[Jukebox-list] seeburg ccu issue?

[gibson510 at charter.net]

Wsr5 selection receiver, establish credit via ccu, select light comes on and counter solenoid energizes and stays that way. Also established credit only allows for one selection. Press credit button again and select light dims. I attached a different (known good) keyboard selector to Wsr5 and same exact symptoms. I guess i'll be taking the CCU apart and cleaning. It was supposedly removed and cleaned by previous owner only 2 years previous.
Comments?
thanks
