Hai guys, well just had the best luck ever, the inside compartment just completely died. No electricity, no lights, signals, radio, nothing just completely shut off. The battery is fine and the fuses next to it are also in order. I do remember disconnecting the negative terminal since I was going under the car to try to remove or fix something but I wasn't near any wiring. Then after I was done and i tried to start it, it just didnt, the alternator nor the started even try to click, and when i turned my emergency lights all i heard was the faintes click but no lights, it was just dead and wellllll if anyone knows anything please help ;w;

Yes, year/model is a great start.

Does the car sit long periods of time or was working fine then bam nothing? What was exact voltage on battery when checked?
Do things outside work like lights but nothing in cab works?

I think it sat for a good hour or less while I was under the car, then when I tried to start it I put the key in the ignition, but i forgot to reconnect the negative terminal back, which when I finished and went back to start it, dead like no lights on inside or out, and me and my dad did check all the fuses from the outside, battery was all good including the fuses. Then when we went to check the fuse box I side the car there was nothing, not a single current running through them, yet again the whole inside is without power. The only thing I can suspect is when I was reconnecting it i might have ended up loosening a cable that runs with the negative terminal. Other than that im stumped lol

Start with Grounds. Of course check anything you did under the car but a brittle ground breaking could explain this. Outside of a bad batter or loose/bad connection to the main dist box under hood.

If you hear a faint click when you hit the hazards then you must have power, even if it is minimal. Check battery voltage.
