Hoping for some advise. Rescued a Bally circus from the trash recently . Got it home and turned it on. Lights didn't come on . Tapped the left flipper and they came on for a second .would stay on if I held them . 3rd player score reel wouldn't reset . When. It finally zeroed out , it would start cycling through again . Sounded like a motor was still running even when the reel was at zeros . Then it would start cycling through numbers again . I took a video of the switches in the back if it's possible to upload . Any ideas where I should start trouble shooting ?
