Should be fairly easy,both should have three wires of the same colour coming out,that are the ones that carry the current but i am know expert.

I used a small one off of a Jap car, cant remember wich nissan I think, it had a built in reg/rec so output current was already regulated, made a real easy job of the wiring.

is good for the soul(not to mention the bank balance :D ).

Use a car alternator when the original blows up. Power take off from points or electronic pickup point simply bolt on pulley using a longer bolt. I mounted the alternator between the down pipes and the frame only ensure the shafts line up. Gearing - I find a 1 to 1 ratio OK. Use standard pulley on the alternator and similar from one liberated from another alternator on the power take off. The belt type and size was worked out at my local industrial Belt, Pulley and Bearing suppliers for a whopping £1.45. Don't try a chain drive they sound and look mental, mine lasted 450 - 500 miles and then broke and flew off at 80+. Cost £15 - 20. I now have 55 Amps charging power and 130 Watt lamp and spots! see picture [Mouse <mouse@ratbike.org>]


Some bikes used a piggy back alternator that was belt driven these are much smaller than car ones(cbx 750?)

Car alternators are of course cheap,big and easy to wire up.Depends which one u use.Most have reg/rect in em which is a bonus on your GS. :)
