Guest presasa Posted April 22, 2011 Share Posted April 22, 2011 greetings all - new to this forumI own a 55 DeSoto and I am in the process of converting the electrical system to a 12v system. The power steering pump is piggy-back to the generator, my thought was leaving the generator and installing a 12V generator voltage regulator, I think this will work. I would appreciate your commentsAP Link to comment Share on other sites More sharing options...
Rusty_OToole Posted April 22, 2011 Share Posted April 22, 2011 1st I have changed 6 volt cars to 12 volts but would not do it again. It is not worth the bother. So much easier just to fix the 6 volt system. You may not see this now, but you will before you get done. Your car is one of the hardest to change to 12 volts and you are only beginning.2nd your generator will not work, not even with a new regulator. You will have to either buy a new 12v generator or else add an alternator someplace else and then, either jimmy up a new power steering pump or else take the brushes out of the old gen and let it freewheel.Once you get the generator problem solved you have barely begun. Good luck. Link to comment Share on other sites More sharing options...

Joseph P. Indusi Posted April 22, 2011 Share Posted April 22, 2011 I must agree with Rusty. When these cars were used daily, back in the day, they were relaible. Better to retain the 6 volt system and get it into top shape. The conversion opens up a whole can of worms.Joe Link to comment Share on other sites More sharing options...
Rusty_OToole Posted April 22, 2011 Share Posted April 22, 2011 Just putting everything in good shape and buying an Optima battery should be all you need to do. Optima batteries are better than anything available in the 50s and help make up for the shortcomings of the 6 volt system/ Link to comment Share on other sites More sharing options...
Guest De Soto Frank Posted April 22, 2011 Share Posted April 22, 2011 Drove my '55 Fireflite for years on six-volts back in the 1980's - never any electrical problems.If you're dead-set on the change-over, a generator from a '56 De Soto or Chrysler equipped with power-steering would do the trick. MoPars went 12-volts in '56, and the '55 & '56 are almost identical mechanically. Link to comment Share on other sites More sharing options...
Rogilio Posted September 18, 2019 Share Posted September 18, 2019 External Hand Brake lining for ‘55 Fireflite Anyone rebuilt / replaced their HB lining? Looks like you need to fabricate the lining yourself and rivet the new material to the outer band assembly. Where does one find the lining material? Are there kits available anywhere?
