Ruined my electric system, need help

[nonickatall]

Hello folks,

I was on vacation for four weeks and wanted to start my truck up again today.

The battery was dead, I took another battery and a jumper cable and wanted to start the truck. I connected the cable and stupidly didn't look properly, because I was in a rush and connected the battery the wrong way round. I am an Idiot...

I then got into the truck and noticed that I had no electricity. Then I got out again because I thought the cable wasn't connected properly and saw smoke on the battery.

I immediately disconnected it and then connected the battery the right way around. After that, the truck also started, the engine is running now, but I have various problems.

The central locking no longer works, the radio no longer turns off. The ABS and the airbag lamp light up. I have absolutely no gauges on the instrument panel, all gauges such as oil pressure, battery charge, radiator temperature remain at 0.

Does anyone have an idea what I may have destroyed there and where to start looking?

I could get really desperate right now and slap myself...

Thanks in foreward for your support....

Check your fuse box and see if you blew some fuses.

 

[Tonyrodz]

I'd check for any melted ground wires.

I would get a brand new battery first and see what happens.

I fixed my problem, it was only a 40 amp fuse blown, direct at the battery. Everything works, I could load the battery as well and the Battery seems to be ok.

That was a shock in the morning....

i would not operate the battery Time for a new one..

Why? The battery works, seems to have correct voltage. At the moment it don't seem that the battery was damaged.

The opposite is probably true.
There are these electronics, which should get these crusts from the plates by pulsing current.
I bombed every crust in the battery in one single shot...

you have to kind of wonder about Brent sometimes.....
that 40a fuse was put there to prevent damages in case of doing exactly what you did
should be good to go

Who or what is Brent?

You are absolutely right, the fuse did what is it made for..

In the end of the day, that was one more experience with this car, which make me fall deeper in love with these trucks everyday.

But in the beginning I thought: I am now entering a valley of pain because there is a story, that I had in my mind, happened to a friend.

He once bought a 7 year old Mercedes S-Class, which had the problem, that somebody did the same I did and there was an electrical damage, even an Mercedes Benz Dealer could not find. They exchanged a hole bunch of control units and after 12,000 Euro in "error digging cost", the customer gave up. And this S-Class was for years on the parking lot of this Mercedes Benz Dealer.
My friend find the car by accident and bought it for 3,000 Euro, where this cars were traded appx. 20,000 Euros.

He knew that he find the problem and fixed that, but it was not so simple. As far a i remember, it was a something with the body controller and a fuse somewhere else and a third thing i don't remember .

So this story in my mind my day was shortly ruined.. But after a while and after starting to think calm about the problem, I was looking for the fuses and my problem was fixed...

You can't believe how happy I was....

So this threat is a good example of: That stupid errors can happen, even when you think that you are smart. And it's also a story about: Sometimes you have to trust, what you have, because it's good for you.

Or to say it with GM:

Like a rock....

(bg1988) we are not quite sure our selves, he/she/him/her/it/them sometimes past's some pretty bizzare stuff

Hmmm sadly i don't understand what you mean. I guess my english, with support by Google translate, is not good enough to extract the meaning of this words...

"Ich steh auf dem Schlauch."
Like we say in Germany, what directly translated means:
"I am standing on the garden hose."

So now my feeling is, that i will pass someday into eternity and still not know who Brent is..

Brent is forum member BG1988, they changed the forum layout / format a while back and it no longer displays a "name" under the member id

Wow, thank you... Now I'm fully on the track...

Well I don't know Brent, but I know a lot of other forums, where sometimes a lot of, like you said, "bizarre" ideas circle.

That’s awesome!

an idiot for continuing to use a damaged battery... Get it load tested with a battery tester you will see that it is already damaged

so if I accidentally blow a fuse I should replace everything behind it? sound logic.....I mean why even have a fuse then, just delete them that way when something goes wrong you can just go throw the whole thing away and buy a new one.

I bow my head to you, who knows everything and can diagnose a battery 5000 miles away, with a few letters.

I have a load tester and my battery is fine, I measured it with a multimeter, she has the right volt, I have been driving the car since that happened. The car always starts....

I will sue the manufacturer of the load tester, the device must display incorrectly..

Because if you, great god of diagnosis, say that the battery is defective, then it must be be so.

if you tested it whats the internal resistance of the battery, voltage means nothing..

So what should happen BatteryGuru1988? A nuclear explosion, a total disintegration of the matter of my car?

The battery has correct voltage and capacity and delivers correct current...
And it is a lead-accid akkumulator which not burn down like a lithium-ion battery.

So i will use the battery as long as it does its job. And keep in mind: I am from Germany, we can't just fire people who are doing their jobs because of our laws..
