  Have stock 6 volt 36 Ford Fordor. What is advantage & possible disadvantages of having generator converted to alternator? Thanks.

  There are several differences between alternators and generators but I think the biggest is that with a generator, as you slow down or are driving in a slow parade the generator also slows down. Ever notice at night when you are parked with all the lights on the voltmeter shows little or even minus charge. The alternator keeps charging at the same rate, keeping the battery at peak charge. Modern cars with all the energy consuming options couldn't use a generator. Certified Auto Electric makes a conversion kit, 888-597-8278.

  I installed a six volt alternator in my '47 years ago when the generator quit. It is a "one wire" type. The first thing I noticed was that it didn't come on until the engine was revved very high. We made a new, smaller, pulley and it helped some, but required a very tight belt, not good for the water pumps. If I were to install another, I would use a two wire type that is turned on thru the ignition circuit, instead of relying on residual magnetism in the rotor.

  IMHO if you don't intend to do most of your driving at night or adding a 1,000 watt stereo system, stay with the generator.

Keeping a car as designed makes it easier to solve any problems that arise. Unless you have a lot of experience in diagnosing problems, like Supereal, you can end up with more problems than you had.

If you have a stock 6 volt car, there is no need to install an alternator. You can install a replacement for your cutout that is a voltage regulator and that will keep your battery charged.

Another disadvantage of the alternator, is that if a diode shorts out, it will drain your battery.
