Wtf! Help!

Ok guys,

I recently was having the radio stays on, no chimes, no door ajar problem and I decided to tackle it today. I located the violet wire splice and cut it out and reconnected the wires. Flipped the ignition key into on but not cranking the motor and the new splice worked. Put everything back together and the truck struggled to start and none of the gauges were working. The truck started the first time, but now it hardly cranks over! Please help someone!

This is a 2004 New Body Style. Now I just went to go jump it and it started right up. The gauges started to work normally but why is the battery drained?

Is the battery dead ?

Have the battery stand alone ( at the very least have it disconnected from the truck's system ).
Charge the battery on a 2A setting until fully charged. Once charged, take a voltage reading and record it. This should be in the 13.n range, on the low side, 12.9 / 12.8. 12.6 could be acceptable a battery that is getting to its last legs.
Let the battery sit for 3 to 4 hours, take another reading, should be within 0.2 / 0.3 VDC of the 1st reading.
Let the battery sit overnight and take another reading, should be what the 2nd reading was +/- 0.10 / 0.20 VDC of the 2nd reading.

This should put the overnight ( unhooked ) reading within ~0.4 VDC of the fully charged reading. If the battery is 1.0 VDC off the 1st reading, the battery is not holding a charge on its own, and should be replaced.
