So I installed a new alternator in my SPF over the weekend. Picked up a Powermaster which was basically identical to my previous as far as the hookup and wires are concerned. It is a 60/40 amp alternator. The "tag" read 71/45 (highway speed/idle).
My question is this: Is the alternator not powerful enough ?? At startup and idle the ammeter guage is jumping around a bit in the positive but will stop moving around if I give it a little gas and smooth the idle out. It reads in the positive which the last one did as well. But, at night when I turn the lights on they are quite dim but brighten up substantially when I rev the motor or start driving. Is this normal ?? Thanks in advance.

Also, when I first installed it and started the motor up, I touched the alternator with my bare hand and it gave me a little shock...I checked all the connections and the ground wire and everything was fine and when I touched it again there was no shock, everything seemed fine. Any thoughts ???
