Basically you need to asses everything connected to the electrical system, decide to replace it with 12 volt components, or separate it out and feed it 6 volts. You also have to decide if you want to keep it positive ground.
Do you replace the 6 volt generator with a 12 volt generator or do you use an alternator? If you use an alternator you will likely have to remove the ammeter from the circuit (if equipped) as many are limited to 30 amps, where most alternators are twice that.
What to you do about wipers if electric?
what about heater fans? radio? gauges?
There are many ways to answer those questions, and many ways to get results.
When many talk of "conversions" they replace the bulbs, may be the ign coil and **** the rest! That is how most were done, address the easy things and avoid thinking about the hard.
The F$%^ the rest is where you go from something reliable to something less reliable, which was the whole reason for the 12 volt change in the beginning.
With solid state voltage converters you can separate out the stuff not easily replaced with 12 volt and supply it 6 volts, but that requires that you change the wiring from factory, so you have two harness, one 12 and one 6.
All in all, I find it easier to put it back to factory (also looks cooler, being stock) and keep it as it was. It works and doesn't require new or different wiring. Only problem comes if you want to tow a trailer with LED's or swap a trailer between a 6 volt and 12 volt tow vehicle.
Again, no one size fits all answer to the problem. no step by step directions as each case is different
CB, thanks for your input on this.
I bought this 54 R100, with the conversion started. It has a 12v battery negative ground, single wire alternator, electric fuel pump, pertronix ignition, and resistor block. I will leave it as it came. Partly because I do not have any of the hardware to return it to 6v positive ground.
My 55R100 is 6v positive ground, with generator, voltage regulator and bulbs, and I will leave it in tact.
I have not looked at the heater, wipers, the ammeter gauge, coil, or the bulbs, and I will be adding a small radio. I will for sure tackle the easy things, until I hit that wall.
