ABYC Electrical Wiring - DC Circuits
Wire Color Code Exam Questions &
Answers (Grade A+)
What type(s) of circuits is this wire installed in? (i.e., YELLOW with a
RED Stripe Wire)?
What components would it connect together? -
correct answer ✅ENGINE STARTING CIRCUIT
CONNECTIONS - located between the Key Switch or Starter Button
on electric start motors and the engine-mounted Starter Solenoid
on the outboard or inboard engine's starter assembly. The wire will
usually pass through a neutral safety switch located in the remote
control shifter mechanism of a boat as well.
What types of circuit(s) is this wire installed in? (i.e., LIGHT BLUE
Wire) What components would it connect together? -
correct answer ✅OIL PRESSURE SENSOR CIRCUIT(S)
CONNECTIONS - located between the engine's Oil Pressure Sensor
and the Oil Pressure Gauge on the cockpit Instrument Panel.
What types of circuit(s) is this wire installed in? (i.e., PINK Wire)
What components would it connect together? -
correct answer ✅FUEL LEVEL CIRCUITS

Answers (Grade A+)
CONNECTIONS - located between the Fuel Tank Sender on top of
the fuel tank and the Fuel Gauge on the Instrument Panel
What types of circuit(s) is this wire installed in? (i.e., GREEN with a
YELLOW Stripe Wire) Where would you install it or expect to see it
installed on a boat? -
correct answer ✅DC GROUNDING CONDUCTOR
CONNECTIONS:
1. In electrical inter-connections between all metallic items that are
connected to the boat's hull or through-hull fittings and the lighting
arrestor mounted on the top deck of a boat.
2. On any intra-engine or intra-transmission bonding wires that are
located below the deck in a boat and must have insulated wire to
prevent arcing and sparking that could cause vapors to ignite or
explode.
What types of circuit(s) is this wire installed in? (i.e., BROWN or
DARK BROWN Wire) What components would it connect together?
-
correct answer ✅GENERATOR ARMATURES, ALTERNATOR CHARGE
