Farm equipment and industrial applications. That is about all they are good for IMHO.

I'n not sure what they came on, in fact I have never seen one factory installed in a car. But just about any delco alternator from the 70's and 80's and into the 90's can be converted into a single post alternator. It requires a module that has a zenner diode in it. It will charge your battery but not discharge the battery when the engine is shut off. Just about any automotive alternator/electric shop can convert the delco of these years into a single post alternator. The dependability depends on the quality of the module installed. The draw back is that you wont be able to use your stock gauge or idiot light. But they work great and I have put them on a lot of vehicles. Expect to pay around 65.00$ You can buy the module and convert it youself.

This fellow does it with a regulator that does not turn on until the alternator is turning 3,000 RPM (2,200 RPM engine speed - due to smaller pulley on alternator) it requires a jumper. If you use an amp-meter in the circuit and the amp-meter decides to quit working your alternator will not charge the system.

I like them better when the moduel is changed to the type that I have refered to. These type alternators are great on rat rods and I use them all the time on older cars and old VW Beetles. I have put them on old British sport cars also. However I would not use one of these in a late model stock replacement.
