ANSWERS!! | ASSURED SUCCESS
While the engine is running in a combustion engine vehicle, what is the
primary source of power for the electrical system and any electrical
accessories? - 🧠ANSWER ✔✔The Alternator
what is the MECP recommended practice for running high current wires
through holes drilled in the metal parts of the vehicle (such as a firewall)? -
🧠ANSWER ✔✔Install a plastic or rubber grommet
When measuring parasitic (standby) current drain with a DMM, which
measurement scale is used? - 🧠ANSWER ✔✔DC milliamps
When troubleshooting voltage drops on suspected bad grounds of
amplifiers measured under a load, a DMM shows voltage between points? -
,🧠ANSWER ✔✔Between the (-) negative battery post and the (-) negative of
the amplifier
When measuring audio output level of an amplifier at the speaker
terminals, what setting should a DMM be set to measure? - 🧠ANSWER
✔✔AC Volts
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? - 🧠ANSWER ✔✔It will display the voltage reading, but
with a negative (-) sign in front of it
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? -
🧠ANSWER ✔✔Ohms
How should the jaw of a crimp tool be positioned in reference to the seam
of the crimp connector? - 🧠ANSWER ✔✔The jaw should face away from
the connectors seam.
, For in vehicle measurements, test lights are recommended by MECP
because they always provide a measured, numeric value to the technician.
(TRUE or FALSE) - 🧠ANSWER ✔✔FALSE
what are the 3 MECP recommended steps to troubleshooting noise
problems? - 🧠ANSWER ✔✔Identify, Isolate, Eliminate
testing for blown electrical system fuses in a vehicle fuse panel should be
done with which setting on the DMM? - 🧠ANSWER ✔✔DC Volts

respect to safety considerations? - 🧠ANSWER ✔✔Health
When a CEA standard color code compliant wiring harness adapter has a
solid orange wire (no stripes), what does that wire represent? - 🧠ANSWER
✔✔Illumination (Switched by the parking lights)
Which of the parameter groups listed accurately describes the components
of sound wave? - 🧠ANSWER ✔✔Amplitude, Wavelength, Frequency,
Period
Where are passive crossovers intended to be placed in the audio signal
path? - 🧠ANSWER ✔✔After the amplifier, before the speaker.
