Default Looking to the Legends for help

Ladies and Gents,

I wanted to reach out to this board in hopes of tapping in to the expertise that is here. My father has a 1930 Special Delivery Woody and was in the process of restoring it. He did the outside really well and then went to upgrading the 6V positive ground to a 12V negative ground. Unfortunately Alzheimerís has advanced to a point where he simply canít remember what heís done to it on a day to day basis. My hope is that I can help get this car up and running so he can have a few more memorable rides in it before itís too late.

Sorry for the sob story, but was hoping you could provide guidance to a relatively mechanical novice to start undertaking this task. Your guidance is much appreciated.

Can not help, but hoping you get the help you need and are successful. In 2011 I was in a similar situation with my Dad, and was so disappointed when he passed away before I got the A running enough to take him on rides.


Wishing you the very best.

I have posted this info many times on this board over the years . I last posted it on this thread , Question , simple starter motor conversion to 12 volts . I do include info on converting to negative ground . Check out post number 14 for every detail about converting to 12 volt negative ground !!!

How far did he get on the conversion? Maybe the quickest and cheapest way to get it running would be to leave it 6 volts positive. Does he have any friends that could stop by and give a status of the conversion and decide the best way to proceed?

There is NO cheaper -easier way . If the system is still original and no wires have been cut, all that is needed is reversing the wires at the ammeter ,coil and battery .The battery will need to be changed to 12 volt and the battery cables connected as negative ground
. If a person wants to run the original coil, a ballast resistor will need to be connected to the coil . On 12 volts, I use a three OHM coil and no ballast resister will be needed . This simple upgrade is nowhere near rocket science . With the very simple instructions that have been given , anybody should be able to make this upgrade . The guy has stated that he wants to convert to 12 volt negative ground . Trying to make things more difficult is usually the problem .

Here;s the direct link to Purdy's post:

He nails all the major points, but he forgot the horn resistor and all the bulbs.

He mentions the headlight, not parking or tail and stop lamps. If staying with generator - repolarize generator after conversion to positive ground?

I didn't forget the bulbs or a horn resistor , I just figured that was common sense . No harm meant . I did forget to mention repolarizing the generator . To repolarize the generator it is necessary to touch a long enough wire to reach both posts of the cut out and holding it there for a second or two . Repolarizing the generator can only be done with a cut out in pl;ace . Any attempt to repolorize the generator if a can style voltage regulator is in place of the cut out will damage the voltage regulator .

Hi Purdy,


Hope I did not come across poorly with my posts. I noticed this was post # 3 for him, and his post said he was a novice. So I chimed in, seemed he may need all the info/advice he could get.

There was no harm in the mention of changing out the bulbs . I just figured that every body would know this fact . Why else would 12 volt bulbs be offered , same for a horn resistor .Some of the reproduction horns will operate on either 6 or 12 volts . I'm just getting old and tired and trying to keep unnecessary typing to a minimum when possible . Just my thoughts !!!

Thanks Jim , You are a good guy !!!!!!! We need more people like you in the hobby that can picture and understand a simple upgrade in their minds eye .

Most of the people that convert to 12 volt negative ground use the 12 volt negative ground alternator that is offered in the model A catalogs . The 12 volt negative ground alternator puts out more AMPS for the brightest headlamps. and won't need to be repolarized to operate on negative ground . An electric shop could repolarize an alternator but it won't need to be repolarized because it is already negative ground . I am one of the few that runs the original generator on 12 volts .

We should add that an electric w/s wiper motor, if present, needs a dropping resistor as well.

When explaining to a novice you need to mention every detail. What's no-duh to us is a confusing mess to the uninitiated.

Special Delivery,
Try contacting the Diablo A's of the Model A Ford Club in Concord, CA. There are several members that could give you the information you need. I would suggest Bob Grady.
