      Only when you absolutely need more power, and are over working your current one.




      Everyone here underestimates how much power it takes to turn one of those alternators. It takes a lot of horsepower to turn an alternator the size of a 140amp CS144, and is completely useless unless you're running an EXTREME amount of electronics.
