Rick, Our M-15 #407 came new with the electrical package. The battery is a group 24 and is mounted in a battery box directly below the opening hatch under the V-berth. Our below V-berth cavity still has the Styrofoam floatation, the battery box is surrounded by the Styrofoam and is literally directly below the wood access cover. The electrical panel contains several switches mounted vertically in a row (5 switches I believe) and is mounted on the flat vertical surface of the exterior of the port interior locker. If you were sitting on the porta-potty, you could kick the switch panel with your right foot. The switches have teak trim and a piece of Plexiglas that slides down in front of them to protect them. Not all the switches are used, and several are labeled with white on black engraved labels. The wiring from the battery to the switch panel runs from under the V-berth, through a hole drilled into the port interior locker, to the switch panel. The wiring from the switch panel to the mast head lights runs up the interior port-side - angles across near the port window - then across the cabin top over to under the mast tabernacle - exits the interior just in front of the mast. The wires are held in place with a series of plastic wire/cable clamps, secured to the bottom side of deck hardware. We added spiral wrapping around the wires to keep them bundled nicely. A picture would be worth a thousand words. Our digital camera will be home later this week and I could send pictures if they would help. On our M-15 there are no interior lights. The only thing powered by the battery is our mast head Navigational lights, the internal compass light, and we added a VHF radio. We also added a cigarette lighter type plug for other accessories.

First, can someone tell me the stock layout of the components in an M15, i.e.. battery, switch panel, wire buss? Also, any interior lights, electronics or other components would be helpful. Second, is it possible to put to much weight forward in an M15? The smallest marine deep cycle battery (80 amps) seems to weigh about 50 pounds. I was thinking of putting the battery in the foremost locker just forward of the ballast bulge. I was planning on keeping my second anchor, chain and rode, 30-40 pounds, in that locker also. Maybe the answer to my first question will solve this issue. Thanks, Rick Langer M15 #337 _______________________________________________ http://mailman.xmission.com/cgi-bin/mailman/listinfo/montgomery_boats
