Hey everyone. Picked up a Jurassic park lost world for a good deal at an auction. Seller knows nothing of machine, got it home and plugged in, start button made noise like a credit happened but no ball kicked out. Was able to eventually get it to play by adding credit opening coin door.
Game seemed to work, but figured I should really open up and inspect before playing long term. There is battery damage to the CPU/sound board, and a jumper line has been installed (see pics).
The jumper line is I insulated and was touching another resistor, which could have been causing some of the issue with operation. I stuck a piece of paper towel under the wire to prevent the short.
My question is this —- would the proper way to see if everything works be to add batteries and play? Or could I do more damage to the machine?
I’m open to trying to fix the battery damage ,, or possibly buy a new board if I can find one. I did find a new one from a European source for 399 euro.
Any and all input appreciated.
