Will all respect to you. With all respect to maintaining an original 6V system. There is another side to the story which does not include keeping the 6V. Just like we abandoned using outhouses and we prefer indoor plumbing, power steering and brakes, overdrive, Pertronix, turn signals..............
The 12V system has lasted way longer as a good system. Here are a few thoughts. they won't change your mind, but are necessary for anyone thinking of changing and not quite that nostalgic or as pure as others.
For those wondering why convert to 12V as GM did in 1955:
1. No big huge cables required
2. You can buy a 12V battery anywhere.
3. Faster starting, especially in cold weather.
4. You can add accessories, winch, electric wipers, radios, extra lights......
5. You can by bulbs anywhere
6. You can't get a jump start from someone without burning out bulbs and gauges.
7. Automotive is built around 12V systems
8. Testing is built around 12V
9. Aftermarket is built around 12V
10. You can buy a 12V alternator anywhere and cheap......and has way less wiring. You can't buy a generator or Voltage regulator anywhere and cheap.
11. Brighter headlights and tail lights, no need for relays
12. You can charge your cell phone
13. 6V takes twice the current/amps to get the same watts. If you have 50W hi beam headlights, they will draw twice as much current as on a 12V system. I.E. 100W (both headlights) is 100W/6V=16.7 Amps vs 100W/12V= 8.33 Amps. This is why 6V wires/cables have to be so big.
You can run out of amps on 6V. (and have dimming, etc). Then you start band-aiding with relays, voltage regulator tricks or living with it.
14. May take a special harness to rewire a 6V truck.
15. It's so easy and inexpensive.
16. There is no reason not to convert except to prove something...........I don't know what.
