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?
