Yeah, your PCB is in a reset loop, and/or the CPU is running junk code, as that's what makes the counter click. Could be a number of things. First thing to check would be the ROMs and CPU, then start digging into the bus. (If you have any other game/PCB that has a 6502 processor, you could try swapping that yourself, if you wanted to try it.) You can also try reseating the ROMs.
I could look at it for you, if you can't find someone else. I don't have a WL cab, but I should be able to troubleshoot it on the bench, as I repair other raster boards that way. I just won't be able to play-test all of the functions. But given that that's not your issue here, I can check the ROMs and should be able to figure it out enough to get it running.
You can ship it up to me for about ten bucks, if you don't want to drive up.
