Battery
This is the main function of a car battery.
What is to store and supply electrical energy.
This component engages the engine to start it.
What is the starter motor.
This drives the alternator.
What is the drive belt, v belt, or serpentine belt.
A vehicle's left tail light works but the right does not. This is the MOST likely cause.
What is a burnt bulb.
This informs the driver of the vehicle's speed.
What is the speedometer.
The hydrometer reading is 1.265 in each battery cell. What does this indicate?
What is a fully charged, healthy battery.
This part sends signal to the starter solenoid when the key is turned to "start" position.
What is the ignition switch.
This is the minimum voltage for a battery to test "good" on a VAT-40 charging system test.
What is 10.5v.
This electric device is used to control current flow to the dome lights.
What is a rheostat.
This network connects multiple electronic modules in a vehicle.
What is the CAN bus.
Low battery voltage can cause this problem when starting.
What is slow or no engine cranking.
This component allows high current flow to the starter when engaged.
What is the starter solenoid.
This could cause the drive belt to squeal under high alternator load.
What is a faulty tensioner or worn belt.
This type of light provides better efficiency and longer service life.
What is LED.
This display gives real-time data such as fuel economy and warnings.
What is the driver information system or digital instrument cluster.
This is the minimum voltage for a battery to test "good" on a VAT-40 load test.
What is 9.6v.
A rapid clicking noise when trying to start often indicates this issue.
What is a weak battery, bad connection, or unplanned resistance.
It's what changes AC current to DC in an alternator.
What is a rectifier bridge or diode.
Flickering headlights often indicate a problem with this.
What is the alternator or poor ground.
This can cause TPMS light to be illuminated upon a cold start.
What is cold temperature/weather.
This is how to find the amperage for a VAT 40 load test.
What is halve the CCA rating.
This sensor must complete the circuit for ignition to send a signal to the starter.
What is the neutral safety switch.
This component rotates, causing a magnetic field.
What is the rotor.
What is the automatic headlight leveling/aiming.
Anti-theft systems often require this component in order to start the vehicle.
What is a transponder.
