Wurlitzer 1015 O.M.T. (88)

Hello I recently was given and 1988 Wurlitzer 1015 One More Time (45) juke. (SN 28099576) When it was given to me, I was told the display did not work at all. Everything else looks BRAND NEW! After tinkering with it for a few days, I re-seated the main power line coming out of the amplifier that goes to the door lights (Just checking to make sure all connections were snug) Since doing so, The juke lets out a very loud, high-pitched squeel as soon as it is powered on. I know that this problem is amplifier-related, but I don't know where to go from here. Ive also had no luck with the display problem, because now I have to power down the juke as soon is I turn it on to avoid damaging any other components because of the high pitched squeal... Any help would be greatly appreciated. Thanks in advance, Alex

Hi Alex,
Moore info needed--which amp ?. Which Sc&C ? 50, or 100,record model ? --still sounds like a poor connection--somewhere--
to me--didja check fuses--power supplies ? Got the Service Manual ?? Ron Rich

Hi,

Check out Flipper's Wurlitzer Troubleshooting page.... towards the bottom.

http://www.flippers.com/wurlitzr.html

I purchased a few non-working OMT's in the past and have found common problems to be a cracked K7 Actuator or a burnt out Carousel light Bulb...

There is a test where you un-plug the bottom left blue plug from the SCC and take a unused jumper wire and jump the green and the blue wire in the plug momentarily to engage the Gripper motor. Each time you do this, the Gripper will either position itself and stop over the player or over the rack.

Get the manual... they are available for free online:


Here is the User Manual for the jukebox… Its 44 pages

Alex, Jeff,
Other then the "flippers page" most of that stuff, listed by Jeff, does not relate to your phonograph--
Ron Rich

Ron....
Not sure what your trying to say.... "most of that stuff, listed by Jeff, does not relate to your phonograph".... I beg to differ....

The K7 actuator is the same exact one used from a 1987 OMT 45 to a 2000 OMT CD 100 with the exception of the color... it was white and is now black.

I have used that wire test on a 1987 45 RPM with lights instead of bubble tubes, as well as a 1989 OMT 45 RPM and a 2000 OMT CD 100. Same results....

As far as the manuals, Much of the SCC programming is the same thru todays machines.... Last date of manufacturing Sept 2013.

I certainly do not have the experience that you have.... And I tend to lean towards my 1950's Seeburgs, with that said, Everything I stated above is true and based on my own personal experiences... I' have definitely had that Amp pop sound on turn on with no lights on the display and it turned out to be a faulty K7 actuator... Had I not seen the crack I would have never thought that the K7 was the problem because all online info states you should have a 8 in the display when the K7 is faulty. Well my K7 was cracked, everything was out of alignment and the juke thought that a CD was loaded.... Hence the pop of the amp... After putting in a new K7 actuator, resetting the gripper arm a few times, the display came back and all was well.

Find the K7 actuator and see if it is loose by moving it up with your finger.... If you can move it more than a little with no resistance its probably cracked... Look for a visible crack just above the internal nut.

Here is another manual that is of a little older date that you could use as well"

sorry for leaving out such important info.... from looking inside the juke, I believe the S&CC is model 100-16-200 (part number 40312). Also it is a 50 record model and the amplifier part number is 40 200 000 00 . hope this is the correct info needed

Guy's,
I have at least 4 different "versions" of the "OMT Manuals"--and there ARE differences !--Yes "K-7" is the same, and I have seen "a million" broken ones ( I usually "fixit" with a hose clamp--I use a small hose clamp to actuate the switch,after sliding the plastic original out of the way)
For this model, I suggest the "original", earliest version, Service Manual, is best--, as it has the first version amp, and S&CC.
Ron Rich

All fuses checked good and k-7 switch is secure and in tact. doesn't move at all with push of a finger
-Alex

Alex,
It is NOT the switch--it is the switch actuator, that comes loose--( I have also seen "bad crimps" at the fastoon going to that switch--violet wire)
Ron Rich

checked the k7 actuator out... all looks good. ive figured out a few things. ive removed the output speaker plug from the amplifier and the loud squeal I was talking about in previous posts goes away. with that being said, I can now try to address the display problem. when I turn the juke on, I get nothing from my display. my front door lights and bubblers work though. there are no lights on on the S&cc, but a green and red light are on on the amplifier . when I press the coin switch as if a quarter were passing through, I get a red light beneath the letter M on the S&CC which tells me the computer is getting power... any further ideas?

ive also just realized something else. Fuse "Si-5" is blowing. I realized it was blown and replaced it twice and it blows upon power up each time.
thanks
-Alex

Based on one of my older owners manual that I have for Selection & Credit Computer 40313 I have read the following:

Fuse Si 5: 12 V positive supply (SCC-Unit).
Symptoms if blown: S & CC-computer dead.
(except red LED-M still lighting up on coin insertion).

IF--and this is a VERY BIG "IF"--my memory serves me, the size of that fuse was increased, as they found it was "blowing for no good reason"--check at flippers for the correct size, don't go by the silk-screen markings--seems that they used a type written "sticker" with the new size on it--'course, it's fallen off by now !

Here is some good troubleshooting documentation that you can use for your year machine:

Great thanks for the info... the only question I have is my specific model juke is a 45 model, not a CD model. Are these models the same besides the player? Since ive last posted, ive found that fuse "Si-5" does NOT blow if I unplug the harness that leads to the player from the amplifier. to me, this signifies a possible player problem?
