Front

What is the function of a Starter Relay?

Back

A Starter Relay is an electromechanical switch that controls the power to the starter motor, allowing the engine to start when the ignition is turned on.

Front

What does 'Power Control' mean in the context of a Starter Relay?

Back

Power Control refers to a system where the relay is activated by a power signal, allowing current to flow to the starter motor.

Front

What is the significance of Term 14 in a relay circuit?

Back

Term 14 measures the source voltage when the rear compartment lid release switch is pressed, indicating the relay's operational status.

Front

What happens to the current in a series circuit?

Back

In a series circuit, the current remains constant throughout all components, meaning it does not split or change.

Front

What do pins 30 and 87a represent in a relay?

Back

Pins 30 and 87a correspond to the normally closed (n/c) contact side of the relay, allowing current to flow when the relay is not energized.

Front

What does the electronic schematic symbol for a battery look like?

Back

The battery symbol typically consists of one long line (positive terminal) and one short line (negative terminal), representing the two terminals of the battery.

Front

What is the difference between 'Power Control' and 'Ground Control' in relay systems?

Back

Power Control activates the relay using a power signal, while Ground Control activates it using a ground signal.

Front

What is the role of a relay in an electrical circuit?

Back

A relay acts as a switch that opens or closes circuits electronically or electromechanically, allowing control of high-power devices with low-power signals.

Front

What does 'n/c' stand for in relay terminology?

Back

'n/c' stands for 'normally closed', indicating that the circuit is closed (current flows) when the relay is not energized.

Front

How does a battery function in an electrical circuit?

Back

A battery provides a source of electrical energy by converting chemical energy into electrical energy, supplying current to the circuit.
