I thought the discussion had veered to a 'does Headlights On waste petrol' discussion... or at least this part of it. paulh

Does that work for the air-conditioner as well? Exactly the same if the air conditioner is an alternator. I know stuff all about electrics, which is probably obvious.. but if the moving parts of the alternator are in constant motion which is determined by the crankshaft, and is producing a supply of electricity, and the current produced is drawn on my the engine electrics, other electrics, whatever is left is stored in the battery, and whatever is left over after that disappears into void, and the load on the crank of the moving parts of the alternator is constant, how does adding more load to the alternator output increase the physical load on the crank and increase fuel consumption?

Now do you understand ( the alternator is not a constant load) |
