Tim: The reason I am up[grading is I found out the one in the boat is not Marine. PLus I dont know how many amps it is putting out, and also, When I am idleing, my gauge drops down. It is not an accurate reading, but it drops a few volts from where it normally is.
I plan on putting a volt meter to it this weekend. Is there a way to tell how many amps the alternator is pushing wihtout taking it out of the boat?
ANother question is if I get the 100 amp alterantor will I have to change my wiring from the alternator? I have a 93 mastercraft prostar 205.
