(Print) Use this randomly generated list as your call list when playing the game. There is no need to say the BINGO column name. Place some kind of mark (like an X, a checkmark, a dot, tally mark, etc) on each cell as you announce it, to keep track. You can also cut out each item, place them in a bag and pull words from the bag.

Stores electrical charge and releases it when needed.
capacitor
Common return path for electrical current; typically connected to the vehicle chassis.
ground
Connection point for wiring or components.
terminal
Opposition to current flow, measured in ohms (Ω)
resistance (R)
Diagnostic code stored by the vehicle’s control module when a fault occurs.
trouble code (DTC)
A complete path with no open circuits; verified with a meter.
continuity
Components connected end-to-end; same current flows through all.
series circuit
Controls alternator output voltage.
regulator
A complete path for current to flow.
circuit
Protective device that melts to open the circuit when current is too high.
fuse
Manually operated device that opens or closes a circuit.
switch
the stationary coil of wire inside the alternator
stator
Converts AC current to DC current inside the alternator.
rectifier diode
a metal fastener used to secure other fasteners, such as nuts or bolts, and prevent them from loosening due to vibration.
cotter pin
a type of non-volatile memory used in control modules (ECUs/ECMs) to store data even when the vehicle’s battery is disconnected.
EEPROM
Unit of electrical power; Power = Voltage × Current.
watt (W)
The flow of electrons through a conductor, measured in amperes (amps).
current (I)
Electrically operated switch used to control high-current circuits with low current.
relay
Bundle of electrical wires in protective covering.
harness
Components connected across the same voltage; current divides among branches.
parallel circuit
Unit used to measure electrical current flow.
ampere (Amp)
A break or interruption in the circuit preventing current flow.
open circuit
Check to see if a circuit path is complete.
continuity test
Electrical pressure or potential difference that pushes current through a circuit.
voltage (V)
Generates electrical current while the engine runs; charges the battery.
alternator
a reversing switch that keeps the motor turning smoothly by flipping the current direction at just the right time.
commutator
Any component that uses electrical energy (bulb, motor, heater, etc.).
load
Component that limits or controls current flow.
resistor
Electromagnetic switch that moves a plunger or contacts (used in starters).
solenoid
Unwanted electrical drain from the battery when the vehicle is off.
parasitic draw
Stores electrical energy in chemical form; provides voltage to the system.
battery
an electronic testing instrument that graphically displays electrical signals as a waveform on a screen, showing how voltage changes over time.
oscilloscope
Unintended path of low resistance causing excessive current flow.
short circuit
Stable voltage (usually 5V) supplied by an ECU to a sensor.
reference voltage
Tool used to measure voltage, resistance, and current.
Multimeter (DVOM)
The relationship between voltage, current, and resistance: V = I × R
Ohm’s Law
Device that joins electrical wires or components together.
connector
