    Unhappy Hooked jumper cables up backward

    My G20 sat for quite a while and I needed to jumpstart it. For the first time in my life, I hooked them up backward. To make a long stort short... I replaced battery but now car won't start. Everything in cab is dead..radio, lights everything. The headlights still work. What did I fry?

    You probably blew every fuse existent to your car and man-kind. A new battery may be in order. And a set of fuses. Check the ones by the steering wheel or driver side dash.

    you hava p11 your min fusable links may be part of the positive turminall seems like all the newer nissans are doing this. calm down your ecu does not control lthe lights and such. I have fixed quite a few cars that were toed in for the same thing so you are not the onlyone out their. ll have been really minimal damage. I find it more frequent when some one hs aftermarket terminls people just dont know what is what.
    Om just glad your cars battery did not blow up in your face. you hve to say their is quite a load on the bttery when ou are useing a power sorce in the opisit direction. It is like creating a super heating ellement all fuses in the car should generally be alright in more cases as if they were of they would not ever se a load

    I jumped my NX backwards a few years ago and it had the same symptoms. The fusable link on the positive battery cable was blown. The only place I could find it was at a junkyard and once replaced everything was fine again.

    see you are not alone.

    i have never done it. I also have my battery frunk mounted and i have makered my hot wire so i can tell what is what just in case. but it would not be to much fun jumping my car from the trunk.

    But hey shit happens people make misstakes I make them all the time. not really on cars but in other things in life

    ROFL dude........ not so.

    A buddy and I were working on my dodge avenger (drunk......heres where the trouble started) and I was on the other side of the bay buttoning up a couple last things and my friend put in my battery........ BACKWARDS....


    I got in the car turned the key forward and EVERYTHING worked but my windshield wipers were stuck on.... so I figured it out flipped the battery back around and all that was blown was TWO things:

    A big "alternator choke" fuse
    And my HVAC... heat a/c all of it.... lol

    what you did was blow the battery fuse under the hood. i did this about 2 years ago and all i needed was a new fuse, so don't worry too much.

    Hey guys... I replaced the 100A battery fuse and a few other 7.5A fuses and everything is up and running again. Thank you very much for the info. I would have had to tow to get service and payed dealer prices for the fix.
    Thanks again... I couldn't have done it without you.

    to revive this thread, well looks like my roommate did this to my car as I was going upstairs to get a wrench. nothing in my car is working. I found the fuse box for the battery and saw the battery one... ok so now for some dumb questions, how can I tell if a fuse is blown? are there any tricks on taking out the fuse? do I need to use needle-nose pliers or something? sorry for all the noobie questions. PLEASE HELP

    yeah battery fuse is a byatch to take out the only way i could tell that i blew it was because there was some crater marks on the little plastic window haha other than that you can use a voltmeter and see if current is going from the fuses on the left side of the battery fuse to the right side of the battery fuse.. if no volts on one of the sides then i means battery fuse is toast and not carrying current to the other fuses

    thanks man, but I have a p10. I got the fuse out but the mechanic told me the fuse looked great just by looking at it. he said to check the other fuses to see if the blew and if that's not it it is by ECU...let's just hope that isn't the case
