Hello all. So I recently got a Sharkey's shootout a couple of months ago. It had been playing great when a ball when down the scoop near the pops, never came back up, and got a checksum 49FF error (whatever that is). Game was basically stopped, so I turned the machine off, got the ball out and tried restarting it. Same result. I tried going switch test mode and the special Dr setting on this machine and for some reason I can't seem to test anything. The only test that works is lights. I'm testing this with the coin door open and the Interlock switch is out. So I have no idea where to go with this. I can't be sure if the coil test ever worked since this is the first time I've tried it, so I don't know if both issues are related, but seems unlikely. I've done a bit of fixing on the mechanical side, but electrical is where I struggle. No batteries, NVRAM installed. Any help/ideas would be great. Thanks.
