When I bought it new it was rated at 200. I took it to Autozone to test it but they couldn't measure the output. When I replaced a factory alt with this one the volt meter was about 1+ volts higher at WOT. I was getting 12 volts at best at WOT with the factory alt. With this one I was getting 13 plus.
The only reason I am selling this is was I had it as a spare. I have since bought chrome Alternator.
