What is a gfci oulet?
GFCI=Ground Fault Circuit InterrupterIt's an electronic circuit breaker that compares the current on two wires. If the current is NOT equal, the breaker trips and does so quickly enough to prevent electrocution in the event of a "ground fault".
What does p1747 fault code for Honda Civic relate to?
P1747 is the Transmission Electronic Pressure Control Solenoid Short Circuit. Can be in the wiring or internally.
What is the GFCI?
A "GFCI" is a ground fault circuit interrupter. For more information see the link below.
What is likely to happen if one rotating diode fills and become open circuit?
If this is a question about a flywheel diode, it is there to prevent excessive voltage buildup when an electronic swich is opened, so if it is not working (open circuit) there is a chance of a further fault developing in the circuit.

In relation to electric what does the term fault protection mean?
Protective devices - relays, CT,PT, isolators, circuit breakers are used for fault protection. Fault protection means If there is a fault in the circuit, the circuit must be cut off before any damage occurs due to fault.
Why you use relays in your circuit?
for switching and protect the circuit in case of fault.
What do ground fault relays do?
Ground fault relays sense ground faults in the circuit and trigger a circuit breaker to trip off
What fuses and circuit breakers provide protection in the event of?
Short circuit fault.

What does fuel pump relay primary circuit fault mean?
There could be a short to ground circuit . The fuel pump control circuit may also be sticking open which would also cause this fault.
