I have a 1984 Hunter 34. I recently discovered that the battery charger is wired into the starboard electrical outlets. In other words, I have to turn on the starboard outlets (when plugged into shore power) to charge the batteries. This, of course is separate from the alternator that also charges the batteries. Is this standard or is this something the previous owners rigged up? The power panel is not labeled in any way to suggest that the starboard outlet switch is also the battery charger. All you H34 peeps give me a shout!
