Re: Converting to 12 v
First why do you want to convert? Second what year car are you wanting to convert? A good 6 volt system with proper grounding, the correct size battery cables, a good charging system , and a good battery will work just as good as a 12 volt system.

Re: Converting to 12 v
Need to add a voltage reducer to the power wire(s) going to the gauges. The electrical path is from the power input to the gauges to the senders, the senders provide the path to ground. Ford used a voltage reducer when they switched to 12v, believe the same basic arrangement was used into the 80s. You can add one voltage reducer that feeds all of the gauges or individual reducers for each gauge. There have been a lot of past threads on 6v to 12v conversions, here are a couple:

Re: Converting to 12 v
Yes, indeed, a single Ford instrument cluster voltage reducer is all you need.
This is similar to what I am using with the only variation being in the way they mount depending on the original application.

Re: Converting to 12 v
That is similar to the 1966 Mustang Voltage Reducer if you need a model year. This is interesting:

Re: Converting to 12 v
I used a Ron Francis VR-1 voltage reducer to operate the gauges on my '41 but I had changed my gauges to mid '70's Ford.

Re: Converting to 12 v
Mine's a VR-1 also.
Here's Flat Ernie's input. He recommends CVR for accuracy. https://www.fordbarn.com/forum/showt...oltage+reducer Last edited by 19Fordy; 11-06-2018 at 03:36 PM. |
