What did you try and do with it connected backwards? It shouldn't have done to much, unless you tried to start it, or whatever. Also, what car?

must cars have a main relay or main fuse.

I'd check that first.

the main relay for the civic, is in the engine bay in that fuse box its the big 80 amp fuse im sure that it blew and tats why nothing works

It does sound like you blew the main battery fuse on the car. IT is located in a fuse box in the engine bay, most likely near the top of one of the shock towers. I once blew the battery fuse on my old 89 civic, long story but the same as you i was in a rush. Try looking at that fuse, and check the others within that fuse box. Hope this helps

and hope and pray you didn't blow the ecu, which is a possibility if you try to jump a car backwards.

i changed the reg fuses under the hood
but i didn't know where 2 get the bigger fuses i.e. main relay....i didn't jump start it...i juss connected them for like 4 mins tops....

ur a ****, Main Battery fuse, it a 100amp fuse, the main relay sends power to the fuel pump during start up, it under the dash, it would not have blown. anyways yes check your main bat. fuse, it is the first ( #1 ) fuse in the engine bay fuse panel.

all i have to say is HAHA!!!! its the fuse under the hood...buddy of mine did it to his too... easy fix...takes like 5 minutes...make sure when u do it to disconnect battery, then hook it back up after the fuse is installed...make sure u got pos to pos and neg to neg this time...
