"Need help to upgrade original alternators to more powerful one's, also will like to add another battery for house, separated from the starting batt. Can I use single wire alt? What kind of diode boxes are the best?
New to Chris-Craft. Twin 454"

".."Can I use single wire alt?"

Yes, but understand up front that they don't operate until you 'boot' the throttle at start up, and they sometimes stop charging at low idle speed.

"What kind of diode boxes are the best?"

NONE! I use the standad Perko switch to hook all 5 of my batteries togteher. None of that electronic junk for me. It's been working perfectly without it for years. (In other words, why go with expensive electronic battery black boxes that could fail on you?)

"Check out the Balmar Line of alternators, they have drop on models to fit most vessels, along with everything you need to do the job."
