[QUOTE="wake894, post: 8211031, member: 659216"] i bought a db electrical 220a HO alternator for my 01 mustang and the regulator was bad sending 16volts to everything so i sent it back in and got it back with a new one but the voltage drops to 12.6 at idle and goes up to 14.4v at 1200 rpm. i emailed db about it and they said to use a one size smaller belt on it and it should work fine. i bought a 1/2inch smaller belt and it still does the same thing. i have the big 3 done in 1/0 wire and fused with 225a. i was wondering if anybody could give me advice on it before i send it back in again.
