What's the fault code number? The only time I've ever seen the term "smart alternator fault" was on a Ford. The reason I asked about the fault code number is that most tuners show code P1632 as the fault you mentioned but that's wrong because the 'smart alternator' thing is a Ford thing. If that's the code you're getting, the code number is proper, P1632, but in GM codes it's a theft system-fuel cutoff fault. Unfortunately, I've never experienced it and don't know how to fix it.
