No Power
 

Hello and hope everyone has a great Xmas and happy new year. Well my car's been sitting for a couple of weeks now, so i wanted to start her up to keep things all lube up and all. So i jumped the battery with a jump starter box. It started up fine and die after like a minute cus it's cold outside. So i was like ok so i plug the jumper box up again but forgot to turn the keys to off. Well when i plug it in and turn to jumper box to engine start all the interior lights turn super bright. So i turn it off and turn it back on to try and get it to start. Well as soon as i try to crank it, it just make this bzzz sound and everything turned off, no power to anything at all. I check all the fuses and all but couldn't find a blown one. So now no power when i turn the key at all. Does anyone know if theres a fuse that i might have missed to check. I've checked all the fuses in the front, and main fuses (my main fuse is 100amp but it supposed to be 120amp but work fine before and still not blown) unplug and replug EGI fuse and all but still nothing. Any idea guys???

On my car at least, if the battery was almost completely discharged I could not jump the car - I just got a nasty buzzing sound. Try charging the battery for a while. It may however be fluxored. What voltage is it putting out?

I dont think its the battery at all, even with the jumper box connected, there's still no power when the key is in on position. It's almost like the main fuse is blown but i've check the main fuses by the battery box and it wasn't and that's the only main fuse that i know of though.

Check the connections of both the positive and negative battery terminals and make sure they're seated properly and making a good connection.
