I have a couple of extra alternators for my 2000 GL1500 and am planning on building a setup where I can, after hooking up to a 12 volt battery, get them turning at various RPMs. My question is, while viewing the alternator from the front (motor side), does it turn clockwise or counterclockwise? Also, since it has no pulley, has anyone come up with a temporary but sturdy hookup to attach the alternator to the power source, i.e. electric drill, 110 volt motor, etc.? My main objective is to check the voltage output at various RPMs before I install them, as well as to see if they need an overhaul before use. Any advise is definitely appreciated, 'cause at age 72, I really don't know everything there is to know, like I thought I did at age 16!!!
