- 2. A formal document that outlines the details of a repair or maintenance job to be performed on a vehicle.
- 5. The type of gas most commonly associated with lead-acid batteries used in vehicles.
- 8. The continuous electrical current flowing from the battery when the vehicle is turned off.
- 9. A tool used for measuring voltage, current, and resistance in automotive circuits
- 13. The equation: voltage = amps x ohms
- 16. A device that opens or closes an electrical circuit, allowing or stopping the flow of current to a component.
- 19. The amount of electrical current flowing through a circuit, measured in amperes (amps).

Down
- 1. The process and material used to join metal parts—typically wires or terminals—by melting a filler metal (solder) that bonds the connection when cooled
- 3. to ground Occurs when an unintended connection is made between a power wire and the vehicle’s ground (chassis or negative battery terminal).
- 4. Widely used in vehicles to manage high-current components without routing heavy wiring through the dashboard or control switches
- 6. A standardized interface used to connect diagnostic tools to a vehicle’s onboard computer system.
- 7. System that monitors and reports the performance of a vehicle’s engine, emissions, and other critical systems.
- 8. The vehicle’s main computer that manages both engine and transmission functions
- 9. The process of identifying and troubleshooting problems in a vehicle’s systems—mechanical, electrical, or electronic.
- 10. Refers to the electrical potential difference between two points in a circuit
- 11. A detailed diagram that shows the electrical connections and components within a circuit.
- 12. All the components that generate power and deliver it to the wheels to move the vehicle
- 14. refers to the return path for electrical current back to the battery’s negative terminal.
- 15. the process of testing and troubleshooting electrical circuits to identify faults or malfunctions
- 17. Codes are generated by the vehicle’s onboard diagnostic system (OBD or OBD-II) when it detects a malfunction.
- 18. The flow of electrical charge through a circuit, measured in amperes (amps). It’s one of the three key elements in Ohm’s Law
- 20. Refers to the opposition to the flow of electrical current in a circuit. It is measured in ohms
