Exam 35: Electrical Wiring, Connector Terminal Repair

Which of the following is a means of 'protecting' a circuit so that it would be coded grey using SAE wiring protocols?

What is the reason for using gold and platinum coated terminals in connectors in chassis electronic wiring?

In chassis wiring that observes the new SAE wiring standards, what is indicated by a gray wire?

When required to make butt connections on multiple wires within a harness, what should be done to avoid a bulge at the connection junctions?

When a non-cycling circuit breaker trips open, specifically what prevents the armature from closing when it cools?

Before crimping a new terminal on a typical weatherproof connector assembly, which of the following should be done FIRST?

When considering at the codes used for standard SAE relay assignments, which of the codes below correctly correlate the old and new SAE assignments?

You are testing a running motor in a series circuit using a voltmeter and identify the following circuit conditions: Voltage measured from motor positive terminal to chassis ground: 8.6 V-DC Voltage measured from motor negative terminal to chassis ground: 0 V-DC Voltage dropped across motor positive and negative terminals: 8.6 volts Where is the problem in the circuit likely to be found?

Technician A says that in chassis wiring that observes the new SAE wiring standards, any white wire with an orange tracer indicates a protected circuit. Technician B says that over 100 different colors identify different wires used in the new SAE wiring standards. Who is correct?

Technician A says that in a truck using virtual circuit protection devices, the circuit is tripped open when logic analysis of the circuit conditions determines that it is overloaded. Technician B says that when a virtual fuse trips open, it must be replaced by another using the identical OEM part number. Who is correct?

When sealing a butt splice with heat shrink conduit, what should be used to heat the conduit?

What are the terminal contacts inserted to when assembling in a Deutsch type, barrel connector?

Technician A says that four-terminal relays are commonly used in truck wiring today. Technician B says that a four-terminal relay eliminates the normally-closed (NC) option used on a five-terminal relay. Who is correct?

Which of the following letter designations identifies SAE wiring sectors that handle the engine/fuel control and management circuits?

You are testing an energized solenoid in a series circuit using a voltmeter and identify the following circuit conditions: Voltage measured from solenoid positive terminal to chassis ground: 12.6 V-DC Voltage measured from solenoid negative terminal to chassis ground: 0.1 V-DC Voltage dropped across solenoid positive to negative terminals: 12.5 volts Where is the problem in the circuit likely to be found?

Technician A says that in a standard SAE relay, the common terminal assignment is identified by the numeric code 3. Technician B says that in a standard SAE relay, the control coil terminals are identified by numeric codes 4 and 5. Who is correct?

Which of the following would be more likely to occur in a truck using SAE wiring codes, if you attempted to connect a gray colored wire with a red colored wire?

Which of the following soldering methods is recommended when repairing wiring in electronic engine wiring harnesses?

Technician A says that each wire used in trucks that comply with the new SAE chassis wiring standards must be identified by a alpha-numeric code. Technician B says that the new SAE chassis wiring standards require that each wire be identified by codes that appear printed every 10 cm apart. Who is correct?

Technician A says that most OEMs today no longer produce hard-copy wiring schematics. Technician B says that virtual schematics are easier to use because they are often interactive. Who is correct?
