Hi folks, our 1990 express cruiser has the 2 454's. I'm installing a new battery isolator, on the package it states "this isolator will not with self-exciting alternators. My question is, do i have self-exciting alternators on our boat?? I put new alternators on 2 years ago. I have pics of the old and new. From looking around, it appears most self exciting alternators have a rectangular socket for a plug with a couple wires to go into. These do not. Im pretty sure the terminal that says "ac tap" was never used. Hopefully someone out there is more alternator savy than I and can put some wind in my sails. Thanks in advance gents. Ron
