okay so check it out
on my s5
i swapped a new chassis harness
i connected everything
and all
but i accidently put the battery backwards
so i blew my main fuse by the strut tower
so i bought a new one and put the battery on
and more of my interior turned on
my tach gauges re arranged themselves
now my idiot cluster has all lights on
and my car wont start
hence it wasnt starting when i put the battery backwards
i turn the key and i hear a click
i charged teh battery
but it still wont turn on its really pissint me off
i dont know what the problem is
so can anyone help me out?
they know what might be wrong?

 

oh and check this out
also
when i turn the lights on they wont flip up
and everything else lights up but the headlights
iono wtf is wrong with that
but if i use the switch on top of the light switch the fc's headlights move up
so yeah idk whats wrong

so yeah
gurus come to my aid

 

so on the new harness
under my tach etc
by the ignition
there are some wires i didnt have before they arnt connected
could that be the problem?

anyone help me out

oh and since i got my new harness
my drivers side power window works
but the only thing is that
my passenger side doesnt respond
from either side

so my problems now are
engine wont start
headlights will only flash for FTP lenses but with light switch they wont flip up and illuminate
and my passenger door isnt responding help me out will you guys

 

since i had the battery backwards
could that have done damage somewhere else to the car? besides the main fuse that got blown but i replaced already

 

Sticking the battery in backwards can fry a lot of things. The ecu will probably be toasted and require replacement, which could be why you're seeing all sorts of odd instrument cluster behavior.

 

well
my idiot cluster
fixed itself now
it only shows what has to be shown
but it shows the check engine light
and whatever i have on
soo any idea what could be the problem?

 

You've more than likely blown more than just the Main engine fuse. Check ALL your fuses just to make sure they're all good. I also wouldn't be surprised if your ECU did happen to get a little cooked, although I'd check a lot of other stuff before I assumed it did, cars have failsafe's for stuff like that.

 

well i highly doubt ecu would get fried because of the backwards battery incident
its on a different harness
plus my idiot cluster would not show or anything because 150amps against a 30amp would just blow
so yeah

any ideas

 

I would be very very surprised if you didn't smoke the ECU if you tried to start the car with the battery hooked up backwards.

And you have a bad headlight switch... (which also could be damaged from hooking up the battery backwards).

And your thread title sucks. Post a real title describing your problem when you post threads... not some lame *** title like that you need help. You probably wouldn't be posting if you didn't need help... so why are you using that as a thread title?

 

Dude, you really messed the car up, bad. I can't believe you managed to hurt the car so bad.

Why are you writing in prose?

 

^ You're writing in prose. He's writing in verse. "Prose" basically means "not poetic at all". Ok, I'm nitpicking.

OP: This has come up before. Do a forum search to find out everything you might have fried. Start testing.

+1 to everything said in last 2 posts. Dude...

 

hey i just did the same thing yo did on my 91 NA 7 .. and i was wondering how many relays and fuses are there to check ? at least like the main ones

 

i also did the same thing but i just diddnt start my car as soon as i put the battery backwords my main engine fuse brighted up all red and as soon as i saw that i disconected the battery and the only thing thats wrong is my dash lights and my interior lights wont turn on but evreything else works headlights pop up bright light symbol and turnning symbols turn on its just wierd if ever find out wat happend can u let me kno

 

The previous owner of my car did the same thing replacing the battery right before he sold it to me. I drove up and he was fiddling under the hood. He complained the main fuse kept blowing and wondered if I could help. We righted the battery connections and all was good except the main fuse and the "floor" fuse in the cabin fuse box. Car runs fine. I guess I got lucky eh?

 

How can so many people manage to hook the battery up backwards? Really. I want to know. The stock battery box & cable lengths shouldn't even make it possible.

 

the First thing I did was get some RED Tape,and Black Tape..taped the Cables,near the battery Connections.It sounds Moronic,but is is "idiotproof".red on positive,black on Negative..it is that damn Striped wire that throws ya for a loop!..
