Selector Buttons Fail To Latch

Approximately 3 weeks ago my Seeburg DS100 operated perfectly. It has an appropriate free play unit attached and has worked great. When I turned the phono on today the selector light was lit. When I attempted to makle a selection the selector keys failed to latch down. I removed the cover from the electrical selector and as I pushed one selector at a time and then both selectors at the same time it was noted that the latch bar solenoid fails to energize. Since the selector light is on, I assume the manual credit switch is not the cause. I can manually operate the latch bar and can not detect any binding in the linkage, so have ruled that out as a cause. This leaves the latch bar solenoid winding beining open as the most likely suspect that would cause this problem.

I can make selections via the WOM. After I made selections via the WOM, I can now make selections if I press both selector buttons at the same time.

Is there some further testing I should perform to determine that the solenoid is the culprit, and if so what, or at this point should I just obtain and replace the solenoid?

Hi Darrell,
Which "appropriate" free play unit is installed ?
You should first try un-plugging, and re-plugging the free play unit.
If it still fails to latch, remove the unit, and check the start circuit--have someone hold down a button and check at the (round) plug for continuity between ground and the start pin.
If good, and it's the replacement free play unit I sold you, you will need to send it in for repair-if it is, it will be the first one I have ever seen fail--Ron Rich

Good Afternoon Ron

Which "appropriate" free play unit is installed ? (It is manufactured by DJ Systems of Appleton Wisconsin)

You should first try un-plugging, and re-plugging the free play unit. (Tried this problem still exists)

If it still fails to latch, remove the unit, and check the start circuit--have someone hold down a button and check at the (round) plug for continuity between ground and the start pin. (Home alone, will do this when I can get some assistance and report outcome. Are you talking about the round plug from the free play unit that goes into the receiver? Also, how does one determine the start pin (which I assume is on the round plug going into the reciver from the free play unit))


Thanks
Darrell

George,
OK, Look at the Replacement credit unit. Does it have a switch on it ? If so, "flip it" in the other direction and see if that helps. If not, flip it back and try it again--sometimes the switches get 'hit" just a little, and fail to make contact.
The start switch wire comes from the TES to the pricing unit (socket). Pins 1-9
Also, try removing and re-seating the two large "Cinch-Jones" plugs.

There is no switch on the free play unit.

Pulled and reseated both "Cinch Jones" plugs. No difference.

I used Pin #1 from the start switch wire that comes from the TES to the pricing unit (socket) or to the free play unit. Pins labeled 1-9.

Wife held button down and Pin #1 to ground does not show continuity.

Darrell,
You mis-understood--
Read from pin 1 (which is ground if plugged in) to pin 9, which is the "start switch", when you wife holds a number, and letter button down. Ron Rich

Ron

OOOPS

The plug I am testing actually has 11 pins. I checked between pin 1 and pin 9 and with the selector button pushed down there is continuity between the 1 & 9 pin.

Darrell

Darrell,
In that case, It would be my opinion that the credit unit is defective.
You might test it in another one of you phono's, and if bad, send it to the address* on it with a note. I am sure he will repair/replace it with no problem.
* if address is not there, or un-readable, PM me---

Ron

Your opinion is usually correct.

Thank you for guidance, will let you know final outcome.

Removed free play unit from DS100 with selector latch issue and put it in DS160 and it works fine.

Removed free play unit from DS160 with no selector latch issue and put it in DS100 and the selector latch issue is still present.

Soooo, the probllem must be somewhere else, not sure trouble shooting manual is applicable with free play unit installed?

Darrell

Darrell,
OK--that proves it is NOT the credit unit--
Check the "service switch"---the small "sliding" black style switches (if used) often failed as the "internal" spring broke.
If there is no "spring action" use a rubber band to hold it in the "play" position, until either you purchase a new spring, or another type button. Also--the other part of the service switch can fail--not very often, but I have seen this happen--or the connections to the switches, or plug are no longer good---
Hopefully you will see it here--it can also be the latch solenoid itself, has opened--tho I doubt it would with the replacement free play unit attached--

Kudos Ron!

With finger held black slide switch in place and the selector keys latch and make selections as intended!

Thank you so much for freely helping those of us without the vast knowledge you have Have a great day.

Darrell,
Your post is a little confusing ?? I think you are saying the switch was what caused the problem ?
If so, glad to help--if you would like, I would appreciate a contribution of what ever you think the advise was worth, to the "Wounded Warrior Project" ( www.supportwwp.org). Ron Rich

Mark came over last night and we attached his wom to this jukebox. The wom and jukebox both worked great for several selections. Then the jukebox quit responding to the pulse from the wom. When an attempt to make a selection from the jukebox was made, both selector keys stayed in the down position until the free play unit released both selector keys. The mech fails to respond or make any movement.

Would the jones plugs be suspect in this scenario?

Darrell,
Either one of the "wheels"in the stepper is not returning all the way "home" or the NC contacts on one of the timing relays, is not closed. Ron Rich
