Let me play Devil's advocate.....
Get your battery checked. Otherwise with no shorts, good battery and alternator/regulator etc..... Why would you need a higher output alternator, unless you're really pulling a lot of juice to operate additional equipment? It's working fine, except at idle, correct? Your problem seems to be at the low end of the RPM range, (dimming lights). An alternator has to get up to a certain speed to maintain a given charge to overcome the load, doesn't it? The original pulley size is designed to give you that alternator speed at idle. Once you change the pulleys, you've automatically reduced the low end (idle) charge rate. A higher amp battery may help with the head light situation for a while, but at extended idle, the same dimming will occur, won't it?
