SPS-160 Selection Lamps Not Lighting

Another question. The selection lamps on my SPS-160 do not light. I am assuming since my pricing unit does not have a pricing programmer this is the cause. Can anyone confirm?

Thanks,
Kent

Kent,
Answers to both posts--
Yes--you are looking at the correct pages--
What are you terming the "selection lamps" to be ? "Select any single/Album" ? or "Selection now playing"--? Lack of programmer does not affect either.
(Do you have a copy of my "Seeburg Microlog Trouble Shooting Guide"? It would have answered most of your questions--so far-
Contact me off list if you wish to purchase one--at: ronnnrich@yahoo.com ) Ron Rich

Ron,

Sorry. I meant the "Selection Now Playing" lamps at the top of unit. I do have the MicroLog Troubleshooting guide.

Thanks,
Kent

Hi Kent,
The "selection now playing" lamps ( all # 19's) are powered by the 25vac on the terminal strip on the front of the mechanism. On that model, there are three 190 ohm 5w resisters, each one for each digit in the selection number. The 1/2 first digits are controlled by the switch on the left side of the pick-up arm cradle--either one of the two are always made. The other digits are controlled by the location of the wipers under the "Selection Contact Block" which is located on the very top of the mech. If the jukebox was EVER laid on it's back, without being PROPERLY bolted, there is a great chance that these wipers have been bent. The two first digits are plugged into the contact block on the left-top, using a two wire Molex plug. The other digits also plug in there, using a large (33/34 ? pin) Molex plug--use caution on this plug--support the "locked in side" with your other hand when installing/removing it, as it has a tendency to loose it's "locking tab". The service manual has the schematic in it--but bent wipers are the usual problem. One other thing--sometimesthe sockets for the lamps loose the "common". If that's the case, solder a jumper across all un connected "commons". Good luck, Ron Rich

Ron,

First I want to say thanks for all the help. After reviewing the mech schematic you referred to, I quickly found the fuses before the number contacts and the meter solenoid were blown. Yes, I said fuses. Someone thought it would be better to put in two fuses instead of the required 1/2 amp fuse. Click the picture below.

After soldering in only one fuse and the correct fuse, the selection playing lamps are working. Check it out.

Again thanks for all the help.

Kent,
That is not the correct mechanism for that model. It's an earlier version--OK to use, but that circuit was modified so that the fuse was not controlling those lamps. The reason for the two fuses--the guy was just too lazy to remove the blown fuse--I see that all the time-- Ron Rich

Ron,

Thanks.

The SPS160 service manual manual referred me to the USC1 service manual which had the mech schematic. Are you saying this is not correct?

Not sure what you mean by the fuse was not controlling the lamps. I replaced the fuse and the selection playing lamps are now lit and the popularity meter is working. Just a little confused.

Thanks,
Kent

Kent,
Very interesting--do you have a re-print manual, or an original copy ?
I just checked my original, SPS 160 Service Manual, and it is wrong for that circuit also--but there are several other small changes between the USC-1 and later mechs.
See page 13 of my "Trouble Shooting Guide" for further info-- Ron Rich

Ron,

I purchased all of my manuals from Victory Glass. I was wrong about the manual directing me to the USC1 service manual for the mech schematic. The SPS160 service manual has the mech schematic and I have provided a scanned copy of the schematic below.

First, here is a scanned copy of the manual cover.

And now the schematic with the 24vac fused circuit highlighted (I am sure you knew this though).

I read page 13 of your troubleshooting guide, but again, the problem with my "selection now playing" lamps not lighting was solved by replacing the 1/2 amp slo-blo fuse. Could someone have placed an older mech in my juke? Seems like that might be possible since you note they are fairly interchangeable.

BTW - What is the 3M16 switch and where is it located on the schematic? Was it removed? I see 3M15, but no 3M16.

Thanks,
Kent

Kent,
Yes-I have that same page in the original manual--it's wrong for that model--guess we never caught that error--or its possible that there is an "issue 2" of that page, in later manuals ?---3M-16 was located on top of 3M-15-- is there a 3M-16 switch on your mech. ? The 3M-16 was eliminated starting with the USC-2 model.
Yes--someone changed that mechanism--at least the "carriage" portion--as I wrote in the Tbl Guide, the "selection now playing lamps" were un-fused. The fuse only covered the pop meter in all mechs after the USC-2, mid production. Ron Rich

Ron,

I think the 3M16 switch is there, but I'm not for certain. Can you confirm?

Kent,
Nope--not on that one--
Shoot me a pix of the terminal strip on the right side of the mech--

Ron,

Here you go.

Let me know what you think.

Thanks,

Well, it appears to have the modification added--but improperly -- Does the pop meter plug have a diode soldered from on connector to the other ?
Ron Rich

Ron,

Well looky there ... it does ...

Is there any way to tell what model this mech came from? Based on your statements, it is not the mech that came with my jukebox. Does this number imprinted on the mech help?
