hey

friend of mine installed his batter backwards in a civic si. he got a couple fuses replaced but the car is still screwing up. he said it stalled at an intersection, and the rpm's are fluctuating occasionally. any idea what else might have been fucked up by connecting the battery backwards? could he have fucked up the alternator? any way this could have fucked up the spark plugs?

any advice would help a lot..

thanks

 

Backwards like connecting the positve of the car to the negative of the battery?

 

I would imagine that it should have fried lots of fuses and/or relays... the alternator, I doubt. If its under warrenty I would take it to Honda and tell them the car is fucking up. Is he getting the "check engine" or the "charging system" light? I take that once he connected the battery to the wrong polarities that he got a big spark and he immediatly disconnected it. He didn't try to turn the key, right? What else is the Si doing? Come to think about it he might need a new ECU. Damn, never heard of anyone doing this.

 

 

your "friend" eh?

 

yeah my friend....I'm not that dumb I swear....

Its not under warranty.

so yeah he let some idiot put his battery in for him and I guess he connected everything backwards. he didn't try to start it or anything, just connected it wrong. I wasn't there to see but I would imagine a big ass spark shot out...and now its stalling and shit.

I would imagine there is a fuse that would blow right away if you do this...I know if you put a battery backwards in a $10 stereo it will flip a fuse instead of blowing the whole thing...I hope a car has the same shit....

I don't know though. He says it stalls whenever he stops in intersections now, or whenever he lets the rpms low....

 

Take it to Honda and let them hook up their diagnostic machine to it.

 

time fer a new ecu.

 

My friend did this to his BMW, he needed a new ECU...if it's an old SI, could try to get s used ECU from a junk yard.

 

Just when you think you heard it all.

That's almost as bad as the guy on here that put oil in his radiator and then turned the motor on.

 

Make sure he checked all the fuses and not just visually. He needs to use a test light or a meter and make sure all fuse are correct.

 

how did i miss that?!?!

 

its not as bad as my other friend who toasted the transmission on his 03 escalade ext by trying a neutral drop...(awd)


I was drunk at a party when I posted that...I swear a lot when I am wasted.

 

 

A $2000 electrical systems blows to save a $.10 fuse

 

:sqnteek:

This ranks up there in the top 3 stupidity posts...

If a circuit has reverse polarity protection there should not be a problem. Howeever, I doubt they build that into everything and potentially not the ECU.

He will need to go through everything to isolate the problem but he might as well accept that the ECU may need to be replaced.

 

Aaaahhh, yes...funny shit.

 

You didn't miss it. You posted in the damn thread.

 

LOL,

The fuse system is designed to blow when it is overloaded. Changing the polarity does not overload the system.

A few diodes in the ECU would help fix the polarity issues. but why engineer those cost in when the batteries have DIFFERENT SIZE POSTS!

 

never underestimate the stupidity of people.

 

That's what I was thinkin' when I posted it.

 

Sell the car, this thing is now a permanent home to at least a dozen gremlins now.

 

CHeck the side of the car for those little thermostat thingies like turkeys have in them .When they pop the bird is done so is this Honda LOL)

I'll pass on your expert advice.
