  • In this video I will go over how you can read and make sense of an electrical wiring diagram, I will use diagrams for an evap purge solenoid and electrical diagrams for a crankshaft position sensor, camshaft position sensor, manifold absolute pressure sensor and the throttle position sensor as on example. After this video you should be able to identify wires, connectors, splice joints, fuses, relays and other components when looking at a wiring diagram.

Usually...the left lets u live a life of anything goes without a one true creator and savior god, jesus and holy spirit.

    Hey R&R I’ve watched your channel for years. Fantastic to help demystify automotive issues. & your humour is a great ‘circuit breaker’. Your long reach ratcheting wrench’s have been a game changer. Doesn’t matter how many power tools I’ve got - they’re the 1st tools to go in the bag if I’m out. I loved my Audis. But too expensive to keep on the road. I now have 2 new VWs as family dailys. But have collected (somehow) 3 Saabs & 15 Suzuki Vitaras (Geo tracker). 2 Saabs are convertible & 8 Suzuki’s are soft top. All aged between 1980 - 2002. To be fair - things have got out of control. & yes. My wife is still with me. I’ve just joined your Patreon account. Easy decision. Keep up the great work. Cheers from NZ. 🤙🤙🤙

  • @weemanling
    @weemanling Před 2 lety +6

    Something very important that I think was missed is that the diagrams are always drawn with the car "at rest". Meaning the diagram shows what position components like switches and relays are in when the car is turned off. It's important to know because once components become energised (car turned on), then things like relays will turn on and make other things live.

    R&W Sharpie!? I find that a highlighter is much better cuz you can still read the underlying diagram. And they're available in many delightful colors. Which is actually very useful for highlighting different contiguous conductors. You can use coolish colors like blue or green (I've yet to find a black highlighter, er, lowlighter) for grounds or ground-side switched wires, and warmish colors like red, pink, orange for always-hot, switched high-side, or +5V, and so on.

    I agree that reading a wiring diagram can be confusing for those who have never done it, but they're pretty easy once you know what you're looking at. The problem today is getting your hands on a wiring diagram in the first place.
    In the last 30 years, automotive wiring has gotten so convoluted that the diagrams in the back of most DIY repair manuals (i.e. Chiltons or Haynes) are nearly worthless. We went from being able to put a car's entire wiring diagram onto 3 or 4 sheets to needing a wiring tome of dozens if not hundreds of pages just for one vehicle. Hell, just finding a Ford diagram for which fuses are what can be a pain.
    What most of us need is a diagram of the system that we are currently working on.

    • @Mach141

      all manufactures have tech info websites that you can pay like $20 for one days access, and look through as many wiring diagrams as you want. You used to be able to download the info. as well but they dont allow that anymore. But you can print or screenshot the entire manual if you wish.

    • @maingun07
      @maingun07 Před 3 lety

      @@Mach141 Yeah, I tried that once. Granted it was a few years ago and I don't remember the name of the website, but it was highly recommended by everyone I talked to.
      I paid my 20 or 30 bucks for 3 or 4 days of access to a "complete" wiring diagram. I don't recall which vehicle (it wasn't my Tacoma so it had to be a US vehicle) or which system I was working on. Anyhow, the website explicitly stated that it covered that system on that year of vehicle. On the diagram it clearly showed a wire going to that system... and that was it. No further details. I carefully examined all 70 or 80 pages of diagrams. Nothing. Half a week and at least $20 wasted.
      Before I cough up money again, I want some assurance that the information I need will be there or at least some kind of refund.

I have a 92 Geo Metro 3cyl. 250k mi. Runs rough & smokes. I'd like to take out the engine & get it refreshed by a machine shop. I'm not entirely sure what to ask or expect especially in prices. The vids I do find are more surrounded around high performance. As are the shops here in San Antonio. That's not what I'm after. I just want a basic. Honing of cylinder sleeves. Checking crank & cams & bearings & maybe polishing crank. Maybe a few more things but again not sure and like I said most vids are for aimed towards racers. I'm actually more interested in a optimal mpg build. What would you recommend? Thank you.

If you're looking at wiring diagrams, you'll almost always need to know where the specific connectors, splices and grounds are physically located in the vehicle.

    Thank you so much for this video! Its super helpful. I was just wondering if anyone has some feedback/ advice for my current situation: I have a 97 chevy van that has a lot of wiring issues including no brake lights, turn signals or hazards. After checking out my wiring I realized that previous owners had totally DIY rewired a bunch of stuff so looking at the wiring diagrams isn't really helpful anymore and I'm super confused on where to go from here. I don't have money to take it to a shop and I'm trying my best to fix it myself but I'm just really confused on how to even approach this project since I can't use a wiring diagram and my wiring is pretty mickey moused. Does anyone have advice on how someone like me with basically no autoelctircal experience could work on a project like this? I know it's a kinda vague question but any feedback is welcome :)) and thanks in advance

    The T.I.S. has some great wiring diagrams. Electrical is my weakness.

    Hi, i have an issue with headlights on my 04 Camry ( Australian built ), they don't work. there are 4 fuses, 2 for each side and none have power. The head lamp relay works and has power IN but the out side shows nothing, ok, but when I connect the + lead of dmm to battery and -lead to the out side of relay socket I get a reading. Is this normal ?
