Topic: 6 volt generator in a 12 volt system


52 Ford    -- 09-14-2020 @ 12:16 PM
  I plan on using my rebuilt 6 volt generator in a 12 volt system on my 52 Ford F1.
I know i need to change over to a 12 volt regulator and coil, but do I need to change over the starter solenoid, horn relay and headlight switch as well?
And if so should I be looking at the parts store for something like 1960 F100 Solenoid,headlight switch, horn relay ,coil and regulator?

  I have a ‘51 F1 that I converted to 12 volts because I often rent trailers and can’t be bothered with changing the trailer light bulbs.
I am using the 6 volt generator and am not happy with the charging rate..
I have a new regulator but it just does not put out enough voltage for driving around in heavy city traffic at night.
The light switch will be just fine, so will the starter relay (solenoid) for a while.
You may burn out the solenoid in a a year or two.
I’m thinking there is no horn relay.
Don’t forget the voltage resister for the instruments.

  For me this is one of those what if you could simply up voltage the output of the 6 volt generator which I assume you want to keep because of it's dimensions and mounting and the belt pulley sheave. The usual way to do this in a AC circuit would be to insert a transformer with the ratio of primary to secondary windings of 1:2. In 6: 12 out, the 6 volt wires are already oversize since they sized for a 6 volt system carry twice the amperes that the 12 out will carry. How could you get 6VDC to 6VAC? You need an inverter. These are quite common in solid state form today to go from 12VDC to 110VAC for marine or RV use. In your radio there is a simple vibrator and a diode tube and voltage regulator tube to provide power to 300VAC amplifier tubes. Hmmm! Solar cells are only about .5 volt DC output so at one time I tried to hook a bunch of them up in series , like about 28 of them and then hook up a solid state flip flop to make 14VAC as an alternator might make. As you can see I'm not much of a teacher. Not even an electrician but I can describe how to get from 1932 to 1978 in electrical terminology skipping the 12VAC alternator Chrysler put on their cars in 1960. Did the 1965 Mustang I rented have an alternator? I don't know. Fortunately it was much more reliable than ... but that gets us to permanent magnet 12VDC starters. Notice 12VAC Alternator and 12VDC starter. There must be some magic in there in between. Hmmm, the voltage regulator on the Chrysler product has solid state diodes on top as flat disks, not the big glass envelope tube diodes of the radios before. Note, I did not change the radio power supply from tubes to some sort of AC solid state form. In 1965, transistors were low power and the quality did not approach vacuum tube. It's 2020 now and I once had a 10 amp FET and did not need a Darlington to handle that kind of amperage or power. I mean 9 volts like a transistor radio times 10 amps is 90 watts! Imagine the boom box I could build! For a time 24 and even 40 volt power steering systems were being proposed for near term use on cars. No more leaky hydraulics. Infinite ratio beyond full time power steering. To be continued. Bear with me or grab what I pointed to on the shelf. I'm sure it's there now.
