Recently purchased this pinball machine and at first F7 fuse on Aux Power Board was blowing. I checked all coils and disconnected all of them and tested each one and they are all ok. Now F7 is ok and F4 is blowing now. When J12 connector is disconnected the fuse stays intact. Any ideas? Thanks.

Does anyone have a Pool Sharks pinball where they can post a picture of the interconnect board? A close up of connectors J7, J9 and J6 would be very helpful. Thanks!

Bob, THANK YOU! Have you ever seen these Pool Sharks or any other Williams system 11 not want to start up normally until you turn it off and on 2 or 3 times? It's a very intermittent problem. Sometimes you can turn it on and it will come on just fine.
