Electrical Trouble

Abodyjoe dual field single field Alt? How do I know? It does look different. My first Alt had pos and neg this alt has pos neg and then it's own ground. Did I get the wrong one. Does anyone know if I have to run a solid state voltage regulator with the ignitor system? I had a solid state and burned it up or it wasn't charging and car went dead at the nats. I put stock one in and system was charging?
