I recently picked up a STTNG Shaker Motor from another member. This is an after-market mod created by Martin at Pinbits.
It runs off of tapping into the first Flasher wires in the back box (red and blue) and is grounded in the back box (black wire). Then runs to a small board in the main cabinet, which in turn connects to the shaker motor.
I installed correctly - and it worked for about half a game, then stopped. Fuses are okay, I believe, Flashers work.... Figuring it had to do with the Flasher wire taps, I installed new wire taps. Still nothing. No red light on board, which indicates power. I then directly spliced in the connections, knowing how inconsistent wire taps can be.
I checked the voltage with a multimeter, and between 8-10 DC Volts are reaching board - 10 volts at source - 8 volts by the time it gets to board. (I know the flashers are supposedly run on 20 Volts - wondering if this is my issue?)
The other option would be something with board.
One other thing, it has turned on and worked briefly a couple times... Almost like the correct power somehow got through - or stored up on board?
I've contacted Pam at Pinbits several times - no response from them.
Anyone have any insight...
