Hi,
I have a friend with a Wurlitzer 1700. It is not working correctly.
He tells me that when you select a record, the selector arm rotates but plays the same song each time.
The record carousel does not turn.
I am a bit confused and don't know why this would happen.
My manual does not have a troubleshooting section.
Any one have any advice?
Regards
Gordo....

Hi Gordo,
I'm confuzzed by your "terminology", ? Is the correct pin being released, or is the same pin being released, no mater what buttons were pressed on the keyboard ? Ron Rich

Gordo, either of the following are the cause:
1) Pin is not being reset by crank. This occurs as record is being raised.
2) Crank and switch linkage is gummed up and not returning to it's untripped position. One check is to see if various pins from previous selection attempts are up. Another check is to move the crank with your hand and see how free it is.
On those old 104's when the crank hit a pin it releases a linkage that presses down on a rocker in the center underside of the pinbank box. This in-turn actuates two micro switches on the side of the box. These reverse the carousel motor which loads-play the selected record.
Any gumminess in that linkage can cause it to remain in the "trip" position and lead to what you are seeing.
In spite of having owned 3 1800's and a 1700, I neglected to ever get a selection system schematic for those first carousel 104 models. The selection system is radically different from the 100-104 models beginning with the 1900 so I don't have anything to share. But the problem should be easily observed.

Thanks Ron and RobNYC,
Thanks for your replies.
I have not been able to inspect his jukebox and cannot get there for a few days yet.
From what my friend told me it appears that the linkage may not be pressing down on the rocker to cancel the selection. Hence same record over and over.
I also expect the jukebox to need a very good lube as I don't believe it has been used for some time. He has not been in good health.
Thanks for some direction, and I will let you know what I find.
Hopefully something simple.
Regards
Gordon...

Gordo,
Sometimes WurliTzers get "bound against a pin"--this is a sign the "backstop" failed. You usually can release the bind by locking the pin down--just be careful the pin does not get bent--then be SURE that both backstops are clean, and un-oiled !! Ron Rich

Hi All,
Well, it's fixed and working well.
The problem is I don't really know how we fixed it.
What was happening was the carousel was not turning when the selector crank turned.
They were disconnected from each other.
The selector turned and stopped at a (raised) pin to select a record. As the carousel did not turn it played the same record over and over.
We oiled all the parts we could and no change.
So, we manually turned the carousel in reverse, while holding the selector crank stable.
A small amount of pressure resulted in an audible 'click' and they were reattached.
Something was out of sync.
It is now working fine.
My apologies for being a bit vague on the correct terminology, but all appears well.
Thanks for your time and effort.
Regards
Gordon...

Gordo,
You just moved it--didn't you-- well in the movement you did not "prepare it (correctly) for shipment", and carousel jumped off the drive pin--no harm, as you correctly installed it back on, by turning the basket. Ron Rich

This sort of problem results from two sources: 1) Tinkering. Where someone takes off the arch and carousel but doesn't know how to re-couple the crank and carousel. Or they leave the large "C" clip off and the carousel slips upward when the machine is moved on its back. One of the joys of dealing with "home" jukes. 2) Someone spins the carousel fast, it hits a raised pin and the upper crank pops out of the spring catch. People are sometimes fooled by thinking that when they use the service lever it is ok to manually turn the carousel fast to change records. These early machines don't raise the lower crank as the later mechs do. Wurlitzer must have had some calls on this.. RobNYC |

No Ron, I didn't move the jukebox.
I do agree a better description would have helped.
My friend has owned this jukebox for 25 years and is not well.
I told him not to touch anything until I could get there to look.
As he lives a fair way away, it took me a few days to get there.
I think that something probably went wrong (which he tried to fix) and may have made it worse.
I suspect RobNYC (point 2) is very possible.
All OK now and I have left him with instructions to use it regularly and call me if trouble happen again.
Thanks again for your time and advice.
Gordon...
