SPS160 selects record, needle contacts, and then stops

[rhetr0]

hey y'all. noob here.
I had a tech coming to the house to fix my 1972 160. but it looks like his website doesn't feature Jukebox repairs anymore. I'm still waiting to hear back. But i might be on my own. I have the factory trouble shooting guide, and am trying to figure out why the record was selected, picked up, and began to turn long enough to hear the initial clicks and pops before the motor just stopped. 
I don't see anything in the guide that addresses this directly. it does have a solution for PICKS UP WRONG SELECTIONS which is WAS doing on occasion, so i'm wondering if that's somehow related ? 
ADDENDUM
I just found the service order for when my tech came out (about a year ago)
According to my service order it looks like he replaced the A3100 Scan Control Board, and the repaired the DCC3 unit. 
it looks like it did the exact same thing from what i can tell. This happened at selection 179 ; all the way on the right side of the jukebox.
if it's a repeat of the initial problem, i would guess the repair didn't last, and that I should start there:
A3100 or the DCC3 unit?

what a pain. but...that's why i'm here. 
thanks

So the motor is stopped with the needle on the record?

It's currently stopped at selection 179?

Is the 'subtract solenoid' in the DCC staying energized?

Is the repair man going to show up?

Hey Marty!
I'll give you 3 out of 4 (lol)

1) motor stopped with needle on record
2) stopped at selection 179
3) ? don't know how to determine this
4) He's going to show up -thank God

When pressing the cancel knob, will the record be returned to the magazin?
One idea: A bad motor run capacitor (can capacitor at the carriage with two values).

[rhetro]

Hey Hildegard,
No. it doesn't do anything. I tried the cancel buttons but nothing.

did you mean check the voltage of the capacitor at the carriage ? it's moved all the way over to the right side. It's obstructed and there's no way to move it to the left side where I can get access to it (i guess it's stuck). my tech freed it somehow when he was here the last time, but i'm apprehensive about forcing it. i honestly don't know how he did it. still waiting for him.

ADDENDUM:
Ok, reading up on Ron Rich's discussion on the Run Capacitors. 
Thanks

[Hildegard]

Yes, right, I meant the can capcitor at the carriage. If I know right if one section (one of the values) is faulty, then there will be faults like picking up the record bit then stops.
If the record is on the turntable (in playing postion), then of course the carriage cannot move at all.

Can you move the tonearm slightly inwards and if so, does it return the record?
Some years ago Tony Miller wrote "Cannot reject record, either automatically when it finishes, from the switch on the back of the cabinet, or from the optional (P)RVC.": seeburghistory.jukeboxhistory.info/symptom_4.html

Another guess - what happens if the clutch did break? The clutch is needed to get always the needed turn (direction) of the motor (scanning, picking up record, playing record, returning, scanning again). If the clutch breaks the motor can't turn into the needed direction.

I wondered, since it was at selection 179 (if that is significant?), whether the reversing switch had partially operated removing power from the motor? Something else to throw into the mix but nice and easy to check! Although if that was the case, you might not have expected it to load the record?

Hey guys.
It would reverse when it hit the end and just scan the other direction. And you could NOT play selection 279 no matter what. so i'm thinking there's something going on there; a bad contact? the reject switch would not work either when engaged where it did in the past -if it picked and played a wrong selection (which it did on occasion). The record is stuck so i can't move the tone arm without scratching the record as well as the carriage in the playing position. my tech somehow freed it but i have no idea how he did this.
he finally got back to me and will be visiting later on this week.

i was hoping the service manual would be a little more informative, but i'm guessing they were made for techs who were already trained to service these things, and these manuals were used to as a reference for ordering part numbers.

[armandh]

is it by any chance a 33.3 RPM record with a failed auto-speed unit?

[rhetro]

Hey Armandh,
no, it's a 45 for sure.

my tech came by today and fixed after 2 hours of troubleshooting.

There are a couple of metal slides held down by 2 hex nuts in the base assembly. One of them needed adjustment to the right (facing the jukebox) that allowed the carriage full travel. i'm looking at the parts catalog and it doesn't have a name for it; but that's what got adjusted.

the bad news is that he's officially done with repairing jukeboxes so i'm on my own from here on out. I have the official Seeburg Installation and Operation Manual & Service Manual, but he said it's not really what the techs use. He had something with him that was more thorough.

He told me to look into Victory Glass.com for replacement parts. I also bought his remaining stash of parts that he was going to just put on eBay:

1 digital control center
1 high power amplifier
1 grey box
1 black box

coincidentally, i'm having a workhop/bench built in my garage to handle such projects (so i'm not cluttering up my kitchen table).

it's running great right now -but it will no doubt hick-up in the future.

I have a lot of studying to do
