There is meant to be a filter installed when the shaker is installed. The filter goes in between the wiring loom and driver board (back box) and comes with the shaker kit. The filter stops feedback from the shaker motor accidentally firing other coils through the driver board. We do not have any older machines left, otherwise I would post a photo for you. The filter looks like a IDC joiner with capacitors on it.

Ask the distro that fitted your shaker for the filter and the instructions so you can put the filter on. Long term use without the filter could cause damage to your driver board. We have had it happen on a AVLE.

I would disconnect the shaker (or turn it off in the menu) until the filter arrives.

Great game, I am sure you and your family will love it.

Good Luck!

You will not find this on a service bulletin. The instructions come with the correct shaker for SAM. No need for a service bulletin, people just do not install the filter. This is a lot more common than you think, most people do not notice or do anything about it. If you contact the distro you bought the game from they should be able to give you the filter as the filter comes in the kit.

Spike 1 and 2 are different. The filter did not come with the shaker kit. The feedback can destroy the cabinet node board so Stern had to put out the bulletin.
