12v alt on 6v system

[Los_Control]

I am thinking I will switch mine to 12 volts negative ground, I have a new 12 volt regulator. Many say that you can get away using the original 6 volt generator for awhile.

I guess they dont really care what they put out, is the regulator that controls it. And the more you use the vehicle, the more the generator runs and the sooner it will go out.

You can rebuild the 6 volt genny with 12 volt field coils, but so many 12 volt gennies available on the shelf it is not worth it.

you need the 12 volt regulator and all 12 volt bulbs.

The 6 volt heater/fan motor will run really fast, but can use it and replace when it quits.

The starter will work great, replace it as needed.

And as said above, the 6 volt positive ground radio will burn up on connection. Take care with it.

Think special care will be needed if you have electric overdrive, but not many electrical options on these.

 

Here is a question, if you have 6 volt aftermarket turn signals added, is it just the flasher & indicator lights that need to be swapped? or does whole unit need to be swapped to 12 volt?

SNIPPED

I would just put an alternator on it and save yourself the grief, you're in it this far  

Starter doesn't know the difference and will last a long time

Just replace the flasher

   If the original radio works, don’t, under any circumstances, connect with a negative ground. If you do, it’ll instantly be junk, as it grounds thru its case. The only way to make it work is to completely isolate it from the rest of the vehicle (no simple project—that). Apparently, it was too much for the former owner of our car, since our is 6v neg ground, and the radio was/is a burnt hulk. I just stripped off the face-plate, put it in the dash, and the guts of the thing is sitting in a corner on the floor, patiently waiting for me to decide if I want to continue stripping it out, or just cut to the chase, and throw it in the trash . . . . As for the turn signal system, you’ll have to switch the flasher, and the bulbs, for 12v. In fact, you’ll have to switch all of the bulbs on the car, including the sealed beam headlites. They won’t last long at all having 12v coursing thru them.

I have three 1952 Imperials, all converted to 12V negative ground systems.  The 6V power window motors work fine (just don't stick your fingers in there when they're going up), and, as someone else already noted, the 6V starter will work fine too--just don't crank it for 2 or 3 minutes.  

I love 12V, although the purists turn up their noses.

Good luck!

many of the companies will not list their input power requirements to sustain the rated output voltage and amperage...for giggles if you search you will find that if you get a 10 amp continuous output at 12 volt from the typical 6 volt input inverter, you current input to produced that from the 6 volt source is approx. 23 amps...you just eat up 50% of your output from the generator at SPEED....if you run this inverter at idle with a generator given the output you are eating your battery reserve..this is a negative curve....be totally sure of the operating parameters of any inverter you should install.  At the cost of a quality inverter....practicality does not enter the equation in my opinion.

Why not install a 6 volt one wire alternator along with the inverter for the 12 volt needs ?  Do they produce 60 plus amps ?

you can...but now you got to make a real choice, do I stay with positive earth ground or go negative.   The cost of the alternator may not be an issue in means of ground preference and cost but the converter from the costs I have seen are quite chunk of change for one that can come close to handling any demand for modern conveniences and toys for the traveler and operate on positive ground circuits.  Maybe I have only been looking at the higher end of the retail business in both amperage supply and initial cost...but that is the real answer, a quality item that will handle my needs.
