Topic: 6v to 12v conversion


HenryDominguez    -- 04-08-2015 @ 9:14 AM
  I'm converting my '40 Ford to 12v. I bought one of those electronic voltage reducers, and it works fine. However, it sends a constant 6v to the battery gauge, which means it will always read "charged." How do I hook up the battery gauge so that it will give me a true indication of battery state of charge?

  I assume you are talking about a volt meter. Attach the hot side to a power scource that reads 12 volts when the ignition switch is turned on, and the other side to ground.

  you will have to add a new 12 volt, voltmeter, the original 6 volt one will not work, I tried. I finally mounted mine in the glove box, so I would not have to look at it all the time.

  Henry,

Alan is correct in saying that there is no easy way to make the original meter work.

Cliftford's solution will burn up your 6 volt meter.

You may be able to use a 41 truck ammeter in your cluster to indicate the charging rate.

  I thought that would be the case. I'll buy a 12v voltmeter and place it in an inconspicuous place. Thanks for the advice.

  Henry,

I use a 6 volt meter that plugs into my cigar lighter, they also sell them for 12 volts.

  I guess I didn't read your post closely. I was assuming that since you changed to 12v, you already had a 12v volt meter.
