When my stock 110 amp alternator went I replaced it with a 180 amp alternator thinking it would charge the 2 6 v GC batteries faster. 6 hrs of driving home did not recharge my batteries from 50% soc, It took my 40 amp B&B to complete the charge overnight. So I think there is more than just adding a bigger alternator that I don't completely understand. I read her that wire size and external rectifiers,and cooling are important. From what Phil posted 3-5 hrs of driving recharges his batteries. Have you guys added anything besides a larger alternator to charge your batteries faster?
