(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.

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