Seeburg Ls1 will not index to selected record

my seeburg ls1 console (that sat in a garage for 20 years) will not travel to the selected record. the relay in the Tormant board picks up and the selection momentarily latches so i think that is working. when i flip the switch to credit/scan the player travels the full carriage in both directions and the display lights up showing its position. Where should I start?

Start with the Service Manual, so that someone here can follow what you are calling which part. There is no such thing as a "Tormant board"---are you speaking of the SCC ? And what do you mean "latches"--does it remain energized ? The service switch "mech start" position should start it scanning--twice, prior to stopping-- Ron Rich

the service manual calls the selection unit the "tormat", and the Latch relay i am speaking of is what the manual calls the Latch solenoid. According to the manual when a selection is made this solenoid picks up for a time until the record carriage unit starts to move. My problem is that once a selection is made, the Latch solenoid picksup for a moment, the pricing unit subtracts the play but the carriage wont move. can you help please.

OK--I'll try--look at page 4 of the manual--the "Tormat"(aka TMU) is item 23. I believe you are speaking about item 26, the TES.
If I am correct, the latch bar solenoid ( which is NOT a "relay") is operating as it should. If credits are established, it should be energized, thus causing a selected number, or letter to be held down when pressed. The SECOND button pressed should cause the solenoid to drop out (be de-energized) for a second while the selection is being programmed into the TMU, and re-energize, only if more credits were established. This also "programs" the mechanism motor to run, but only if the "Service switch" is in the "run" (or, aka, "operate") position.
If it is failing at this point, you need to check a few things. 1. Is the service switch in the correct position ? 2. Is the total play counter (item #4) advancing ? 3. If on the service switch assembly the small black "slide switch", located next to the "bat handle" switch has retained it's spring "load" ( they have a habit of breaking the spring). ( the other black slide switch is the "reject" switch, and should have the same spring load)
Let me know what you find-- Ron Rich
