Alternator Underdrive Pulley
Anyone ever had issues with their alternator pulleys being too big in diameter? If my engine is idling, the alternator will not charge the battery....If it's over say 2000 revs, it will charge. All of this being verified with a battery charger with an alternator checker on it.
It's a pain in the butt....especially recently...the car has been idling a lot while tuning on the carb....it hasn't been charging the battery enough...which didn't give my MSD enough juice to really give me a good spark....sooted the plugs up and it had a little miss to it....
I'm running March pulleys.....guess I'm gonna have to look for a smaller one....any ideas?
