No newer car or older car it was postive cable
If you take the battery cable off it will die.
SOURCE: Battery and Alternator Good. Alternator not working. HELP!!!
djn, I believe you have some accessory that is on when the key is in the off position.
Check to make certain glove box light is not on when the glove box door is closed and the trunk light is not on.
If you have an aftermarket radio or any added accessories make sure they are not wired direct to battery voltage.
If all that checks out, disconnect the battery negative and connect a test light between the battery and battery cable. If the light is on you have a drain in the electrical system. Leave the light connected and begin removing 1 fuse at a time until the light goes out, that will tell you what component or circuit is draining the battery.
Last resort, you may have an alternator drawing the battery down.
Good luck and let me know.

You might have a parasitic drain on your battery. Meaning something isn't shutting off like it should be draining your battery. Your positive battery cable might be shorted to ground not allowing power to flow.

Check ground cables on rear of engine over near the firewall, could possibly have a bad ground, causing everything to shut down. Could possibly be a bad computer, Have the truck put on the computer diagnostic system to have it checked, Dealership should have done this... I would return it to the dealership and get with the manager and complain that the problem is not fixed, if you complain enough they should fix the truck for free. If they stated the truck was fixed the first time, Don't let them say it was not the same problem. you brought the truck there for this issue and it has not been fixed, they should guarantee their work.

Battery drain is a Classic sign of a bad Alternator voltage regulator. Typically internal to the Alternator. Assuming that your are not driving the vehicle for a week and it then drains the battery. If not, then possibly a bad alternator anyhow. I believe that 13.6 volts is the correct charging voltage from an alternator.

Removing either battery cable, thereby taking the battery out of the circuit, with the engine running can cause the alternator to charge full tilt and destroy sensitive micro volt (computer controlled) components; and I've seen wiring harnesses go up in flame from it. You may have a module problem.
