[razz9818]

ok so i got a 150amp alt and i think 70watts. question is why do my lights dim under 1rpm i get less power and obove its really bright. can i fix that so it stayes the same kinda worried (i dont know much about the alt since my friend picked it up for me)i have had it for a couple years now and never had a problem w/it but its starting to get on my nerves ....thanks in advance for ur input

because HO (high output) alternators are not actually designed for what we use them for. Most of them actually put out LESS amps than the factory alt at idle
