Ummm... mechanical loses from studies actually show mechanical loads only making up about 5 to 10% of the total load an alternator places on the engine.
I don't buy disconnecting the belt from the alternator getting someone %5 more mileage over a kill switch. The facts just don't support it.
Once again this is a thread on alternator modification and not an alternator disconnect, kill switch, or solar augmentation. There are other threads on ecomodder for that.
