This subject is well do***ented on this site. Look under technical and do a search. Thank you and good luck!
I have changed a few but I wouldn't do it again. 6V worked for 100 years and will work for you too. It is easier and cheaper to fix what is wrong, rather than replace half the electrical system then still have to fix what was wrong.
I guess it must depend on the car then. I've done a few and they were not that bad to do. Thats about the first thing I do to them anymore. Although I usually put a new entire harness in while I'm at it.
A couple budies did theres, it was pretty simple.... Put a 12 v battery in, put a pretolite alternator in, switched all bulbs to 12 volt, switch brake switch as well. and your off.... Starter was never changed, and was still good 10 yrs later.... What annoys me about 6 volt, is the slow crank of the engine. It seems right when it isn't gonna start, it starts. That's dries me up a wall
^^^^^^^Why change the brake switch? They're neither 6 or 12 volt and, if they were, a 6 volt would last forever with 12 volts running through it.
I change the alt, battery, coil, all the bulbs, add runtz voltage regulators to the gauges. and skip the ameter in favor of a voltmeter. And I think thats it, I may be forgetting something but that will get you started. I usually change out the complete wiring harness too they are always old and questionalble anyway.
I wouldn't use a runtz , I hear when the die they can send the full voltage 12 v to your gages. I'm doing mine and from what I researched the best way to go is to use a ford instrument cluster voltage regulator, they were used to the 70s and are still easy to fine. I got mine from rockauto for 39.00 bucks but may find one cheaper STANDARD MOTOR PRODUCTS Part # VRC604
