A-6 Electrical ASE Test Preparation


Wire Repair

1. When applying solder to a splice connection,

the solder is applied directly to the soldering tip.
the solder is applied at the instant that the heat is applied.
the solder is applied to the splice after it has been heated for a few seconds.
both a and b.

 

2. The most commonly used solder for soldering a component or leads is:

20/80 bar solder.
60/40 resin-core wire solder.
40/40 solid wire solder.
50/50 acid-core wire solder.

 

3. Technician A says the AWG gauge number for a copper wire is determined by the length of the wire. Technician B says it is determined by the type of insulating material used on the wire. Who is correct?

technician A only.
technician B only.
both Technicians A and B.
neither Technician A nor B.

 

4. Technician A says the effect of temperature on resistance is a factor in wire size selection. Technician B says wire must be large enough to carry the amount of current necessary for the circuit to operate correctly. Who is correct?

A only.
B only.
both A and B.
neither A nor B.

 

5. Two technicians are discussing a terminal end repair: Technician A says this type of repair can be done with a pair needle nose pliers. Technician B says only a specially designed pair of terminal crimpers can be used. Who is correct?

technician A only.
technician B only.
both technician A and B.
neither technician A nor B.

 

6. Two technicians are discussing a splice repair: Technician A says when replacing a section of wire you must replace it with wire of the same length and gauge. Technician B says when repairing a fusible link you can use standard wire provided it is the same gauge. Who is correct?

technician A only.
technician B only.
both technician A and B.
neither technician A nor B.

 

7. Technician A says solderless crimp connectors are normally crimped to the wire with needle nose pliers. Technician says solderless crimp connectors are the preferred repair because they provide excellent protection against corrosion. Who is correct?

technician A only.
technician B only.
both technicians A and B.
neither technicians A nor B.

 

8. Wire size standards are being discussed: Technician A says in the metric system of wire sizes, the smaller the number the larger wire conductor. Technician B says in the American wire standard (AWG) the higher the number the smaller the wire. Who is correct?

technician A only.
technician B only.
both technicians A and B.
neither technicians A nor B.

 

9. Wiring repair techniques are being discussed: Technician A says it is preferred to use soldered splice connections. Technician B says rosin core solder should not be used on strand copper wire. Who is correct?

technician A only
technician B only
both technicians A and B
neither technicians A nor B

 

10. When splicing a broken wire back together and a water proof connection is preferred you can use.

none insulated butt splice wrapped in silicon tape
crimp and seal butt splice sleeve
insulated butt splice
splice clip wrapped in electrical tape

 

11. How far must the wires be stripped when using a splice clip:

7 mm. (approximately 1/4 inch)
10 mm
(approximately 3/8 inch)
15 mm
(approximately 1/2 inch)
30 mm (approximately 1 inch)

 

12. Metri-pack connectors are:

posi-lock to seat
pull to seat
push to seat
either pull to seat or push to seat.

 

13. Crimp and seal splice sleeves should be used:


when you don't want to use electrical tape
when the insulation has be burned off the conductor
when the circuit is exposed to the elements
when a temporary repair is needed

 

14. Shrink tubing is used:

to repair a fusible link.
to protect a soldered splice joint.
to cover an insulated butt splice
when the insulation has worn away but the wire is still serviceable.

 

15. A poorly made electrical connection:

has a much higher-than-normal resistance.
can produce excessive heat when normal current flows through the circuit.
can reduce the total energy normally available for the load.
all of the above.

 

16. Two technicians are discussing a splice repair: Technician A says a splice clip should be soldered and heat shrink tubing used to insulate the repair. Technician B says soldering is never performed when a splice clip is used. Who is correct? 

technician A only.
technician B only.
both technician A and B.
neither technician A nor B.

 

17. Two technicians are discussing a splice repair: Technician A says silicon tape is not as good as a repair as heat shrink tubing is. Technician B says silicon tape is better than electrical tape for electrical repairs. Who is correct?

technician A only.
technician B only.
both technicians A and B.
neither technician A nor B.

 

18. Two technicians are discussing a splice repair: Technician A says an insulated butt splice connector is a good repair for a broken throttle position sensor wire. Technician B says that insulated butt splices are for temporary use only and should never be used as a permanent repair. Who is correct?

technician A only.
technician B only.
both technician A and B.
neither technician A nor B.
