Please check my work here. I have the Cointaker Red Tremor Shaker. I installed the shaker in the bottom left corner and mounted the control board above it. I tapped into the top post wire of the coin door with the red wire coming from the control board. I ran the signal wire from the control board to the fifth position in the backbox connector using 22 gauge wire and Pinball life connection tool.

From what I understand the signal wire is also the ground that runs the motor? In the standard configuration there is no dedicated ground for the Cointaker setup - only signal and power on the control board on one end and the other end of the board has a ground and power wire going to the motor, so the signal wire must complete the ground, correct?

Scroll to the bottom of the page to the "Bootflash" section and select the OS8.

I no longer can find the OS8 available on Stern's site.

I installed the Red Tremor Shaker and it works great. I did tone down my shaker a bit by phasing the arms on the shaker about 160 degrees apart. I would estimate that the intensity decreased about 40%; however, I believe the frequency (speed) of the shaker increased somewhat. It is just right now. The shaker adds a lot to the game for sure. I also installed the OS8 sound update just to be sure I did not get the random call outs. Mine had OS3 previously.

I bought the wire harness terminal tool from pinball life to seat the shaker signal wire into the wire terminal in the backboard. I used 22 gauge wire. I also tapped into the power on the top coin door switch as shown in this thread.

I appreciate those that shared the information.

Anyone know if pinbits or anyone else will have the PAL chip available again? I modded my LOTR a few years ago and sold it and now I want to do it again with another machine. If not, I guess I will have to buy an LE model.

Thanks

I think we are talking about 2 different things. Looking for the PAL update, not the shaker motor.

Thank you for that source. I'm trying to decide if I should do a standard and convert it or just buy an LE and be done with it. Does the LE come standard with a shaker?

Just installed my shaker using chips from Matt’s Basement Arcade. Prior to installation I was getting a random call out errors. When I upgraded to ROM 10.2 and did the OS8 upgrade sound issues went away.

This is my second shaker install. The first machine had a red tremor shaker that was at least twice as powerful as the stern shaker, but I went with stern this time just in case the red tremor caused problems.
