    I watched this video a long time ago and meant to leave a comment then. It slipped my mind, but I think it's important to set some things straight. I apologize if other comments have already addressed this. The key here is the fusible link. Parts of the car's electronics are fed from the battery side and other parts are fed from the alternator side. If the link is open and you energize the alternator side when the engine is running, the alternator wakes up and maintains 14V on that part of the system. Of course, if you cycle the key, you lose the 14V again. The problem here is that the alternator is working without a battery to soak up spikes and ripple. It's well known that you should not operate a modern car without a battery. Further, if you know or suspect that the car was jumped backwards, the first thing to do is check the fusible line with an ohm meter or, as done in the video, with a voltmeter. If the link is open, replace it before doing anything else, such as energizing the alternator side.

      Thank you.. I need all the info i can get. My car starts but wont drive over 20 miles per hour, then i shut it off wont start for another couple of hours by itself.? I dunno if you will see this, any suggestions

    Have exactly the same issue with my daughters 2009 Rav4. She broke down yesterday, possibly due to dead/dying battery, her 'friend' turned up before I did, jumped the car and killed it. This is the best vid I have seen that not only shows the cause of jumping backwards, but also how to pull that stupid fuse box apart, Bolted in fuse, Only Toyota would do that. Thank you for the awsome hints..

    This is entry level repair which is overlooked 9 out of 10 times by most dealers. There first step would be replace the battery and alternator (because battery light is on). Then, after spending 1000 dollars of your money, are either lost or check the fuses and even then would try to sell you a complete new fusebox assembly because the manual states it's a none serviceable component.

    Just had this happen yesterday to my wife's Rav4. Guy at work jumped backwards and no radio,no throttle response. Had towed to mechanic shop. Told me 470 bucks for new electronic throttle body. I asked if he checked 120 and other fuses. I also stated I wanted my old throttle body parts. Guess what lo? It was now fuses only. Thanks for the video and good info!

    Wow, thank you for sharing the video. What a pain in the rear end just to replace a "big" blown fuse. It should have been designed a little better to be a little less painful to replace. Great video.

    • @scottcol23
      @scottcol23 8 หลายเดือนก่อน

      120A fuses are usually bolted in. Thats why they are called "fused links". They are not really meant to be serviced by the customer. They are just a safety measure that protects against major damage in the event of reversing the polarity on a battery or jumper cables. But yes, this is a horrible design on Toyota's part. I have done fuse links on a Honda before and it was simple compared to this contraption haha.

    Subscribed!!! I have 80% same issue O7 LS460. One would think that after paying so much for the car toyota would put RED CABLE on + connector.
    Here I am with no dash lights, except for Door Ajar light.
    No Crank and No Start
    Start button dimly lit and not responding,
    Key Fob not aknowledged
    Windows halfway down,
    Radio not working,
    Wipers not working.
    new X-tool D7 scanner cant complete Auto Scan over 94%, Lights work fine, battery is discharging and at the accelerated rate too, during scanning attempts now, likely due to scanner draw.
    Tomorrow will try YOUR way, besides what do I have to loose.
    Weeks ago I did order another ECM unit but they send me a completely different one ( it is one with 6 plug ports where my LS460 has only 4 ports) it is going back!
    But It might even not be the issue after I carefully studied Your awesome video! Thank YOU thank YOU!

    @Firecul 4 ปีที่แล้ว +9

    When you used the power probe to feed the fuse box voltage this gave the alternator enough power to excite the windings and activate.
    From that point the alternator was powering the rest of the car. Sometimes you can rev the engine and it can self excite.

    The red and green oiled felt washers are a great idea. Also mark terminals with a red and green paint stick. Batteries are poorly marked. Do not be in a hurry. When you have seen batteries explode in someones face a couple of times you will respect the power in a battery. An old adage: When you are in a hurry you are in danger.

      To be fair, of the millions of Toyota cars on the road, how many ever have their main fuse link blow?
      Now, if they just made it a push-in fuse, the possibility of a vibration or temperature related arc could cause the link to weld itself to the harness and THAT would be REALLY bad (aka, expensive). I've never blow one or seen one blown, but I"ve never reverse the jumper cable either. :-)

      From an electrical standpoint since it is dealing with very high current it is actually a better design to have it bolted because it is a more solid connection and less potential for it come loose over time and develop high resistance which could lead to melting of the terminals.

Went and got a test light and found out the under hood fuse blocks had power but the interior fuse block had no power. Then looked closer at the 120 amp fuse and it was blown. Then my uncle said "Oh yeah when I was installing the alternator it sparked because I forgot to unhook the battery. " Mannnn that would have saved some time but yeah that bolt in fusible link sucked to change out but it was $4 from auto store.

    Dad did the same thing on 2016 Toyota Avalon hybrid and possibly is the same think?

    So the 120 AMP fuse did it job protecting the rest of the electrics.

    Given the very high current flow that can pass through a Charging system fuse and the risk of fire from a bad connection to it its the only way to make a solid low Resistance connection is to bolt it to the power buss connections.. The diodes in the alternator allow huge current flow in a reverse polarity connection situation the alternator would burn up in seconds if it were not for the fuse link..

    I was wiring fog lights and something shorted. Obd dude and radio fuse (i had tapped into 12v+ acc to temp power fog lights) has blown. replaced and radio turns on but now car won’t start no fuel pump prime.. it just cranks. I was doing some troubleshooting and I noticed am2 and efi no 1 don’t have any power. Do you have any idea why ? And should these be powered if the car is on but not started? Thanks

    It pays to buy a lithium jump starter these days as the new lithium jump starters have a sensor that won't let the electricity flow if the cables are installed incorrectly. For a $60.00 jump starter its cheap insurance and you don't need a second car if you get stranded in the middle of nowhere with a dead battery. Jump starters pay for themselves even after a single car boost.
    If you buy a lithium jump starter buy the ones that can be charged with the 12 volt socket and 120 volt wall socket. The better jump starters will have a regular 400 CCA capability with an instantaneous boost button feature that can provide 700 CCA for batteries that have been totally drained. Since the jump starters are used only once or twice s year I would think that these units should last in excess of 10+ years even if you did 10 boosts a year. They are based on the same lithium ion technology that are used in modern day laptops.

      The best feature on Li-Ion jump packs....their storage ability. I just keep mine under the passenger chair. My old lead acid jump pack was a real pain because there was really no place to store it in my car.

      @poor fellow Fancy jumper cables won't work connected backwards either, or some are "auto sensing" and can be connected in any way (but those won't work with a zero volt battery I'm sure) and I'm pretty sure they're cheaper than a lithium jump starter... but then you still need to flag down some idiot to get a jump from...

      Agree...I've got one in each car just in case. Fyi, they say disconnect from vehicle after 10seconds & they aren't kidding. Project truck with no battery I left it hooked to the wires checking for fluid leaks...jump pack caught on fire. It can't handle amps into the battery from the alternator. Luckily I saw it blowing up like a balloon & threw it into the yard before it erupted in flames...I really like the truck 😁

      A diode in line with a jumper pack cable stops the alternator from charging your pack. It won't help you at all if you reverse your cables...

    I'm confused, why was the power restored after applying power to the box with the probe even though you removed the probe? Does doing that somehow bypass the 120 amp fuse?

      Tyler h I suspect he excited the alternator and now the alternator was supplying voltage to the fuse block.

      @tylerh629 5 ปีที่แล้ว

      @@greggdevlin8686 I don't think that the alternator has a direct feed to the fuse box? Pretty sure it feeds the battery which feeds the box. Either way, if it does feed the box then it seems odd that it would go through a different fuse...

    know someone in the late 80's who tried to jump start their car - managed to short the positive connection to the metal casing of the ECU which was located right next to the battery - one bang and a shower of sparks later was left with a very dead ECU. From memory a replacement ECU cost him around £500 and that was with a big discount from another friend who worked at the dealer (would be around £1400 today taking inflation into account)

    My 2009 Corolla was jumped incorrectly. The charger car's battery neg went to my pos and the charger car's pos went to my chassis ground. It's weird. My Corollas horn sounded, like a warning of reversed polarity. I've never jumped it wrong so it startled me. Next I had several blown fuses. AM1(7.5a), AM2 no 2(7.5a), and a few 10A fuses like the radio. Replaced both 7.5a fuses and hot it to start, but then died and the fuses popped again. I don't know what's up

    You're funny. Didn't you notice some fuses had 11V while others had 14V? The 11V ones were tied to the battery. The 14V ones were tied to the alternator. What you did with the power probe was activate the alternator. When the engine was killed the alternator shut down thus the 14V went away.
