. . . as soon as it powers on. Even before it enters attract mode. And even after game over.
MPU led flashes appropriately (flicker/flash + 6 flashes). In solenoid test, K1 relay does not click. But I wouldn't expect it to, because it has already enabled the flippers.
Everything I've seen about troubleshooting the K1 flipper enable circuit is based on determining why flippers are not energized. So the quick jumpering and continuity tests don't help me because current is already flowing. I did them anyway. I've compared the readings of components in the circuit with other components on the board that are the same and all readings are consistent.
So I've got three questions: Is there an easy way to test the functionality of the K1 relay itself? Could the problem not be on the SDB and if so, what/where should I check next? And, is there anything else you can suggest based on your experience/knowledge?
FYI -- I mention this in case it's related -- In the switch test, all the roulette wheel switches are giving me errors (any of #2 to #5 shows every time I run a switch test), even though the wheel is not giving me any problems in play.
Game plays just fine, except that the flippers are always energized. Guess it's better to an issue that doesn't affect game play, but I'd kinda like to get this fixed.
Any advice would be appreciated.
Thanks in advance.
