    Default Reversed Polarity - Main fuse blown CIVIC REBORN

    Salam to all and Eid Mubarak

    Have a little problem

    Brother mistakenly reversed the polarities when installing the battery in his Civic 07.

    The car had some sparks at the terminals and headlights aswell as the alternator turned on, he tells me. Only for a second or two, though.

    Got the fuses checked last night and apparently the main 100 amp fuse is blown. Electrician was able to get the Dash lights to turn on somehow, although fluctuating. He said he could fix the fuse itself, however we refused and will wait to get a new one.

    Since it's Eid holidays now, need to ask how bad could the damage be ? Because it's going to be one tense holiday for sure. Is it safe to say that the MAIN FUSE saved us ? Or is the ECU toast ?

    Just had to happen on Chand raat. Tough luck eh?

    Thanks in advance

    Wasalam and Eid Mubarak.

    Well just enjoy your eid holidays. I believe the extreme damage would be blown up Fuses hopefully.

    Negative terminal is a shared terminal and earth which became now positive terminal in your case. Not sure if you did turn ignition and experienced sparks or as soon as you tried to connect the terminal and it sparked.. I hope there is not a major issue except Fuses.

    your fuse saved your other items however you may experience the interior multiplexer go a bit haywire or the radiator fans turn on (A/C control panel gone cuckoo).

    The alternator is toast - best replace it now.

    Happend to me once..i mistakenly connected wrong terminals after i bought new battery as new battery had terminals on opp side compared to old one....car was mehran....its alternator and speedometer cluster got fried within seconds...need to mention that Mehran doesnt come with Main fuse....Maybe your main fuse could have saved your day....but nonetheless point is electronics need just split of a second to get fried...
