Yes, I have researched the issue, no I did not find a solution yet. World Cup Soccer 1994

Here is the problem: The F116 fuse blows after a few moments of actual game play. In test mode, all of the 12 volt motors work with no apparent issues. If I unplug the 12 volt motor for the soccer ball from the motor controller board, I no longer blow the fuse. The voltage to the motor is 14.4 volts.

While I do not have a spec for the chips on the controller board, nothing diode tested unusual. I removed the soccer ball motor from the gear box. I still blew a fuse. All of my transistors on power driver board tested fine, along with the Bridge rectifier and capacitor.

I have found no one come up with a definitive fix for this. It seems everyone just unlplugs the motor for the soccer ball and plays.

i dont want to just throw parts at it with out a definitive reason. Although a new controller board and motor are not terribly expensive.

If anyone has any insight or perhaps something I have missed, assistance would be appreciated.

I'm thinking about just replacing motor. Any thoughts?

Although that's an odd failure for a motor, it's not unheard of and based on your troubleshooting that's where I would go first. My first guess would have been a gummed up gearbox, but you eliminated that. I would still clean and re-lube the gearbox while you've got everything apart.

I think I am going to give that a try. It looks like the motor is sold with gearbox. I am really stumped on this one. I will report back once I get new motor installed.

Got the ole "Check F115, F116, J112 and opto 12V supply" message. Fuse F116 was blown. Replaced and went into test, soccer ball was acting weird. Unplugged soccer ball motor and replaced F116, this fixed the issue. Game can play with soccerball motor disconnected. Ordered new motor/gearbox. I will try to report back when motor is swapped.

I'm in a similar boat. Did the new motor fix it for you?
