I was recently given a Brunswick Aspen pinball and I'm trying to clean it up, make it work well, and then give it to a friend of mine so his kids can play it. I purchased a kit for it with new rubbers, bulbs, etc...and put all of those on. I cleaned and waxed the playfield as well. Also repainted the legs and put new leg levelers on.

Here's the problem: the thumper bumper doesn't seem to work and the flippers won't activate when the ball gets down to them if the ball has hit the thumper bumper first. The flippers seem to work otherwise.

Anyone know what the problem might be and how to fix it? Alternatively, is there a pinball repair tech in the western Chicago suburbs that could take a look at it and fix it? I don't know much about fixing this machine.

Thanks,
Greg
 
So once it hits a pop bumper the flippers die? Do you have to reset the machine for them to come back, or do they work on the next ball.

Just a guess, but maybe there is bad diode on one of the flipper or pop bumper coils.
 
That's right, once it hits the pop bumper the flippers die. They do work on the next ball.

Cool, I'm thinking perhaps the pop bumper coil. I see that the pop bumper and flippers are on the same circuit in the game, so that might be it.

Any other suggestions?

Thanks,
Greg
 
I would replace all the diodes on the coils and any related to their path on the CPU board (assuming it has one). Maybe its spiking back and the diode is not blocking it. Or Maybe its engaging the tilt feature? But that would probably mean all scoring would die on that ball.
 
Closing this one out...I replaced both the solenoid and diode on the thumper bumper and all is well!

Thanks for the advice!
