      The circuit breaker is a good idea, could have used that when I was troubleshooting why the fuse for the rear wiper and power mirrors kept blowing (turned out one of the wire for the rear wiper is probably shorted to ground somewhere).
      After going through a few fuses I decided to use a small lab power supply instead, since those are current limited, but that was not ideal 😅

    The fuel pump relay you tested is for switching the fuel pump to low or high speed. When the relay is activated, a ballast resistor is added in series with the pump during low load conditions. Otherwise the normally closed contacts of the relay short across the resistor to provide full pump speed when the relay coil is unpowered.
    The relay you were expecting to test is called the 'circuit open' relay or 'c/opn'. The one side of the contacts is constant battery positive, while the other is feeding the pump via the relay previously mentioned.

    Multifuse because there is one assembly step on the line to do it, instead of 10 steps, and the fuse block will rarely fail in use on most cars. The alternator has at least 2 shorted or damaged and leaky diodes as well, you can replace with a new part, or simply take the pain of getting the back end off and replace the diode pack. Would also suggest replacing that test light with a more modern power probe, which gives you benefits of actually showing voltage on the tip, and also the ability to apply battery voltage or ground to it as well, with a self resetting PTC fuse there that will disconnect the test point for excess current flow.

      The SCR in the alternator regulator diode trio was shorted out, it often happens on those oriental car brands. They get a generic size replacement battery with the connector posts on the wrong sides and think it fits without looking at the pole marks. Edit to add: Most American cars have a fuse link on the alternator to save it from cross jumping mishaps and will just roach the alternator cable.

If the local dealer or the auto parts store sells them then buy as needed--they are more expensive and there are all manner of them, so no point stocking something you may never use. But all the traditional fuses are cheap, you just need to find the 3 or 4 fuse sizes with the most common current ratings. Toyota loves their teeny tiny fuses. OH and a metal fuse puller is a smart investment. Those plastic ones turn brittle in the heat over time.

      @@docferringer Every manufacturer loves their little tiny fuses these days..... My old 92 Corsica had normal automotive bus fuses, 2000 Malibu minis on some incidentals (radio, accessories, interior lights, power mirrors, etc) and normals on the important stuff, but 2008 f-150, 2007 optima, 2007 versa minis.....minis everywhere.... They cant convince me some accountant sticking their nose in engineering isnt a thing when its obvious a conversation ala 'we can save 3 cents per annum if we use these instead of those' (and presented on a graph where the y axis is undefined so they can make that upward line as big as they want) definitely happened...... That being said those freaking cartridge blocks are some BULLSHIT!!! Whats wrong with a maxi? or a breaker?! FFS that kind of stuff turns me off to brand quicker than anything else.....
      And side note for the home gamers out there: there is nothing inherently wrong with using a larger fuse for testing.....provided you know what you're doing. Yes, you can have a minor short pulling a bit too much current, which pops a 10A but not a 25A, and that can melt stuff, cause a fire, etc (also why a multimeter with a decent amps range is a good idea, or the aforementioned clamp meter, though for DC Id worry about the EMI in the average vehicle screwing with it). If its a dead short, itll blow the 25A too, which is information you can use for more troubleshooting. Its when it doesnt blow you need to be on your toes. Also, NEVER EVER RUN A HOTTER FUSE THAT DESIGNED!!!!! No, not even 'its only 5A more....' THAT IS ENOUGH TO BURN YOUR CAR DOWN! Its 'okay' (for those who know what they're doing) for troubleshooting, maybe even getting back to some form of civilization. But it is never acceptable. Ever. Even doing it for testing is bad, which is why mechanics dont let other mechanics see them do it.....its embarassing.....as it should be. Take one out of something you dont need (radio, turn signals, seat heaters, rear glass heater, door chime, whatever) BUT DONT RUN MIS-SIZED FUSES!!!!! EVER!!!! When it goes bad, AND IT WILL GO BAD, we will all laugh at you. All of us. And we will tell others what you did and why it was stupid so they can laugh at you too. So dont do it. Oh, and put fuses back in the little extra space holders when you use them dammit. If there are unused and unwired slots, fill em with backups. And still keep a little yellow slide pack in the glove box. Its not hard. There is no excuse. In fact, if your next tab is an amazon order, add a pack or two to your order.....do it. Now.

    What bothers me the most is manufacturers reinvent the wheel. Those special fuses could have easily be incorporated separately into the fuse block, slightly larger fuse block. Now if one fuse blows. you have to replace that whole fuse module. And it's most likely only from the manufacturer at inflated prices. Same with fuel pumps. They've made a DIY fuel pump replacement for $100 into an $800 replacement by a dealereship. My PU could have had a fuel pump access panel in the bed but they chose not to install one.

Thieves show up and start destroying as they do. Family finally decides to do something about it or the owner reaches a point where they sell off, die, etc. The growth on the paint is two years of being in the weather/ pollen / under small trees like a dogwood so likely a covid death.

      Ford focus, there's a fuse on the backside of the fuse block under the dash. Just 1, and it was blown. I think it was something to do with the airbag system that would blow and cut power to the fuel system in case of an accident. They obviously disturbed the system when taking it apart.

    SHORT: If the rectifier bridge is shorted in the alternator it could eat 60amps easily. Pull the big wire off the alternator to see, but I can't say why the engine has to be running unless maybe there's an alternator cut in relay. When I was there, GM was modulating the current output from the alternator using the pcm, to help with cold start EPA test #'s. If the battery was really up, the pcm would slowly recharge the battery instead of lay a big load on the engine at that critical time in the start up cycle. Toy? I Duno Nuthin Bout 'Em.

      I'm not necessarily disagreeing, but those diodes normally deal with more than 12 volts when rectifying the three phase AC made in the stator, so I don't see why 12-13 volts from an attempted backwards jump start.
      Don't say "more amps" or "current", as the diode is essentially an open circuit when reverse biased, which means no current, whatever may be available from the battery.
      I won't try jumping backwards on my car to test, though....

The ECM's and other devices often fail because a diode in the circuitry is in revers bias on the power input and when it sees reverse current it goes dead short. CB radios used to do that. If you get a shorted CB is the protection diode in the back of the radio. Same with an ECM but they are potted with epoxy and cannot be repaired in most cases. If the manufacturers would just put in protection diodes in series with the electronics, all this BS can be eliminated. I did that on my big pickup I used to have and jump started people all the time and my electronics in the truck was WELL protected.

    My best pro tip That all the pros already know if you're trying to find A poped fuse just grab a Test light check both sides with the key on you've got one side lit and the other Side is not bad fuse. If nothing's lit up on that fuse Circuit is probably not switched on. Extremely effective when working on af$fords where the fuse box is not labeled and you don't have the owner's manual just check the fuses. And then all other makes And models all just check the fuses.

    It's possible to legitimately repair that style of cartridge fuse instead of replacing it. All that's needed is to solder a piece of wire of the correct size between the two sides. To get the correct fuse rating, you can count out a number of individual strands from a piece of stranded wire, and use multiple strands that add up to the correct total. You'll need to measure the wire with calipers and find a table of wire parameters that includes the _fusing current_ (i.e. not just the service current), but such tables are readily available online if you search for them.
    As an example, I've got a roll of 16awg stranded copper-clad aluminum wire, which internally contains 40 count 32awg strands. Looking up in a table, a single 32awg strand of copper clad aluminum has a fusing current of a little over 5 amps. So for a 10 amp fuse, I'd probably count out three strands, and for a 100 amp fuse I'd probably count out twelve strands. (I'd add one or two extra strands beyond the number suggested by the fusing current, as the current split between multiple strands of fuse wire is never fully even. The first strand to blow in a multi-strand fuse blows at something like 70% of the sum, and once the first strand blows it'll rapidly cascade to blowing all the rest of the strands.)
    Note that if you are gonna do this, definitely use copper-clad aluminum wire rather than solid copper wire. That's probably what those cartridge fuses have in them already, and it fuses at a lower (i.e. safer) temperature, where a solid copper fuse link might get hotter than that housing is designed to contain. For a much more 100% legit way to do this, buy a glass fuse of the right ampacity, crack it open, and using the bit of fuse wire inside it. I'd only buy a roll of purpose-made fuse wire if I was planning on repairing hundreds of fuses this way though, since rolls of the stuff are usually very expensive.

    Had a laugh seeing this video I did the same thing about a month ago with my 2001 Dodge Ram, it's been sitting about 4 years so I decided to try to get it started and moved. Have 3 brand new batteries in the garage all the same well I thought. Dropped ot in went to start It cranks over but won't start After looking at the battery It was hooked up backwards the battery posts on this battery were reversed The battery was for my brother's 2500 Silverado. Grab the right battery try to start it wouldn't start blew the fuses. Always pays to look before you do and not assume. I found that out the hard way.

    Years ago I had a Dimler Sovereign, lovely car, Bought a new battery for it fitted it and everything went haywire,, this model had electric everything. Any how I checked out what I could but am no auto electrician, but luckily for me there was one literally 3 or 4 miutes down the road, so took the car there, (fortunately it started) took the guy less than 2 minutes to find the new battery had been reverse charged! So I left the car with him for a complete check of all things electric and went quite literally across the road to the car spares shop where th battery came from and told them (I knew the guys in the shop well) what had happened was, to my shock they jumped straight on the defensive and said no not having that you connected it the wrong way round! I was quite shocked, I had been buying from there for years using their shop for all my needs for our cars and vans and also things for my racing cars, but I guess they were protecting themselves, anyhow before the conversation took a nasty turn the auto electrician came in the shop, with the battery, and defended me, they checked the battery and apologised, the auto electrician then gave them a long list for which they would have to supply without cost plus his labour, new alternator 4 electric window motors, wiper motor 2 electric fuel pumps, the list went on and they were more than a little shocked at how much the lot would cost them. The guys two pals that owned the shop, went grey, the blood drained from their faces. Then the electrician said, no only joking looks like just the alternator, as nothing else was actually turned on, and a new battery. They got off lightly, but thereafter no battery went over that counter before being checked first.The electrician just took a drink from the shop for his time, he didn't want anything from me, but I insisted and gave him some money for the "tea boat" as we used to call it. That car run like a Rolls, my wife loved it, but so did the petrol stations, boy it was juicy, and petrol has never been cheap here in England. Taught me a lesson I stick to to this day, never take "new" items for granted.

    Something to watch for on some Toyota/Lexus vehicles is the immobiliser. On my old Mk.2 GS300 if the battery or ECU fuse was disconnected, once reconnected the key had to be left in the ignition for 6 minutes to unlock the immobiliser. I can't remember whether it was first or second click, but definitely in and turned for 6 minutes, preferably without radio, aircon or headlights as they'd be draining the battery at that point. If you didn't do that six-minute step you'd get no spark.

    Don't check for fuse continuity using check light pull out each and every fuse and check with an ohmmeter. if you have a suspected short that keeps blowing the fuse use a 12 volt headlight as a load light in place of the fuse. If it lights up the headlight bright its still got a short and won't cause more damage as the light bulb highly limits current. If it starts out bright then dims your ok and short has been removed. Load light system works good for testing ac appliances too just use a 100 watt ac light bulb. And I assume you have an OBD code reader. What code is it throwing?

    It's a Toyota inless it lives on the East Coast and it's a Rust bucket. 9 times ot of 10 its something someone caused. Like a blown fuse. Or a mouse Chew. Most problems I find with Toyota. Is there owners and tow truck drivers. Engineering is solid. Compared to other manufacturers where anything could be suspect. A test light and a good visual inspection Will normally achieve results in finding faults. Great video . I have run into the same issue before. And potentially could cause someone to go down the rabbit hole. And waste about your money.

  • @topherd1011
    @topherd1011 11 месяцев назад

    Yes… that is a fuse … and it can blow if you jump start your vehicle the wrong way (much more common) or from age. I almost guarantee it’s the former, not the latter. ALWAYS read your manual before jump starting your vehicle. There are SPECIFIC ways to jump start different cars. They are NOT all the same! And in a modern Toyota, you will NEVER hear a fuel pump. NEVER. They do not operate that way. They operate/start based on signals from the cam and crank, THEN fuel is added! So when you’re listening for the pump when you switch it to ON… you’re just wasting your time. They don’t work that way. Hope this helps someone!
    (That fuse or fuse block.. whatever you want to call it, needs replaced either way.. no way around it. You need to order it from the website if you don’t have a dealer nearby)
