Installing The Electrical Systems (Module 2)

Module Two - Deliver power to controls

In the previous module we delivered 'domestic' power from the battery, in the aft starboard locker, to the electrics panel inside the console in the wheelhouse.

In this module we will take the power from the two terminals we fitted on the electrics panel (fig 1) to the switch units located in the front of the Console .

(fig 1)

(fig 2)

The switch panel comprises three switches, top left, and three circular fuses, centre top. Bottom right is a switch that allows the voltage in Battery 1 to be read in the square window display above it- when moved right - or the voltage to Battery 2 when moved to the left. Finally, at the bottom left  there is a circular 12V plug outlet.

 

The back of the panel (fig 3)shows a series of wires that need attaching to the two terminals (fig 1) we fitted 

(fig 3)

Obviously there are too many wires for only two terminals and so we need to extend range of the terminals by adding two busbars (fig 4): positive bar on right and negative on the left. The negative terminal being connected to the left bus, and positive terminal to the right bus

(fig 4)

Now wires from the switch panel can be attached to bus bars. Electricity will flow from the battery, along the cables to the two terminals, then into the bus bars and through the red wires to the switch panel (fig 5) and back to the battery along the black wires.
