Hi guys, it's me again.
While I'm waiting for spare part for fixing my bottom ball popper switch I want to ask you few things about shaker motor.

Mine doesn't work at all and no it's not turned off in the options. It looks like everything is connected but I don't feel it kicking in during gameplay. When I go to the test menu, there is one which fires all functions of a machine in circular matter and it does do the shaker motor but nothing happens.

Is there a way to diagnose this somehow?
I'll be able to send you some pictures of the shaker motor and board besides it tomorrow.

I'm just lost here, where do I start looking in attempt to fix this?

Thanks a bunch!

Thanks a lot for your answer.
I'm currently waging if I'm qualified for this fix

I just got my first pin and fixed few switches and got it in gameplay working condition - woohoo!

I'll try to shoot some pictures for you and please keep the ideas coming

I have to buy a multi-meter - but that is not a problem I need one anyway My last one didn't have replaceable batteries and they died.
How should I approach testing the motor with multimeter ?

Thanks a lot guys for help!
I'll try to take off the motor to see if it functioning (local electrician offered to take a look at it) and then I'll go from there.

I inspected all the fuses in the backbox and they seemed "visually" ok, I'll do them again once I get a new multimeter (hehe previous one was made in china and it was sealed hermetically so I had to throw it away heheh). Anyone knows which fuses are related to shaker motor?

I have the manual downloaded - it's helping me a lot to fix this pin! ))
I'm starting to enjoy it since I fixed the switch problems that prevented normal gameplay

Hey guys, just to keep you updated. I finally managed to fix the shaker motor with a help of local technician. It was the brushes that were wore out. And now it.......shaaaaaaakess ))

Let me just say I haven't yet turned it to arcade settings (it's on lowest setting now!).
It's a really amazing feeling when the whole machine starts to shake and you can feel the movement - really simulates earthquake well. It's pretty aggressive! I might try it on full force in the next couple of days. I heard that their tilt was always less sensitive to compensate for the motor.
