Label solid-state head connectors before unplugging
Solid-state games can have a dozen small plastic connectors between head and cabinet. Most are keyed by a blocked pin hole, but label every one; a plug on the wrong header or turned around can damage the electronics. Dirty, loose, burned or cracked connectors are the most common cause of dead or intermittent features on these games.
