The Electrical Panel - Tayana 37 Operation & Maintenance Manual

a. The Electrical Panel
The electrical distribution panel controls all of the 12 volt electrical
circuits in your yacht. You will note that it has both a battery condition
meter and an ammeter. The battery condition meter tells you the
measured state of the charge existing in your batteries; the ammeter tells
you how many amperes are being used at any instant of time. The
various circuits go through the circuit breakers on the board. These
circuit breakers act as both a switch and as an overload protection
device.
There is very little maintenance necessary on the panel. Open the door
and look at the back of the panel. You will see colored wires, which go
to the various electrical devices--the colors allow you to find the same
wires throughout the yacht. The panel should be kept dry at all costs. If a
circuit breaker trips and cuts the circuit, there is an overload condition.
This is usually because there is a short circuit. Always attempt to
discover what caused the circuit breaker to trip before depending on that
circuit again.
