Sorry Beta are talking rubbish just do the maths. 100 amp alternator at 24v will give 2.4kw 1 kw = 1.3hp 2.4kw = 3.2hp so unless you have a 10hp engine they are telling porkies. If you have a 40hp engine you would need somewhere in the region of a 500amp alternator to take one third of the engine power! don't you just love it when people believe what a salesman tells them ;-0 Julian
