I can't find an external port for a fuse or reset button...  Is it dead or is there something I may be able to do to fix it???  It's only a couple years old but it came with the boat when I bought it so I don't know if the warranty was transferable.  

If it's fused, it would be in between the charger and the + lead that goes to the battery.

I wouldn't mention second ownership.  I'd call BPS tell them the problem and see what they have to say.  Here at the main store in Spfld MO they exchanged a fly rod once that had been in a house fire.  You never know unless you ask.
