Summary of "경기자동차과학고-자동차 전기회로 점검"
Main ideas / lessons conveyed
- The video explains how to inspect automotive electrical circuits using a hands-on approach—often phrased like “connector/bulb: is it loose?”
- A key theme is that, during an exam, you may not have access to a battery. Instead, you rely on checks of standard circuits/test points.
- A recurring priority is accurate identification, including:
- Left vs right lamps
- High beam vs low beam
- Specific functions when filling the exam answer sheet (e.g., turn signals vs other lamp circuits)
Core method (repeated throughout)
- Look first
- Then operate/observe
- Then disconnect/reconnect connectors or remove/inspect bulbs/fuses only as needed
- When disconnecting connectors:
- Ensure you reconnect the correct connector
- Confirm it clicks/locks
Detailed methodology / instruction-style checklist (as presented)
A) Headlight circuit inspection (Avante AD)
Setup / observation
- The instructor briefly uses a battery connection for visibility, but notes that in the actual exam you may not have batteries.
- Identify the two headlight sides in the driver’s view (left/right).
Determine high beam vs low beam
- Turn on lights and identify which lamp becomes the low beam (described as the regular light).
- Switch to passing/high beam and identify which lamps illuminate as high beam.
- Turn off low beams and confirm which light remains as the high beam.
Work light / access procedure (to remove/inspect)
- Turn the headlight cover to the left, then pull it out.
- Inspect inside:
- Check for the bulb presence
- Check the connector
- Caution noted in the description:
- If the main lamp/light is removed incorrectly, neither high nor low may work.
Bulb verification approach
- High beam: generally visible from the outside.
- Low beam: may require removing/taking out the low beam component to check (high beams can often be viewed externally).
Critical caution for the exam
- When unplugging the headlight connector, clearly label which wire/function corresponds to:
- Low beam (regular light)
- High beam
- To mark the answer sheet correctly, you must be able to distinguish:
- Front left vs front right
- High vs low
- Avoid mixing them up.
Connector / reassembly logic
- After reconnecting:
- Verify light operation
- Ensure nothing is left incorrectly seated
B) Steering column / interior connector-related inspection (AD cabin/driver seat area)
Remove and access the steering column cover
- Loosen/remove fixing bolts on the column cover area.
- Use the tilt switch movement and pulling technique to remove the lower/cover part.
Connector checks
- When connectors are pressed in:
- If the connector is loose/disconnected, the associated functions won’t operate.
- Verify connectors related to the turn signal / wiper / light switch area (as described for the steering column region).
Reassembly steps
- Reposition the cover under the housing.
- Tighten bolts on both sides.
- Press/align the cover securely and confirm tilt switch alignment.
C) Taillights / license plate lights / turn signal and related interior checks
Access and remove relevant connector(s)
- Identify the taillight switch area.
- Locate the connector behind/near it.
- Press and pull the connector to disconnect for inspection if needed.
Functional labeling for the answer sheet
- The instructor identifies connectors by what they control, including:
- A white connector for taillights and license plate lights
- Another connector for turn signals and related functions (e.g., wiper/related switch per the transcript)
“Answer sheet” check
- Acceptable testing options include:
- Removing a corresponding bulb (front right noted for turn signal tasks), or
- Disconnecting the connector
- Then mark the appropriate item and re-check.
D) Horn / “boundary” (Gyeowun-gye Our Horn) inspection
Horn location and why it’s difficult
- The horn is inside the bumper (left/right bumper sections), so inspection typically requires bumper-side access.
Practical contest method described
- The test center may remove the connector during the competition.
- If the horn is disabled:
- Unplug the relevant portion (phrasing in the transcript suggests connector/fuse-related “shoe/huge” parts).
Safety/accuracy checks while inspecting those parts
- Don’t only check the ends:
- There can be hidden internal damage or cut legs inside the “shoe.”
- There can also be mid-short conditions (broken connection within the middle).
- Use a visual/dark check (glass/illumination is mentioned) to identify broken internal paths.
E) Starting & ignition circuit inspection
Identify starting/ignition fuse/relay area in engine bay
- Locate the starting/ignition circuit and the relevant coil (described by position, e.g., “15-amp” and “fourth from the top”).
- Check the starter relay section:
- IG2, ACC start button, and other labeled elements.
Connector checks
- Focus on verifying connectors are seated/not disconnected.
- The transcript indicates some internal wiring/lines don’t require detailed checking (“ignore and proceed”).
F) Radiator electric fan inspection (cooling fan circuit)
Steps
- Locate the radiator electric fan connector near the radiator.
- Check whether the connector is disconnected/loose.
- Check for the presence/location of the associated relay.
- Look for missing items, including a referenced “40-arm cooling fan.”
Conclusion
- End once connector/relay/fan presence checks are verified.
G) Charging (generator/alternator) inspection
Steps
- Check the L-shaped connector (referred to as the LR connector) for being missing.
- Verify generator B terminal connection.
- Confirm whether the dashboard charging warning light would be affected (implied: charging status indication).
H) Air conditioner inspection
Steps
- Check the air conditioner compressor region.
- Inspect the air-conditioner switch area.
- Verify the connector type/spec is “10-arm type.”
- Check driver-side view where it’s set up with multiple male-arm counts (10, 12, 10 mentioned).
Additional mention
- Airbag presence is noted near the area, plus mention of additional “number 7” air-related components (as referenced in the transcript).
I) Interior lights, heated seats / interior light bulbs
Steps
- Identify interior light components by position (ceiling / driver seat).
- Check whether ceiling interior light bulbs are loose.
- Locate the interior light and verify the correct “second 10-arm interior light” position (as described).
Verify power/related switching areas
- Mentions include power window amp/fuse rating and the power delivery switch area.
J) Power window fuse rating accuracy (“Power In / Power Indo Hero” section)
Key instruction: use the correct amperage unit rating
- The instructor warns that some test-takers incorrectly write fuse labels broadly (e.g., “power in the fuse” without converting/using the correct amp rating).
- You must determine the correct fuse amp rating (examples given: 10A / 7.5A / 25A types).
If a fuse is removed
- The answer-sheet entry depends on whether the amount matches the fuse installed/connected.
Final recommendation
- Re-check and fill the answer sheet using the correct amperage information.
Sources / speakers featured
- Primary speaker: An unnamed instructor/teacher (guiding a student/exam procedure throughout).
- Referenced external source/analogies: “Jeonje-dong raw fish” and “Pyongyang lights” are mentioned as analogies/examples (not formal sources).
- Other named individuals/institutions/channels: None explicitly identified in the subtitles.
