Wurlitzer 1050 Select Not working

[chadnic]

Hi all,

I have a Wurlitzer 1050 that the select buttons do not work.  It's almost as if they aren't getting powered as the relay never trips.  Reset button doesn't work either.

Going to the steps beyond selection by manually popping up one of the pins and tripping the switch in back everything works.  The carousel rotates, the record is selected, plays and goes back correctly.

The lights are working on the buttons and elsewhere so there is some power at least in those circuits.

I've re-connected the connectors to the selection area, and checked then reseated the relays and nothing seems to work.  Machine hasn't moved or anything obvious.

Any ideas where to start looking?

Yep-- More info needed --
Was the phono "set on free play" ?
Which "credit (pricing) unit is installed in it ? Ron Rich

[chadnic]

Yes it is on free play. It has the coin register mod 1050 if that helps?

[Ron Rich]

Well, no-- not really- I do not know what a "mod 1050 coin register" is ? What des it say on it, and what was done to put it "on free play" ? Have you read you PM's ?? Ron Rich

[chadnic]

Thank you for the reply. Let me try to be more clear with my info so I can help myself here a bit.

What is printed on coin control box is "Coin Register Mod(el) 1050". There is also a "Free Play" momentary switch on the bottom left with an arrow pointing to the right. This trips as it should but does nothing. It is not the BO / AC type although the Slug Rejector looks ominously like what is on a 3700. Coining the machine up does nothing and never has.

On the Coin Registers there are 8 wires through a strain relief in the front of box 4 from the coin mec and 4 going to the "Credit AC" plug in the Control Box. I haven't ever had to mess with this before so I am not super familiar but looking at the schematic, everything is in place as it should be from what I can tell.

I was in the middle of making selections when it quit. I am beginning to suspect the latch circuit in some way because it seems to me that the "Reset" button should work no matter what but I could have missed something on the schematic, they are fuzzy and I have old eyes.

Thanks for all the help Ron.

Hi Chad,
I don't recall ever seeing one of those "registers"-- Only re-call a BO/AC-- perhaps you have an early, or very late production unit ? Anyway-- if it's the old mechanical type-- only one thing to check-- the "key switch"--if that's OK-- look at the switch(s?) activated by the latch bar coil--- I don't know if you have the leaf type switches or not-- but the one that "over-rides" the resistor, often fails-- I am guessing, and ASSUMING here, that your latch coil is not energizing ?

Hi Rich,

I haven't personally worked on many Juekboxes but this Coin Register is non-standard it seems. The key switch seems to be working fine.

I do in fact have the leaf type switches but I am not sure how to check/troubleshoot these switches. Should I just trip them?

It does in fact seem that the coil is not energizing and I found another post where you suggested "helping" it but that doesn't seem to do anything. Do the coils often go bad?

Thanks

An additional point of info that I found was that the "select" light isn't lit.

I also tried messing with the switches and nothing.  I see what you're getting at with the "Credit" not working because that would explain why there is no power and the select isn't lit.  I can move the "Reset" switch back and forth manually with my hand but nothing happens.

Hi Chad,

Go to our FAQ's section-- READ, the "Hi Newbies", how to post a photo, how a jukebox works, the over-center switch, and the "contacts" posts-- Post a photo of that coin unit and the keyboard switches-- Ron Rich

P.S. Is the select lamp good ?

PPS-- Latch coils VERY seldom fail on these !

[chadnic]

Hi Rich,

Thank you for all the help so far. Things went from bad to worse and now I can't even trip a record manually anymore (it won't scan but the load switch still works fine).

I have a lot of looking to do at this point as it seems I might be having multiple issues. I will post back here when I have some progress or specific questions.

To answer your questions: Yes, the Select lamp is good and was working before.

Thank you for the heads up on the latch coil. It is not the coil, I was able to test it directly and it works fine. Something else is wrong at this point. In the mean time I will get pictures.

Look for a circuit breaker, that has been "tripped"--- Ron Rich

[chadnic]

Hi Ron,

That was a wise tip. I found a -28V DC breaker that was "half tripped" and stuck. I reset it and now the select is working again (the light is lit, I can make a selection, reset key works etc).

The problem that now remains is, a selection is made, and pin pops up, there is a rotation (underneath the carousel) but not the carousel itself and then when it hits a point (I don't know what point) at which the keys reset and nothing else happens. It's like the top of the machine is dead now so I'll keep looking but thank you so much for the direction.  I still can't trip anything manually.

Hi Chad,
How can a CB be "half tripped" ? Either it "conducts electricity", or not (when "tripped") ? Do you have the Service Manual ? Look at the "over-ride" switch assembly-- sounds as if the contacts are not "making" ! Do you know how to properly, "clean/adjust" them ? If not -see the two post on contacts/over-center switches, in our FAQ's section. Ron Rich

[chadnic]

Hi Ron,

What I mean by half-tripped was it was not conducting but pressing it (to reset it) did nothing, it "Felt" normal, like it wasn't tripped. Once I opened up the control box and took it out, I felt it click back into place. I have since replaced it with a spare that behaves better.

I will look at the over-ride switch assembly tomorrow. I do have the service manual among other things for it. I do know how to adjust contacts like this from older video games if they are the same (I've done hundreds) but just in case I will review the post anyway if there is something specific that I may not have run into before.

Hi Chad,
Interesting/thanks--
I do not recall the construction of that CB, nor do I recall ever seeing that happen ? The switch WurliTzer used on the over ride ( and many more functions) is, IMHO, too "flimsy"-- They constantly loose the ability to conduct . Ron Rich
