When wiring it up, the charger needs a 12v input. Red is positive and black is negative (reversing the polarity can damage the puck). We recommend wiring this to an ignition-switched circuit so you don't drain the battery over time.
- Remove the gripper posts. If the post comes off the set screw, remove the set screw as well. Usually the post and the screw come off together. They're loc-tited on so you may need to use pliers, which is why the upgrade comes with new posts.
- Install the bottom adapter first (the one without the puck) by threading the two allen bolts preinstalled in the adapter into the now empty gripper post holes. We recommend a tiny amount of blue loc-tite on the screw. You can get an allen key in there without removing the new gripper posts. Just tighten them a little past snug, no need to make them extra tight. The larger radius curve goes toward the puck, the smaller radius toward the click wheel.
- Install the puck holder the same way.
