20-22 Gauge Wire - Answers Used in radio speaker wires
Battery Cables - Answers Largest wires used in the automotive electrical system
Color of Plastic of Blade Fuses - Answers indicates the maximum current flow
Spark Plug Circuit - Answers Least likely to be controlled by mega fuses
Circuit Breakers - Answers used to prevent harmful overload in a circuit by opening the circuit and
stopping the current flow to prevent overheating and possibly fire caused by hot wires or electrical
components
Cycling-Type Circuit Breakers - Answers reset when the current stops flowing, thus causing the bimetallic
strip to cool and the circuit to close again.
Power Steering Systems - Answers least likely to have circuit breakers in the circuits
Solder will not adhere to Aluminum - Answers the heat causes an oxide coating on the surface of the
aluminum
Petroleum Jelly - Answers used to coat a splice, crimped connection to prevent corrosion
Orange Conduit - Answers used to cover wiring that carries high-voltage current from 144 to 650 volts
American Wire Gauge System Characteristic - Answers the greater the amount of current that is flowing
through a wire, the larger the diameter that will be required.
Orange Conduit Circuit - Answers most likely found in hybrid electric vehicles
Methods to Check Fusible Links & Mega Fuses truth - Answers if the insulation of the fusible link
stretches, then the wire inside has melted and the fusible link must be replaced
Primary Wires - Answers are designed to operate at or near battery voltage
Metric Gauge Size & AWG size - Answers Metric wire size increases with increase in the area AND AWG
size gets smaller with larger size wire.
Circuit Breakers Views - Answers protects the circuit from overheating AND provides sufficient current
flow to maintain at least partial headlight operation
PTC Circuit Protector Truth - Answers the high resistance of the PTC reduces current flow in the circuit
Mini Fuses - Answers Make troubleshooting easier because each circuit is separate
Blue or Yellow Conduits - Answers used for electric power steering
, Maxi Fuses - Answers used to replace fusible links in many vehicles
Higher AWG number - Answers the smaller the wire diameter
Metric Wire Size - Answers measured in units of square millimeters
Fuse Rating - Answers should be higher than the normal current for the circuit AND of the fuse rating,
80% should equal the current in the circuit
Connector - Answers usually a plastic piece where terminals lock in
Rosin Core - Answers solder that should be used for electrical work
Performing Wire Repair Under Hood - Answers use a solder & adhesive-lined heat shrink tubing or a
crimp-&-seal connector
Testing Fuses - Answers a test light should light on both test points of the fuse if it is ok AND the fuse is
defective if a test light only lights on one side of the fuse
Plastic Conduit Covering - Answers used to identify the temp rating of the conduit, color identifies the
voltage level of conduits being protected, AND protects the wiring.
Insulated & Braided Ground Straps - Answers more flexible to allow movement of the engine w/o
breaking the wire
Increase in current flow - Answers causes a fuse to blow
Automotive Wiring - Answers Made from strands of copper covered by plastic insulation.
Copper - Answers great conductor, is reasonably priced, and very flexible.
Solid Copper Wire - Answers Will break. Used for starter armature & alternator stator windings.
American Wire Gauge (AWG) - Answers Wiring is sized & purchased according to gauge size assigned by
the AWG system.
AWG Gauge Numbers Vs. Gauge Sizes - Answers Gauge numbers increases, the size of the conductor
wire decreases. Greater the amount of current that is flowing through a wire, the larger the diameter
that will be required.
Wire Diameter - Answers Diameter of metal conductor without insulator.
20 to 22 Gauge - Answers Used for radio speaker wires
18 Gauge - Answers Used for small bulbs & short leads
16 Gauge - Answers used for taillights, gas gauge, turn signals, and windshield wipers
