Can someone please help? I have a Wurlitzer 2104. It has been playing with no problem, until very recently. The last 2 times I played it, I have experienced issues. I have the jukebox on free play. The first time I had issues, I noticed there was a delay after I selected a record, before the select light would relight and I could make another selection. It would be a delay of anywhere from 30 seconds to a couple of minutes. Before this, the light would relight almost instantaneous with the selection. I experienced the delay in the selection process for the whole evening. Today I turned the box on and I have no select light and cannot make a selection at all. I have tested the fuses and found all to test good. I tried cleaning the visible contacts, but that made no difference as well. I am suspecting the latch solenoid may have failed, but that is just a guess. When I manually push the rod into the solenoid body, nothing changes. I have not tried to test voltages at any point in the box at this time. I would really appreciate any guidance. One other point to make - this box was not played, or plugged in for the past 2 years. It was in storage while we found a new home, moved and then finished the basement. After starting to play it again, it played perfectly for a few times over a couple of months, then the last 2 times starting having the issues described above. Thanks for any help and guidance.

Hi Robert,
That is usually caused by the switches on the latch bar coil. HOW, didja clean them ? Didja READ the FAQ's section on cleaning switches ??

Hi Ron, Thanks for your response. You helped me several years ago, with an issue I had with a Seeburg I owned at the time. With your guidance and a copy of your Seeburg Mechanism Guide, I was able to clean and restore that mechanism. I don’t guess there is a chance you have published a guide of that nature to cover this Wurlitzer? Anyway, I have read the contact cleaning sticky note in the FAQ section. I probably did the wrong thing when I cleaned these contacts, but given the fact the box had been in storage for so long, I thought the contacts were probably the culprit. I used a thin Marco flexible file (like those used on pinball contacts) and then sprayed the contacts with a Miller Stephenson contact cleaner. Unfortunately, it did not help and I still have no select light, or select function on the box. Given where I am at this point, do you have any suggestions as to how I should proceed? I don’t want to make things any worse than they are, so would appreciate any guidance. I do have the Wurlitzer 2104 Service Manual and Wurlitzer Volume 2 - Dr Know-it-All’s book as references.

Hi Robert,
Glad the mech Guide helped. No--no WurliTzer guides--don't have the knowledge to write it, nor the time !!
Purchase a "burnishing tool" !!
Meter (using a good Analog type meter), the contacts on the keyboard. I think you may find the NC set is not making--Also--look at the resistor in that circuit--they do open occasionally, especially if the Playrac is "set" for free play ( Check the value of that actual resistor--as it can vary due to which brand coil is installed in that keyboard !) Is the coil itself "open"--VERY rare !--BTW--replace it with a 10 watt resistor, if that one is open. HTH Ron Rich

Looks to me that you should be checking the contact in the credit unit that's been "doctored" to enable free play.
Norman.

Hi Norman,
Verrrrrry, Good point ! (or is that contact a "poor point" ? in that itz not making good contact ?? )

Thanks to both for your guidance. Ron, I will order a burnishing tool. When I receive it, I will go back over the contacts. I will check the value of the resistors you suggested as well. In the meantime Norman, I did use the cleaning solvent on the contacts in the Playrac. When I finished, the select light came on as it should. It would let me make selections and the select light would immediately come back on again. The problem then was the selections were accepted, the select light would relight, the turntable would engage, but the box did not select the records. I unplugged the box and plugged it back in and it immediately started selecting and playing the songs I had selected before I unplugged it. Since then, it seems to be selecting and playing fine. I am thinking it is still the contacts causing the issues, but I will get a burnishing tool before I try to clean them any further. Ron, I will probably go ahead and change the resistor in the circuit just to be sure it is not influencing the problem. Thanks again to you both.

Robert,
From what you wrote above, I would look at the "over-ride" switches that should make contact the instant a selection pin is released. Ron Rich

I think I am correct the override switches are located in the actual electric selector and junction box located under the record changer. If that is the case, things might have just gotten more difficult. I have no idea at this point how difficult it is to remove the selector unit from the box to access the switches. In reading the manual, it appears that I would remove the entire record changer assembly, including the electric selector and the junction box. I assume then, I could remove the electric selector to get to the over-ride switches. Do you know if that is the correct way to access the selector, or can it be removed from the bottom of the record changer assembly while still in the cabinet? I can see by the description of operation why you would suspect the over-ride switches as being the issue I described. Perhaps it is not as difficult as it seems. I know in the past, I have found most assemblies in jukeboxes are fairly straight forward to remove and reinstall, although the servicing can be quite involved. I am just a bit worried about messing up the interactivity of the assemblies and lift arm in the complete record changer assembly.

Rob, Thank you for the schematics and drawings. I have ordered a burnishing tool and will tackle the job of cleaning the contacts when it arrives. This is my favorite jukebox of the ones I have owned. I really like the sound and the the appearance and I want to get it playing right again. Thanks again for your assistance
