OP
Quoted from rx2006je:
My WCS keeps telling me to press enter to see test report. I push enter and nothing happens it goes into regular game mode. I put in flipper fidelity speakers today and when I got done installing them I turned on the machine and it said check fuses f114 and f115. They were blown I replaced the fuses and the coin door was open and the goalie is moving back and forth constantly, no G.I. lights are on although the fuses are good. When I close the coin door all the solenoids lock on. What do I need to check, I am clueless. I didn’t think a speaker change could/would cause any of this.
GRUMPY can you help?

Short somewhere. U16,U17 and U20 on the MPU are all starting points. Look for wires touching bare metal.
