how to charge my run-down battery on 2005 GMC Savana 3500

I left my blinkers flashing while I worked, forgot about it, and now the battery is dead. I have a charger, but I am afraid to use it without instructions ... help!

Put the red lead of your charger to the Positive (+) terminal of the battery, put the black lead of the battery charger to the Negative (-) terminal of the battery and then plug in the charger, set the charger to 12 volts and a low amp setting and let the battery charge for a few hours most chargers will trickle down the charge as the battery charges. Perhaps look on Youtube I find videos for all sorts of things there.
According to the owner's manual (which covers jump-starting only), my vehicle has a remote positive (+) terminal located behind a red plastic cover near the engine accessory drive bracket on the driver's side of the engine compartment, below the alternator. The remote (-) terminal is located on the engine drive bracket and is marked GND (Ground).

For jump-starting, the manual states that the black negative (-) jump cable should be connected to the negative (-) terminal of the good (jump-start) battery, with the other end of this cable to the negative (-) remote terminal location on the vehicle with the dead battery, which in this case is a remote negative (-) terminal marked GND.

Given these owner's manual instructions for jump-starting and your instructions, my assumptions are that the battery charger negative (-) cable should go to my vehicle's remote negative (-) terminal marked GND, and that the battery charger red positive (+) cable should be connected to my vehicle's battery red positive (+) remote terminal located near the engine accessory drive bracket below the alternator.

Do you agree with these assumptions, and where is the engine drive bracket marked GND?
i would think you can put the ground almost anywhere, if u cant get on battery or remote term., positive on -battery or remote + term.
