Another thing i want to add after a friend called me asking about a belt being thrown after hes on the hamma. This is most likely an alternator locking up. All his alts are externally regulated. Now we just have to find the bad one. When an alt locks up under load it could be a couple of things. Internally regulated alts that lock usually means the regulator is spent. But for those that have no internal regulation, its either a bad stator or rectifier (if there is an internal rect). An amp clamp is a good investment if u plan on doing competition setups or run multiple alts.
