I just picked up an Eight Ball Deluxe. Overall it's pretty nice, but the 1x 2x 3x 4x drop targets intermittently dont reset. Also the 2 ball drop target drop solenoid does work when this happens. I understand that they are on the same circuit on the Solenoid driver board. I've checked and cleaned all the connections on the Solenoid Driver Board and the solenoid expander board and re-soldered the pins as well. The light and relay on the expander board seem to work fine so I'm guessing that's not the issue.

Just when I think I have it working fine it comes back. Any ideas?

Verify all coils on the solenoid expander circuit are of the two diode variety. That would be the outhole, 1 ball, 2 ball, saucer and both drop target bank reset coils.

If any of those was replaced with a single diode coil you could experience the problem you're having.

Thanks for the response. I was able to verify all but the 1 and 2 drop target reset solenoids. They are pretty hard to get to.

Would that cause an intermittent issue?

It could. Only takes one wrong coil to cause problems.

So I decided to remove the wires from each of the 2 solenoids i was having issues with (individually) and when 1 is disconnected the other works fine. I think you have me heading in the right direction

I'm cautiously optimistic. In disconnecting and reconnecting the solenoid wires, I realized that there is a connector of wires going to the target drop solenoids. I pulled it apart, cleaned it, and reconnected it. We've played for over an hour with everything working

Thanks again for leading me in the right direction!

Spoke too soon - the issue is back. I'm going to bed!

What are the chances that this is a solenoid board issue?

This may not have any bearing on the problem, but just to be sure: you have a regular incandescent bulb in the solenoid expander lamp socket and not an LED, right?

I've read of a few of these games acting funny for that reason.

Have you run through and verified the coils operate in solenoid test?
Sounds like a solenoid expander problem,
Put the game in lamp test and listen for the solenoid expander relay clicking like a turn signal.
Find the dummy lamp under the playfield and verify it is flashing in lamp test and that it has not been swapped out with an LED.

Thanks for the input. All of the solenoids work during the test except for the 2 ball target drop and the multiplier targets reset. Those 2 work sometimes but not other times during the test.

During the lamp test the solenoid expander relay does click in and out. The bulb next to it works (even when the solenoids aren't) and is not an LED.

If you verified all the coils controlled by the solenoid expander have two diodes then I would go ahead and replace Q14 and diode CR14.

These two components drive the 2-ball and the inline bank reset and have probably been overstressed.

To make sure I have the right parts, that is a TIP102 Transistor and an 1N4004 diode, correct?

Quoted from fb_rider:

Correct. The original transistor is probably an SE9302, but it's recommended to replace with a TIP102. The diode is a 1N4004, also.

Well, that definitely worked I replaced Q14 and CR14 and all is good now. I also replaced the caps on the squawk and talk and now all the sounds work as they should. Another thing is I removed the old battery and added a remote battery pack - fortunately there were no corrosion issues on the MPU.

Now I get to start doing things like replacing the drop targets

Thanks again for your help!
