Hunter e36 • DC ElectricEach battery bank is wired to a battery selector switchlocated under the chart table. A circuit breaker “DC Main”on the battery switch panel connects the batteries to theelectrical system. The batteries supply power, first tothe battery selector switch then to the 12 Volt DC Panelwhich distributes power to such equipment as cabinlights, instruments, and accessories.The negative terminal of all banks are attached to the DCGround connection on the engine. This system, known asthe negative ground system, is the approved system formarine DC electrical systems. The battery wiring systemhas two color coded wires. The yellow wire is the ground(negative), and the red wire is (positive).To avoid explosions, do not use jumper cables and abooster battery to start the engine. If batteries are dead,then remove and recharge them ashore.Batteries produce hydrogen and oxygen gasses whenthey are being charged. These explosive gasses escapethrough the vent/fill caps and may form an explosiveatmosphere around the battery if ventilation is poor. Thisgas may remain around the battery for several hours aftercharging. Sparks or flame can ignite the gas and causean explosion.2. Attach the negative cable to the negative (-) terminalon the battery.Note: Batteries should always be removed and installed bytrained, qualified persons to avoid all damages.Table 1 Recommended Batteries(or equivalent)MFG/PN Group Sise Volts QtyExidePrevailerPV-4D7.2.2 Battery Switch Panel4D 12 2The battery banks are connected to a battery selectorswitch (Fig. 7.1 shown without optional inverter) locatedunder the chart table.The selector switches are marked as to which batterythey control. Turning the selector switch to the Off positionturns power off to the respective circuits, likewise, theOn position turns power on.The following precautions must be taken:• The wiring to the batteries must have proper overcurrent protection in the form of fuse or breakers.• Use only battery chargers that have been listed by atesting agency, such as Underwriters Laboratories,Inc.• Follow the wiring diagrams exactly.To remove the battery:1. Turn off all power drawing breakers and isolate battery.2. Remove negative (-) cable first, then the positive (+).When you install a battery, the battery connections mustbe made properly.1. Attach the positive cable to the positive (+) terminalon the battery.Figure 7.1The battery switch panel houses the breakers for someof the main components in your DC system. The breakercontrols are marked at the switch panel, and control systemsor components on your boat that require a connectionthat remains energized even through the Main Panelmay be de-energized.The breakers and switches are described in greater detailin the “Breakers and Switches” section of this chapter.7.3
