Looking for help on a seeburg LPC 480 Wont play A or B side

 it  will select  scan and pick up the record and turn table stops

  i did notice the play meter coil stays energized .

   clutch appears to be moving ok from inspecting  the plunger from rear of jukebox

If the play meter coil is staying energized, you soon will have a fire !!! Turn the phono off till it's fixed !!
Possible that the subtract coil in the APU-2 is also remaining energized--but that should "blow" the 1 -6/10 fuse ??
That coil is operated by a switch in the APU-2. Do you have a Service Manual ? If so, read the switch info, if not, it MAY be shown on the sticker on the APU. Ron Rich

cam switch contacts P O has me confused
O controlling motor cap &
P - power relay coil and that energize and relay contactsthat  seem to be ok - motor is not turning turn table -it will scan fine

id like to signal trace power to motor in play mode

guessing my problem is in the 25volt motor control circuit

Please READ the Service Manual, and use the terms they used in it. Please also read the PM I sent you, and the "stickies" on top of this post.
When you say "play meter coil"--what exactly are you talking about --the total play meter, or the "popularity meter" ?
If your motor "dies" upon pick up of a 45 rpm record--slightly pull back on the record clamp arm--If it starts the motor then, you ether havea bad 45 TASU-1, or a motor/drive train, "gummed" up. If the 45TASU-1 relay energizes, the problem is not in the 25 volt circuit. Ron Rich
