Ron is quite correct about the fusebox. I upped to an alternator due to low voltage from my system and very dim lights. I was fortunate enough to have engines that could accept the simple bolt-on solution, but in the end, I never really got good voltage from the setup until I rehabilitated my primary fusebox and used dialectric grease on all my (now tight) connectors.

While he certainly offers a high-quality fusebox upgrade, you can fix it yourself if you want to soder metal or pick up some pure copper rivets and clean everything very thoroughly.

I'll probably get a block from ron at some point, but my system works okay for the moment. I do still see a dim glow from my AMP light with my blower motor in use.
