Repair help Seeburg DS100H

Ron, You are very perceptive, I took note of your "IF an ONLY IF"! I have now played every selection and a pattern seems to have emerged. The A6, C6, E6, G6 and J6 selection numbers will scan twice and park, but a record is never picked up or played in those 5 positions.

Should I still try the eraser fix you suggested on the A6, C6, E6, G6 and J6 rivets or is there some other problem I should be looking into?

The closest thing I can find in the Trouble Shooting Guide is on page 334 - G - 3, except mine does play B6 and H6, so the "complete number or complete letter" situation is not techinically correct in my situation.

No--just been working on them a long time---
I would suspect that the contact pins that ride on the rivets have been "dished out". If that's the case, take a file and make them flat on top again--be SURE silver is still there--if not replace them, or add silver-- You might also look at the detent switch contacts and adjustment--same story on the points-- Ron Rich

I believe our conversation is about the bottom of the Tormat Memory Unit at the back of the Select-O-Matic unit. I can not find much about this item in the manual I have. I also see a device that has 4 rivet like pins that apparently touch the raised nodes on the bottom of the Tormat Memory Unit and these are the pins that I would need to carefully file flat if they in fact are dished out.

I cnannot locate in the manual what the settings between the Tormat Memory Unit and the rivets should be after making necessary filings to the rivets?

You also mentined some points to adjust and I am unsure which points you are referring to?

I also have a can on "Control Contact Cleaner and Lubricant" from Radio Shack it states it is for Cleaning and lubricating contacts and controls - For electro-mechanical devices-especially drum type TV tuners - Reduces wear - Safe on most plastics Would it be OK to use this on the raised nodes on the bottom of the Tormat Memory Unit and the rivets also?

Which "manual" do you have ?
I would not use that, or any other contact cleaner there. Most products of that type are for such things as "wiping" type contacts (think volume controls).

The cover Title is "Seeburg Models DS 160 DS 100 Servive Parts & Troubleshooting Manual" and on page 32 I believe we are talking about the "Ground Contact Bar" and the "Contact Plunger Assembly".

As I understand what I should do I will remove the Contact Plunger Assembly and inspect the contact pins, if they are dished out I will file them flat. I do not see any guide for reattaching the contact plunger to the ground contact bar, so do I just visually watch to see that the contact pins just meet the flat surface of the contact bar, thus allowing them to ride over the rivets or is there some specified setting between the contact pin and the contact bar?

Should the silver (be SURE silver is still there--if not replace them, or add silver) I am looking for be on the contact pin or on the rivet?

Also not sure what detent switch contacts and adjustment or points you are talking about. Could you splease teer me in the right direction? Thank you for your patience and assistance for this newbie that has many things to learn.

The alignment procedure, and the detent switch, are covered in the Service Manual. Go to the "mechanism" section.
The silver is on the pins--the Tormat rivets are (or should be still) gold flashed. The "grounding bar" is silver plated. If bad, it must be "turned over" and new mtg holes drilled. BTW--most of the above is covered in my "Seeburg Mechanism Guide" (contact me off list if you wish to purchase a copy).

Found the alignment procedure for the contact plunger block on pages 2445 & 2446 of Mechanism section of manual, slill searching for the detent switch and points you mentioned. I am sure you are not talking about the clutch detent. Detent is defined as a mechanism that temporarily keeps one part in a certain position relative to that of another, and can be released by applying force to one of the parts. By detent switch, are you referring to the latching mechanism on the number and letter push buttons?

My Tormat rivets appear to still be gold flashed.You said: "The "grounding bar" is silver plated. If bad, it must be "turned over" and new mtg holes drilled." I do not know if mine is bad (what would symptom be if bad?) but, mine is oxidized (looks like rust) on the flat service where the rivets are touched by the contact pins of the plunger block.

If you have "rust" on the grounding bar where the pins ride--it's bad--
Detent switch adjustments are in the mechanism section of the manual--detent switch is wired in series with the plungers that ride the TMU.

On page 2462 Of the Manual reference is made to a Detent Switch and Contact Gap and Pressue Adjustments, is this the Detent Switch and (points) Contact Gap you made reference to?

Yep--a "detent switch" is a "detent switch"--- Ron Rich

Ron,
Filed plunger contact pins flat, silver still there made all adjustments per your instrctions and I still have the same problem with A6, C6, E6, G6 and J6 not playing while all other selections do work properly? Any other ideas what I might try?

Thank you

Well,
Do you know how to "select all" using a D Cell---if so try that and see if your problem is in the read out or write in section. If in the write in, would suspect a TES contact is bad--but I would suspect that it is missing more selections then you say, at the moment--- Ron Rich

Yes, I have seen that procedure as explained on page 346 of Trouble Shooting Guide.

Yesterday I manual selected each letter and numer and carefully copied down only the selections that did not play.

I will try the flashlight battery test first and also repeat each letter and number sequence to double check which positions do or do not play.

Could you advise what voltage test lamp a person would use to perform G TEST (Write In) on page 347 of manual? I do not have a Seeburg test lamp and I do not see a specs for this in the manual?

Results of battery test are: It started playing songs at D3 and played all odd numbered songs up to J9 and then started playing all even numbered songs from J0 through J8 it then scanned and quit playing any further records. I manually selected all the remaining letter and number selections from J8 though D1 to complete the entire cycle. The only slot that refused to play manuall was A6.

As it played two consecutive records I presume I move on to TEST G, unless this information suggests some other action to you?

Thank you

The test lamp consists of a 33k 1/2 w in series with a NE51H-
Not sure what happened here ? What happened with the D cell check- Where did you "start" the mech. Try this--
Start by selecting B-2. While playing B-2, charge the Tormat with a KNOWN GOOD, D cell. After doing that, reject the selections all the way through the "A" section, and let me know what happens--
