Just installed Rottendog voltage regulator board BPS022 as a direct replacement for Bally AS 2518-22 and also Rottendog power module board BPS054 as a direct replacement for Bally AS 2518-54. The machine was working okay before, but I wanted to have new boards as the old ones looked tired. On power up, the two blue wires that come from the transformer and plug into J6 started to burn!! Fuses F3 and F1 blew. On the J6 connector, there are 4 other red/brown wires that didn't get hot. What would have caused that? The machine is on european voltage, the new boards are supposed to be plug and play, so I don't see what I could have done wrong to cause this. Help please!!
