Question 1

On a wiring diagram, S110 with a ".8 BRN/BLK" means ________.
A) Circuit #.8, spliced under the hood
B) A connector with 0.8 mm 2 wire
C) A splice of a brown with black stripe, wire size being 0.8 mm 2 (18 gauge AWG)
D) Both a and b

Accepted Answer

Consider on wiring diagram, S110 with ".8BRN/BLK".
The "S" indicates the Splice.
In ".8BRN/BLK", the code BRN indicates brown and BLK indicates black.
In ".8BRN/BLK"., 0.8 is the metric wire gauge size in square millimeters

.
Hence, the options a, b, and d are incorrect.
Hence, S110 with ".8BRN/BLK" means a splice of brown and black strip and the wire size is 0.

Question 3

Where is connector C250?
A) Under the hood
B) Under the dash
C) In the passenger compartment
D) In the trunk

Accepted Answer

For a connector the connections are labeled as "C." There are three numbers following C that give the details of location of the connector on the vehicle. The numbers between 200 and 299 are situated under the dash. So the connector C250 is situated under the dash.
Thus, the correct option is

.

Question 5

All switches illustrated in schematics are ________.
A) Shown in their normal position
B) Always shown in their on position
C) Always shown in their off position
D) Shown in their on position except for lighting switches

Accepted Answer

All switches that are drawn in schematics are drawn in their normal position. The first position can be of an open switch which is labeled as N.O and the other can be a closed switch indicated as N.C.
Thus, the correct option is

.
