adding an alternator to a clone

[sho305]

One thing to note is your loss will also be connected to the rpm you run it at. If you put a smaller pulley on the engine loss will be less. Figure you will be running minimum 2,000rpm while the cart is moving where you may need 10amps of power to run 55w driving lights, so really you can size the pulley to deliver higher output at 3500rpm when you had it on the floor as you really don't need that much power in a cart....unless you run a big amplified stereo or lots of lights/etc. In that case you want some power at idle speeds, but a normal cart can reduce alt rpm and save engine power. There is no doubt my 55w lights get brighter at about 2K rpm and greater with the stock generator and that works fine (15A max output on those, so you could run a gen quite slow and have that though it may not be good for it. It could lose cooling from its fan at constant really low rpm).
