powered the 6 volt coil.

If you are going to use a ballast resistor ahead of the coil, this would be addressed with the purchase of a starter switch (the one on top of the starter) that has a bypass function.

This too can be eliminated if you use a internally regulated coil. I think you asked about the alternator wiring in another post. The #1 DA wire could be powered by one of the terminals on the stock switch as well (me thinks).

So, the stock switch has all the functions and capacity you need for the swap to 12 volts.

The problem is the ignition switch is attached to the coil with a metal housing. I'm trying to figure out how to detach the switch from the housing so I can swap to a 12v coil.

Ohhhh, that's right! The anti-theft deal. I'm out of my league on this question. I have seen this posed here before, but I think it entailed chopping, hacking and soldering.

Hopefully some helpful person will be along shortly, sorry.
