1.Technician A says that wires and wiring harnesses are the arteries of the vehicle's electrical system, and as such they need to be kept in good condition, free of any damage or corrosion. Technician B says that they carry the electrical power and signals through the vehicle to control virtually all of the systems on a vehicle. Who is correct?

2.Technician A says the insulation is designed to protect the wire and prevent leakage of the current flow so that it can get to its intended destination. Technician B says aluminum is typically used because it offers low electrical resistance and remains flexible even after years of use. Who is correct?

3.Technician A says selecting a wire gauge that is too large increases the amount of current flowing into the wiring harnesses. Technician B says the resistance of a wire affects how much current it can carry. Who is correct?

4.Technician A says that terminals installed to wire ends provide low-current termination to wires. Technician B says that terminals allow voltage to be conducted from the end of one wire to the end of another wire. Who is correct?

5.Technician A says a common mistake while soldering is trying to apply the solder directly to the tip of the soldering iron while the iron is heating up the wires. Technician B says it will not melt the solder leading to a cold joint. Who is correct?

6.Technician A says linear diagrams are a variation of the map diagram. Technician B says symbols for components are always pictorial. Who is correct?

7.Technician A says DIN schematic diagrams are also called power source track wiring diagrams because they show the power source at the top of the page and the ground points at the bottom. Technician B says newer DIN standards do indicate on which side of the vehicle a component may be located. Who is correct?

8.Technician A says knowing the standards for wiring colors makes the job of reading and interpreting schematics easier. Technician B says some colors and terminal designations for wiring are used across a number of standards. Who is correct?

9.Technician A says DIN wiring diagrams also indicate the wire gauge used (shown in mm2), designating the cross sectional area of the wire. Technician B says because standards exist for the maximum permissible voltage drop across a circuit, wire gauge is critical. Who is correct?

10.Technician A says wiring diagrams tell the user where pin numbers for wires could terminate. Technician B says knowing where the wires terminate intensifies the diagnostic procedure. Who is correct?
