If your air compressor has alligator clips you attach pos to pos of one batt and neg to neg of other battery. You made a 12v battery bank by putting twin 6v into series.
This could work or might not depending on which posts you connect to.
Basic setup:
- The ground (negative) cable from the rig will attach to battery 1 Negative post.
- Battery 1 positive will connect to Battery 2 negative.
- Battery 2 positive will connect to the positive cable to the rig.
You connect posts that have the cables coming from the rig. If in doubt, put a multimeter on the posts to find which combination has 12 volts.
