When plugging in your touchpads, polarity matters!


Ground Tabs

If you have ever looked closely at the banana plugs on your touchpads and backup buttons, you will see that there is a ground tab on each of them.

This ground tab indicates that the ground wire (black wire) is attached to that terminal. On the deck cable, you will notice that there is a red and black collar on the plug.

Proper Connection

For the touchpads and backup buttons to work properly, the black wire needs to plug into the black collar and the red wire needs to plug into the red collar on the deck cable. In other words, the ground tab needs to go on the black collar.

Check that you have everything plugged in correctly.  Make sure that the ground tab points to the middle of the lane box, like this:

Plugging the connectors in properly means the ground tabs line up with the center of the box. Just make sure that you have the touchpad plugged into the PAD side and the backup button plugged into the BACKUP side!

What happens if the polarity isn’t correct? If it is just on one touchpad, you might see it work intermittently. Plugging in multiple touchpads incorrectly can cause interference. This can cause several to work intermittently or not at all. You may notice that your pads just don’t seem to register hits all the time. The first thing to check in that case is the plug polarity.

Repairing the Connections

If the collars on the deck cable are broken and the connections are rusted, you might want to consider replacing the boxes on the deck cable ($85/box) or replacing the entire deck cable. Especially if making sure the pads and buttons are plugged in correctly doesn’t correct the problems you are having.
