Just picked up a FG ( my first SS) and the BG strobe light keeps flashing even after a game ends. Tried looking at the schematic but could not figure what triggers the flash strobe.

Already found that a bad solder joint at the coin door relay can cause some fun.

Looking for some help where to start.
Thx

Resolder all the connectors on the aux lamp driver board. If that does not help, then check transistor Q25 on that board and chip U5 too.

Reseated a bunch of connectors and all looks well. .

Do you mean it flashes continuously or at random? It's normal for the flash unit to flash during the occasional attract mode voices, "emperor Ming awaits!"
You can turn that off if you want.

If the flash is going continuously it could be a bad driver SCR.
