Seeburg SE100 not picking up selections

[billt]

I am working on a Seeburg SE100. I rebuilt the Control Center, Amplifier, Credit Unit. I cleaned and adjusted the detent switch, the tormat unit, and Selector. The jukebox worked perfect everytime...The box was transported by truck 8 hours and taken down to a basement.
It played perfect for about 50 songs. Then it would only play 1 out of 3 selected. Then it played no selections. When you write-in with a battery it picks up every selection as it should. Turn it off for a few hours and come back, it will maybe play 1 song and then quits working. Everytime you write-in with a battery it works perfect.  Question, What in the write-in circuit would act like this?  Went back and cleaned all the plugs on control center, credit unit and selector, still no help. Thank You, Bill

Hi Bill,
Possibly start by checking out the write-in voltage. The read-out voltage is obviously OK if you can successfully perform the battery test. The write-in voltage is half the value of the read-out voltage but is derived from it.
