Seburg M100C problems

I recently acquired a Seburg M100C that continuously selects a record with out playing it just returns it and goes on to select another one. The coin operator has been removed years ago. The selection buttons do nothing at this time however when power is applied and you select a button it does lock down and then release when the second one is selected. If you hold the momentary service switch down it will then play a record but will not reject it. I have not gotten a service manual yet however one is on the way.
Any info you can give me would be helpful.

Thanks

JBR,
I strongly suggest you wait for the manual--read it, so you can use the terms in the manual too describe the problems. so someone has a "fighting chance" to help you---

I will wait for the manual
Thanks JBR

I received the manual and have made some headway with the m100c
I found that the trip switch is shorted resulting in the continuous select w/o playing the records. However the unit now plays all records w/o making any selection it does this with the 27 pin plug to the selector assembly unplugged also with the 8 pin plug from the electrical selector unplugged from the cancel & credit unit.

I believe that Electrical Selector and the and the Credit & Cancel units are working because credits can be established by using the credit button, the select light comes on and when you push the selection buttons they appear to work correctly and the credits are canceled as I think they should when the cancel solenoid operates turning the cam and the select light goes out. The only relay I seen operate on the Step Switch & Relay Assembly is the Play Control Relay. I also have checked the voltages for the units and they all seem to be correct.

This jukebox has been in a home for many years and I suspect that is how they wanted it to play. I have not found any obvious modifications to the wiring or switches that may be the cause.

Any help you may be able to lend would be great
Thanks

Hi JBR,
IMHO, a copy of my "Seeburg Mechanism Guide", would help you greatly, in understanding what is happening on your phono (contact me off list to purchase, if you wish). I am unclear as to the exact problem from what you describe. From what I now understand, either the SA Unit "pins" are not being "canceled", or the mech is operating correctly, and someone has "pulled" a flock of "pins".
Take a look at the pins, "play position" is "out". Push all pins "in", and see what happens---

Hi Ron
After working more on my M100C I now have it selecting properly however it still does not cancel the selection after playing it. It does not cancel on either the A or B side, the solenoid that I can get to appears to be free, also the Popularity meter does not work either, I can see a small amount of movement in the solenoid as the needle sets down on the record but is not enough the advance the meter. This solenoid also appears to be free as you can push on it and it will advance the meter manually and does not require much force to activate the meter. I believe that the 25 volt source is there as it appears to be the same source for Selection Assembly and the fact that there is some movement in the meter solenoid. If I am following the schematic correctly it appears that the ground side it used to complete the circuit to activate the cancel solenoids is the correct? I have gone through the gaps and cleaned the contacts on the Cam & Clutch switch and they appear to be correct also. Any ideas you may have would be appreciated.

Also you spoke of your manual in the last post does this cover removing an working on the Tormat Assembly as the manual I have does not seem to have much on that part. What is your email address or web site to get one?

Thank
JBR

Hi JBR,
If you see any movement in the pop meter section, your problem is the adjustment of the "C" -"S/C" contacts.
Either the contact points are "dirty", "pitted", "burned" or are so worn down that here is no silver left, or just out of adjustment.
My Mechanism Guide does NOT cover the SA Unit, or Tormat, as I consider those to be part of the "selection system" There is a "electronic overview/sequence of operation" only-- to do so would have run costs up too high on the book.
PM me, or see the"announcements section", above for purchasing info.

I have been busy with other projects however I have made some additional headway with my M100C as you suggested in your post I went through the switches again and did find that the C and SC contacts were not making and breaking at the proper time so with adjustments again I got the B side of the cancel circuit and the popularity meter to work correctly and found that the A side had a burned coil which I have replaced so all is working quite well now. I just wanted to thank you for your help and say that this forum is a wonderful place for help with problems.

I have an additional question, the animation motor runs but needs to be serviced what weight oil is to be used in the transmission and how much.

Thanks Again JBR

Hi JBR,
Glad you got-it ! 20 wt. ND oil--same as the mechanism---

Ron
Thanks for the infromation, however the other part of my question is how full do you fill transmission reservoir?

Thanks JBR

JBR,
There were a couple, or more manufactures, that supplied Seeburg motors, in those days--IF, you have the style with the "reservoir", there will be a screw in the "oil hole"--otherwise, you must dis-assemble and grease the gears-- Ron Rich
