ELE 146 FINAL EXAM REVIEW;
QUESTIONS WITH DETAILED VERIFIED
ANSWERS; ALREADY GRADED A; 2026
Different System Level Troubleshooting Methods -
correct answer- Symptom & Cause: Known
issues & Repetitive in nature, worth giving a shot. Isolate
the component causing the issue
Output Back Method: Start testing output and work back
toward the input side of the system
Half Split Method: Split Circuit in half see where fault is
originating from
Shotgun Method: "Follow your instincts", Randomly test
components to isolate the issue
Different Type of Switches - correct answer-
Limit Switches - It senses the position of a machine using a
, mechanical or actuator. The actuator turns on/off the
output. (Conveyor Belt)
Float Switches - Uses a mechanical actuator to sense the
level of a liquid (Toilets)
Pressure Switches - Senses the pressure in the enclosed
system a pressure switch can turn on/off (Its adjustable,
Hydralic press)
Electronic Sensors/Electronic Switch - Instead of relying
on mechanical actuators they have electronic circuitry
that provide electronic signal (Light sensors)
Different ways to Test System level faults - correct
answer- In-Circuit test: Measurement of Electrical
signals (mostly voltage)
Out-of-Circuit test: Testing outside of circuit
Mechanical Test: Physical inspections
