I have a (new to me) Wurlitzer 3700. I plug it in and the accumulator arm spins, never stopping. Additionally, the selector switch latch solenoid does not not engage so you cannot make any selections from the selector buttons. If I manually raise a latch pin and move the magazine from home and return it to run mode the selected record plays fine. Likewise, if I manually engage the latch solenoid I can make a selection with the buttons which also plays fine. In all cases the magazine returns to home after playing. However, the accumulator arm is spinning the entire time, never stopping. I have a service manual but the referenced 'sequence of operations' section is MIA so as a greenhorn I'm kinda shooting blind.

Hi Michael, What are you calling an "accumulator" ? Ron Rich This. Item #5, part number 133499. Sorry, I think I see my mistake now. Probably should have referred to it as the 'Selection Accumulator'? Attachments:

Hi Michael,
I would normally have referred to that as the "write-in arm"-- I would've been wrong !
I dono--you will need to look at the schematic in the manual, and figure out what controls that motor--is it relay/switch controlled on that model, or switch/Triac controlled ? Ron Rich

Thanks Ron! This ended up being a sticking RY-2 relay. The keyboard problem is a sticky (dirty) reset button. Works great now! This thing is gonna need a thorough cleaning though!
