Electrical Symbols
Diode
The diode is a solid state device which passes electricity in one direction only. Electrons flow through the diode
against the direction of the arrow. Diodes typically use 0.7 volts to pass electricity.
Push Button Switch
When the button on the push button switch is pressed, the bar moves down to make a path for the electricity
between the two contacts.
Single Pole Double Throw Switch
The switch carries electricity from a single input to none, or one of two possible outputs.
Shorting Switch
The switch carries electricity from a single input to none, one, or both outputs.
Single Pole Triple Throw Switch
The switch carries electricity from a single output to one of three possible outputs. If two or more switches are
ganged, then they move together with each other.
Resistor
Passive device used to reduce the flow of electricity from one part of a circuit to another.
Coil
Many turns of wire which act as an electromagnet when electricity flows through the wire.
Fuse
A fuse is a fusible link of metal that is designed to melt if more than the rated amount of power is passed
through the device. The melting of the fuse will immediately stop the flow of electricity in a circuit. Fuses are
rated in “Amps”
Electrical Circuits
Lead acid batteries such as those found in motorcycles are designed for a charging voltage of 14.25 volts.
Batteries which are subjected to greater than 14.25 volts for extended periods of time can suffer permanent
damage due to the electrolyte boiling dry. Charging voltage of less than 14.25 volts will result in an inadequate
charge delivered to the battery.
Automotive batteries operate at 12 volts. This is not enough voltage to harm people in any way. However, the
battery stores a huge amount of electricity in the form of electrons. If the electrons are allowed to flow from the
battery without restriction, then the wires carrying the electricity will become hot enough to melt. The melting
wires are extremely dangerous and can easily burn you.
Most problems in automotive electrical circuits are caused by poor connections. Make sure that all connection
points are clean and tight.
If the flow of electricity through a wire is interrupted due to a break in the wire or a poor connection, then the
circuit is said to be “an open circuit”
The flow of electricity through a circuit always takes the path of least resistance. If there is an accidental path of
extremely low resistance created in a circuit, the circuit is said to have a “short circuit” A short circuit will
usually result in the melting of the fuse protecting that circuit.
