What's the deal with pulleys??

Is this not correct??

No because like i said the output of any alternator varies greatly depending on rpm. for honda's the charge is perfect at 2.5k-3k rpm this is hardly the average driving rpm of a civic owner. this means that if it's spinning slower then the new perfect charge is at say... 3.5k-4k. that's no big deal for a car with a 7k rpm rev limit. so No this will not affect your spark at all. beyond that your spark plugs will take as much spark as your Bat. will supply not your alternator. and as far as the electrical system that's what voltage regulators are for. (in case you didn't know you have one and it's purpose is to prevent running too high or too low a voltage to the electrical system. regardless of the output of the alternator)
