Wiring for an alternator

I changed my dyno for a alternator some time ago and found on the net that I should wore the lives from the old dyno in line with the batterie live but I did also have a problem with the head light switch at the time and don't know if it will happen again with a new switch if that makes sense.
I don't want to blow a new switch maybe because I've done something wrong at the alternator !
Any info on the wiring would be great thanks ash
