I have sold hundreds of these to the heavy trucking industry
They are manufactured by Motorola and are of very high quality.
A good percentage of heavy trucks today use these for 100s of thousands of miles.
If you belt to a 6 hp ChangFa or a Lister type engine you will have 80 amp contentious duty battery charger for a life time. Or they are perfect for off grid living using a battery bank and a inverter .
They are a 12 volt , 140amp and good to 4500rpm
My price is $260 plus shipping. These are first quality new in the box
they do not have pulleys but I am working on a source. Pulleys are common and obtainable at most truck supplies
