Hi, I just bought used honda 2002 civic si coupe, it has srs light on since i bought it two days ago...so, I try to reset the srs light using paper clip and it even resetting it but after that i try to try turn on the car and it won't turn on. There is no light whats so ever..no door sound, no lights nothing at all.. So, I boost the battery it turn on and was able to drive home than i turn it off..after few seconds...try to turn the car On and it won't turn ON..I checked battery Voltage...its at 12V..than check the fuse..most are good..even check IGNITION FUSE..does not show power replace it still shows no power..what do you think what is wrong? Help Me out please..

Just now I tried my Dodge Caravan Battery on Civic Si eventhough they have different Voltage but I just wanted to check if Civic SI would pick up any lights or anything..but it is same..no response..Its almost like car has no Power..In the morning..i try to turn the car..and just for 2 seconds Display panel came on than it shut off ever since there is no power..help please

 

Welcome to the forum,it sounds like maybe the battery cables,check for carrosion at the negitive ground point.You might even try the battery from the Honda in the Dodge. To see if there is an issue with the battery.
