I get nothing. No lights, no crank, no beeping when u open the doors

First off, the battery is good. I've boosted battery and replaced with a charged new battery.

Got in truck to go, crunk up fine. The one minute late it just shut off. The only thig that was on was a vlinking theft light in the dash. If you turned over the key there is no attempt to crank, silence. There were no lights. No door ajar beeping, no radio or normal dash lights. It was late, I did nothing. The next day, I attempted to trouble shoot. I assumed it was the battery. When a boost didnt work, I took the battery ti locals to have it charged. Battery reading good. Still nothing. I bought a new battery still nothing. Even when cables are connected for some time, there is still no lights, horn no power and any such. Whats wrong with it?
