I picked up a rescue seeburg ls1. I’m going to give it to a family member once it’s functional, not restored. It’s doing the scan twice not play problem. After spending some time with no success on it I realized I never have put money in it. These didn’t have free free play like the black boxes. So my question is this....
What modifications should I be looking for to stop this? I read that this usually done by keeping the solenoids charged in such a way that it could pose a possible hazard but I haven’t found how this was accomplished. I’ve checked the wiring and I haven’t noticed anything obvious. Once I can undo the mods I will recap the controller and go from there.

I don't understand what you are axking-- Up till the MicroLog models, Seeburgs had no "free Play functions", unless "jury rigged", which, IMHO, ain't a good idea for "fire reasons" as you stated. To set it on free play, my recommendation is to purchase an electronic free play replacement pricing unit( yep--I sell them--contact me off forum). As for the "scans twice" problem--same procedure for all Seeburgs--separate the system--read-out, or write-in problems (or both !) ? Ron Rich

Ron, it's already on free play. I'm trying to figure out how to undo that or at least see if it has a "Ron" approved pricing unit on it. Either way I'm not sure what I'm looking for. If it's jury rigged what would I be looking for to undo it? If it has an electronic pricing unit already in it that is safe to use, what does it look like?

Well,
You got the Service Manual ? Which Pricing Unit is in it ?--which SCC ? Ron Rich

Check inside the pricing unit and see if credits subtract when a selection is made. If not, a previous owner may have removed a part. A credit or credits were added, and since it can't subtract them, it continues to think it has credit available, and also keep the latch bar solenoid on.

My Seeburg Electra was set to free play, however a previous owner removed the latch bar solenoid all together. This works fine, only thing you have to do is hold the first button down while you push the second button.

Hi Lincoln,
Depending on "how" the previous owner modified the UDPU-4, it may "work fine", for awhile, till the UDPU-4 dis-integrates itself !

Ron,
It's been a long time since I looked inside the pricing unit, but if I remember right the only thin done inside was removal of the lever that engages the wheel to subtract credits. Acording to the previous owners, is has been this way since 1980 when they got it. I have gathered all the parts to put it back on coins, so it's on my list of things to do.

Hi Lincoln,
Yep--attsa what most persons did--IMHO, egg-zact-lee the wrong thing to do, as the UDPU beats the "stuffing" out of itself, at the junction of the solenoid and sub arm. Besides this causes the latch bar solenoid in the TES, to be energized continuously, which is a fire hazard !! Ron Rich

Ron, just got back to look at this today. It is a SCC7 Code A (SN#8033) with UPDU6 Code 8282 (SN#082). I was testing the voltages today and it started popping resistors or diodes, haven't look at the schematics to determine yet. After I did that I found that someone has added a fuse holder and when the unit was moved just enough it shorted out on a resistor next to it. So I have some issues to work through on that but I'd still like to figure out how it is on "freeplay" so I can disable that. I did notice that there is a large hum coming from behind the turntable with the album covers on it. That hum goes away for a second after making a selection. It goes away completely if I disconnect the harness coming from the coin mechanism which tells me something is getting continuously charged.

Hi Lincoln,
Can't help on the SCC--just need to replace what ever you burned up and insulate that fuse holder-- the fuse was orinally a GJV type.
On the UDPU--It's either a code A,B, or C, (the "8" is probably a "B") none of which maters, in this case--just need to look at it, and compare it to the parts manual. Find/replace whatever is missing, AND carefully adjust the subtract arm/ and sub solenoid per specs, in the Service Manual. !
Yep--the "hum" is the latch bar solenoid telling you it's getting old and has been energized way too long--
If you read the schematic, you will find out why the hum stops when you dis-connect the coin switch plug.
