Yo, don't frequent this side of the forums, but I might now because the high demand for pinball repairs needed. Four emails from different clients poured in today about pinball machines in need of maintenance and repair after I posted my business ad 2 days ago....
Got a client who's sent me a message to come look at his old Earthshaker, says the shaker motor is not responding, even after he replaced it. So right now I'm just preparing a list of things that could be causing this fault.......lol wow that pun literally rolled off unintentionally. I don't know any other symptoms at this moment because I won't get time to look at it till Sunday.
This is where I would start...
- Check the shaker motor's brushes
- Check the voltage output from the High Voltage Output Driver Board
> Test the transistor
> Check for broken/scratched traces on the PCB
- Check the input (signal) from the CPU board to make sure it's turning it on
Those are just what I could piece together from the manual and my own logical thinking skills. I don't have that much experience with pins as I do vids, so I'm just going to ask ya'lls opinions on this matter.
