After fitting the Spike 2 speaker lighting kit and updating the game code, the game reports finding a new node during boot but the speaker lights never come on, even though the DIP switches look set correctly.

Speaker lighting kit not detected after install: cycle the node board DIP switches

Cause: The node board's DIP switches were in the right positions but were not making reliable contact, so the node was not addressed correctly.

Checks

• Make sure the game is on current code (it needs network or USB update) so it can configure the new node.
• Check the node's network and power cables are in the correct sockets.
• Confirm the DIP switch settings against the kit instructions.

Fix

• With the power off, flip each DIP switch back and forth a few times and leave them in the correct positions, then power up with the coin door closed so the game can detect and program the node.
