I dun fucked up

[AssBurns]

So I went to start my truck and the battery was dead. So I went to jump start it with my other truck. Well here’s where I fucked up. My wife came out as I was doing it and I hooked up the cables backwards. It didn’t even spark enough for me to notice. I had it hooked up for about 20 seconds total. Went to start it and nothing. Looked at the jumper cables and quickly removed them.

So I gave it a minute and tried again with the jumper cables hooked up properly. Nothing.. nothing at all. I also tried disconnecting the battery and hooking up the jumper cables directly to the terminal cables. Still nothing.

Checked the small fuses and the only one blown was the Dome light fuse.

Where should I start repairing my stupidity?

Sounds like you’re blaming your wife.



Get out the volt meter. Check the battery, see what you get, then keep checking down the line. I don’t know if these trucks have a big fuse that controls everything. But I know Honda’s do. I blew the 120 amp fuse on a Honda by doing something silly like this and just replaced it and was good to go. See if it has an ecm or “engine” fuse.

Get on that dvom

Pull the fuse block cover in the engine bay and check everything. There's ALT, AM1, AM2, and EFI that could have shorted.

I haven't dug into the 4 runner but Tacomas have a big fuse in the fuse box in the engine bay

I did that before on my 99 Prelude. It was the main fuse that blew, something like 60,80, or 100 amps. Been too long to remember exactly how many amps, but not that big of a deal.

Self reporting!
That’s a good start.

You're lucky you didn't fry both trucks. Best case you've got a large fuse blown, worst case you've got a toasted ecu.

This is too easy of a thing to fuck up for mfr's to leave the ECU's that vulnerable. A blown fuse is an easy safeguard.

Now thinking about it, it could have been a 120 fuse on the Prelude. I do remember it was huge compared to everything else in there.

Good enough surge could still do it.

I did it on my 1st Gen once. Blew the main fuse as a fuseable link.

Fusible links are a bitch.

I did that once and the CPU burned out

 

[AssBurns]

Well shit.. It sounds like it shouldn't be that big of an issue.

I still feel retarded about it. If i get enough will power, I might go see what I find. Hope it's just a main fuse.

 

[Rockdawg84]

just a reminder, if it is a blown big fuse you have to disassemble the fuse box and remove a bolt that holds the fuse in, you can't just pull the fuse out like the smaller ones. I just did this a couple of weeks ago by changing my starter out without pulling the negative battery cable. I totally know better!

Should this thread be dedicated to all the dumb shit we've done to ourselves? Because I may or may not have a small handful of contributions...

Got any pics of the fuse itself? It’s under the rest of the fuses?

If you want, sure!

It's not under the fuses, but it's bolted to the fuse block. Should be in the main block under the hood. Mine is next to the battery.

Glad that didn’t happen. Jumper cables were warm but never got hot.
