    I have a question that I have not been successful at finding an answer to. I have a '51 International L-110 that runs on a 6 volt system. I am fine with some of the components being 6 volt, but I want to run some add-on accessories that are 12 volt. I am not really interested in converting to 12 volt all-around, but wanted to either add a second 6 volt battery with a series parallel switch, or add a 12 volt battery completely separate from everything, with the exception of charging it. I would imagine that adding the 12 volt battery and having the separate electrical system might be easiest if I can find a way to charge it off the 6 volt system. Can anyone shed some light on how I might be able to accomplish this goal?

    You might try the accesories on the 6V. I ran a 12 electric fuel pump for years on 6V.

    I never thought to do something like that! Thank you for replying.

    PS. Would you think it makes any difference when the system is positive ground? I would imagine it wouldn't make a difference as long as I keep with the positive line on the inverter going to the frame. I just have not dealt with the reversed battery like this before. Thanks!
     
  5. If the frame of the inverter is grounded, you would have to mount in on an insulated panel, then take your outputs from the case (neg) and run the positive wire to the vehicle ground.

    That is an excellent point. Thank you!
     
  7. They actually come both ways.

    Run 2 6v batteries if you have room. Ground battery ''A'' neg., + to neg post on battery ''B'', 12v gen & reg, no s/p **** ... run the 6v stuff from the + post of battery "A", everything else from 12v of both. Your binder will need to have the 6v gauge terminals reversed for neg. grd.
    Starter is fine as is, gas gauge can be a ***** on some vehicles ....
    Inverters are seldom a long lasting solution.
