1991 Dodge w250 cummins turbo diesel

I've got a 1990 1/2 1st gen Cummins, my battery was over charging so I swapped it to a single wire regulator but I'm still having over charging problems ideas?

Our trucks are famous for bad grounds. Both my D250s had a dedicated ground wire run from the reg's mounting screw to neg battery post. But ya, some of these regulators last years, and others maybe only a few months.
