Just got my Shaker this weekend. Installation was easy as there are already mounting holes in the cabinet to the right of the coin box. The included wiring was the perfect length to reach the node board on the left side (near the tilt bob).
After installation, I started up a game and didn't notice any shaker motor action. Then partially through the game, all flippers stopped working except for the left one. When the game ended, the start button is now disabled as well (even though it's on free play.) Upon checking the system menu diagnostics, it shows that the node board is not initialized. A light is now lit on the board under the small fuse, which looks to have blown...
Hopefully replacing the fuse will get the game up and running again, but not sure if there's a problem with the motor itself, or what...
