shows what I have. The part of the video where he has to crack the case- I think this wrench is the answer: https://www.amazon.com/gp/prod...A33L0O1J6GMEUP&psc=1

The other bolt looks like you can get a ratchet in there.

I don't think I'll have to remove the fusebox altogether. As a matter of fact, I'm not sure why the guy in that video loosened the mounting bolts for it. Maybe I'm missing something.

OK got it. Your truck is newer and hopefully easier to get to that damn fuse. Mine was a PITA.

That's very kind, thank you. You have diagnostic tools for automobiles?

Both of you would henceforth and in perpetuity earn your SIGforum Get Out of Jail Free Cards.

Yes, we have a really good tool.

He's up to it Saturday. So if you can wait, we'll make arrangements to be there.

If I wasn't in Chattanooga all week, I'd be there tomorrow myself.

Saturday is perfect, actually. I need to make sure I have the parts here by then. I assume my local AutoZone will have what I need or be able to get it PDQ?

The "fusible link" thing, an ABS fuse- what else?

I don't want to order from eBay, and that Toyota Parts Overstock is as slow as Christmas on shipping.

Para-

Whether it's for this incident or future, I recommend Tacoma World's forums for help. I have a '96 4x4 Taco that is just a toy for me (my daily driver is a Corolla), but I've gotten help there on a few issues when I couldn't figure out what was wrong. Good forum and helpful members.

I have sourced from Rock Auto for several Tacoma parts. Got to input your year, model, engine etc. Your Autozone may have the fusible link, if thats faster.

Also if your Tacoma uses a 140 amp fuse, as suggested here, this might be it. If Autozone does not have it, your local Toyota dealer might. I bet they replace these often when customers goof up the jumper cables like I did.

The first link wants to charge 14 dollars shipping on an 18 dollar part. The Amazon link is more like it.

The fuse that's in there now is flat on top, so it looks like the part in the first link. The part on Amazon looks a bit different but in this instance, it probably makes no difference. Amazon says it fits Tacomas, no specifics beyond that, so I take that to mean most or all Tacomas, but that covers a lot of ground. I'm going to call my local auto parts store tomorrow.

Sorry, I haven't received it. Did you send it to my personal email, or did you send it to the webmaster address?

Good idea. Or a local Toyota dealer might carry in their parts dept. Good chance Autozone will have it.

Do any of you have a recommendation for one that's functional but not extravagantly priced?

It's ChiCom, but cheap at $7, and will do what you need to do, and more.

Edit: Looks like SC and Marzy will be coming to the rescue! Way to go!

NAPA carries the fuse.
Apparently it's a standard fuse cartridge, and not specific to Toyota.

The ABS fuse probably blew at the same time. Had it been blown before you'd have had the ABS warning light come on a long time ago.

Very unlikely, but possible, that not all the various modules that control everything were protected by the fuses. Before putting the truck back on the road, check to be sure that lights, wipers, power windows & mirrors (if equipped), etc. still work. It has an electronic throttle, so "goose" it a few times to be sure that still works and that it idles properly (not too low or overly fast). Having had power disconnected from it, throttle response may be "wonky" for at least a few minutes. This may be paranoid overly cautious, but if it should happen, you won't be surprised.

Likely the AM1 fuse, it is the center fuse marked 05 50 at the top of the diagram on the start my car fuse block link below, pull that to see if it's blown.

Its called a JCASE High Amp Fuse, 50A, Rock Auto has good prices, but they are also great for drilling down from your vehicle and getting not only the OE part number but several options and pricing. Also called Littelfuse JCAS50

Link Rock Auto Fuse


Link Start my Car Fuse Box diagram


"What is the AM1 fuse on a Toyota?
In general, the AM1 fuse is the bridge that connects your car's electrical systems and all accessories to the power source. When you start your vehicle, the ECU needs to calibrate sensors to know if all systems are running normally. Feb 2, 2023"

Advance Auto Link JSC50 has it for $6.49, just search the parts page on any autoparts store for JCAS50, you can put in your vehicle info to confirm match but the JCAS50 fuse is used in just about every vehicle.

As far as a digital multimeter, or analog for that matter, pretty easy to use and you don't need a Fluke or Dewalt meter, Lowes Kobalt tools are pretty good, not high priced, you can go two ways, Analog, with a sweeping hand or, digital. A good basic one will get you the information you need.

Link Lowes MultiMeter

I have both the analog and digital Kobalt models that list first if you sort by price low to high. They always have them on sale around Christmas, and similar models at Home Depot if you shop there..

I have headlights and emergency flashers, but not brake lights and no turn signals.

para, were you able to get this figured out?

I also have a 2007 Tacoma and when I bought it 2008, bought the hard copy of the shop manual (all four volumes).

I will have some time later today to research the manual and see what I can find if you still need the assistance.

Figured out? No. I know much more about the issue than I did yesterday but it's going to be at least a few days until it's resolved.

SC and Mars are going to assist. SC says he has a game plan and after speaking with him, I believe it.

The only disastrous thing would be a ruined ECM, which would require a dealership or Toyota-certified mechanic to replace. But, that part is probably OK, because that's what the fuses are for.

Other than the ECM, SC tells me it could be back up within a couple of hours of inspecting it.

Man, what a stupid mistake this was. Actually, two or three of them. This is something, though, which I'll never again have to deal with, I promise you that.

My thought too (but I am also not close).

I kind of recall something int he manuals where started off along the lines of asking if battery jumper cables were connect in reverse. (I had a complicated issue and need to look at all the flow charts).

Good luck, LMK if the manuals might be a valid resource.

Thank you

I scrounged the 50 amp out of the robotics lab and have the 140 here on Wednesday.

I believe I also have the correct wiring schematics for the truck.
