While preparing my '89 Catalina 22 for the season, I was not able to get any of the electrical systems to work. After some troubleshooting, I think that the fuse in the panel is defective. Catalina Direct has the original part (Catalina Direct: Circuit Breaker 30 AmpPush-On/Push-Off
), but it's pretty expensive. So, I'm going to replace it with a Blue Sea version (Circuit Breaker Push Button 30 Amp with Screw Terminals - PN 2136 - Blue Sea Systems
While I was doing research to see if I could make the part substitution, I read that new boats have overload protection within 7" of the battery. I'm happy to retrofit my boat to do the same, but I don't know exactly how to do that.
What kind of installation should I be looking at? Is there a simple inline fuse that I can put in place? And what size fuse should I use?
If I add the breaker there, do I still need to have the one in the panel or will that cover both needs?
