I have a TWD Pro. I ordered the Shaker Motor Kit 502-5027-00 from Stern. I installed the motor watching a YouTube video. Everything went in fine. I mounted the board on the side cabinet, connected the shaker to the board, connected the board to the connector in the back box and connected the board to the power supply. It doesn’t work.

The one thing I noticed is that the instructions says “for games manufactured prior to August 20, 2014”. I think TWD was manufactured in October 2014. However, the instructions do say Shaker Motor Kit 502-5027-00. Cross referencing to the listing on Pinball Life for Kit 502-5027-00 it says that Kit is for many games, including TWD.

I’ve attached some pics for reference. Any suggestions? Any chance they sent me the wrong shaker?

Thanks in advance.

In the diagnostics menu it does say “disabled”. When I run the diagnostics test, it doesn’t work. How do I turn it on? Thanks for the help.

It says it’s on maximum use in the adjustments menu. Any other thoughts?

I noticed the board on the YouTube video I watched had two fuses. The one I have only has one. The one in the video was being installed in a Metallica.

I was too vague with my description when I said back box. I plugged it in the lower cabinet. Here’s a pic of the plug. I’m wondering if I have the wrong board. I look on line and it seems like the SAM system boards have two fuses but mine only has one.

The Stern site only has two shaker portions. The first is for Spike systems. The other is for SAM. So this is what I ordered:

It’s also the one that PinballLife says works for Walking Dead among other games. Maybe I just need to call Stern.

I tried the coil test. Doesn’t work.

Is the ground tap harness required for the shaker to operate?

That was the problem! Thanks Dawgs. Thanks everyone!

Hi Lash,

I sent you a PM. Here is the picture I mentioned.
