  • 12 volt wiring diagram?

    Hi all,

    The restoration continues... does anyone know where I can find a complete vehicle-wide 12-volt wiring diagram? I've been searching all over the web and I've found several parts of the info, but not a complete one and a couple conflict with one another. Any assistance is appreciated. Thanks.

    If we are talking about a Model A wiring diagram and if you have one for a 6 Volt system, it is the same for 12 volt. If you convert to negative ground just change the symbols for the battery on the diagram. Most Model A manuals and parts catalogs have wiring diagrams.

      The wiring diagram would be the same except that the battery terminals are switched as are the coil primary leads and ammeter leads.

        And remember, you CAN use a 6 Volt Model A Generator, to power a 12 Volt System!

            How much are you changing it from stock? As mentioned the wiring is the same for 6 and 12 volts IF everything else is stock.

              Hi Mike,

              I'm doing a frame-up restoration and decided to use all-new wiring as part of the job, so I was looking for a reference that had all of the wiring including the differences between the standard 6v and 12v installation. I looked around some more and found a great write-up and diagrams at

              http://cedarcreekas.org/TechTopics/1...rn_Signals.pdf.

              I recommend that document to anyone doing a total rewire to a 12v system - great call-outs regarding the differences between 6v and 12v. The wiring is in now and I think it's sparking well all the way through to the plugs so I think I'm ok there. Thanks to all for the help. Next issue is that it's not turning over yet, but that's the job for today....

                That is a nice write up on the conversion, thanks for posting it.

                Does anyone here on the VFF belong to the cedar creek club??

                    It's already placed in the tech forum for easy reference.. ( 6v to 12v conversion)

                    to many sticky's tend to clog up a site IMO

                      Can anyone out there know what changes are necessary to the attached wiring diagram if wiring the A for 12 VDC Neg ground?
                      Is there a 12 VDC wiring drawing available?

                      Thanks,

                      Attached is a dwg. from the net that may be helpful. It also shows how to locate a condenser away from the dizzy and up at the firewall. If an oil filled coil is used, the diagram has the terminals facing up requiring a longer coil to dizzy wire....

                      by Packrat
                      Hi, I have a 29 CCPU that runs and drives but doesn't have a wiring harness at all, only enough from the ignition switch to the engine to make it run. The switch is a generic aftermarket one taped to the column. It is 12 volt with a generator and I would like to keep it that way. I have never rewired a vehicle before, but it doesn't seem like there is a lot on these. I don't have a dash panel or...

                      6 volt Chargers
                      by sunnyorm
                      Looking for consensus on good Battery Chargers for 6 volt (mine is Optima)

                      I searched using 12 volt charger (which mine is now) on a 6 volt, but am not sure, if it is alright?

                      Conversion back to 6 volt
                      by popsjohn
                      I am looking at a 1931 CC Pickup that has been converted to 12 volt. What would be involved in changing it back to stock 6 volt system?

                      by Fixitphil
                      When converting my A to 12 volt I've heard that you have to switch the two primary wires on the coil. Which small primary wire goes to positive and which to negative side of coil?
