running high current wires through holes drilled in the metal parts of the vehicle (such as a
firewall)?
DC milliamps - ANS When measuring parasitic (standby) current drain with a DMM, which
measurement scale is used?
Between the (-) negative battery post and the (-) negative of the amplifier - ANS When
troubleshooting voltage drops on suspected bad grounds of amplifiers measured under a load,
a DMM shows voltage between points?
AC Volts - ANS When measuring audio output level of an amplifier at the speaker terminals,
what setting should a DMM be set to measure?
It will display the voltage reading, but with a negative (-) sign in front of it - ANS When the
red and black test leads of a DMM are reversed in a DC Voltage measurement, what will the
screen display differently than when they are connected normally?

,Ohms - ANS According to the MECP Basic Installation Technician Study Guide, when
measuring a low current (MUX) ignition circuit, what setting of the DMM is used to determine
the various values of each key switch position?
The jaw should face away from the connectors seam. - ANS How should the jaw of a crimp
tool be positioned in reference to the seam of the crimp connector?
FALSE - ANS For in vehicle measurements, test lights are recommended by MECP because
they always provide a measured, numeric value to the technician. (TRUE or FALSE)

troubleshooting noise problems?
DC Volts - ANS testing for blown electrical system fuses in a vehicle fuse panel should be
done with which setting on the DMM?
Health - ANS What does the blue section of the NFPA 704 Diamond represent with respect to
safety considerations?
Illumination (Switched by the parking lights) - ANS When a CEA standard color code
compliant wiring harness adapter has a solid orange wire (no stripes), what does that wire
represent?
Amplitude, Wavelength, Frequency, Period - ANS Which of the parameter groups listed
accurately describes the components of sound wave?
After the amplifier, before the speaker. - ANS Where are passive crossovers intended to be
placed in the audio signal path?

, Height x Width x Depth (HxWxD) - ANS What is the correct formula to determine volume of a
square or rectangle subwoofer enclosure?
FALSE - ANS The gain control of an amplifier is the same thing as volume control...(TRUE or
FALSE).
18 - ANS A fuse or circuit breaker should be placed on the power wire no more than
__________ inches from the batter or power source connection point?
8 Ohms - ANS What is the nominal impedance of a Dual Voice Coil subwoofer of each of its 4
ohm coils connected in a series?
FM transmitter (modulator) - ANS Which one of the following methods is the lowest quality
of audio signal input for an AUX source input?
Decreasing the Noise Floor - ANS Damping materials (Sound Deading) can increase dynamic
range in a car audio system by which method?
Use a polarity tester to pop speaker when removed and match the wires to the terminal -
ANS When correct polarity of factory speaker wires is unknown during a speaker
replacement, what is the MECP recommended practice to determine this quickly?
Vehicle Body Control Module - ANS When a technical support document references a
connection at the BCM... to what is that terminology referring?
An aging or weak transmitter battery - ANS What is the largest single cause for the reduction
of transmitter range in a vehicle security system?
Negative Polarity - ANS Sensor inputs on a vehicle security system are typically which polarity
or configuration
