Tech: Wurlitzer 3010 problem

I have two problems with a Wurlitzer 3010. The carousel that holds the
records rotates and will not stop if there are no selection made. The
other problem is when you try to make a selection and a letter is
pressed it stays down for 2 seconds and then the latch solenoid releases
it before you can press a number key. If you press a number key first
and then a letter key they both stay down until the power is turned off.
If I manually select a record from the (pin bank unit?) it will pick and
play the record and put it back when it is over. Then it scan and will
not stop. Any info would be a great help. Thanks Pete.
