ami-man's advice on Rowe Ami jukeboxes
Mercuryfox50:
Alan,
Typically, one end of the Red & Black RCA Terminals connects to the Mech Control and the other end connects to the Pre-Amp. For the "Test", I connected one end of the Red & Black RCA Terminals to the Mech Control and the other end to the "Audio In" on my home audio system. After connecting to my home audio system the music continued to cut-out.
I attached images of how the RCA terminals attach to the Mech Control, the Pre-Amp and the Home Receiver (for the test).
Do you believe that if a dry joint (cold joint USA) exists on the power supply PCB I will be able to notice it?
Thanks,
Ben

Hello Ben,
In your earlier post on doing the test to your hifi you said that the music cut out from the start of play? or was it during play like when connected to the amplifier?
What I am getting at is when connected to the hifi are you getting any sound if the input is mismatched you may get very little or no sound. If this was the case I would try connecting it up to the inputs marked DVD in.
With regards to dry joints on the power supply remove the power supply unit from the cabinet and look at the connection pins that go through the PCB for any cracking around the soldered pins both for the output and the connections from the transformer onto the board. Use a magnifier if it helps.
Also look at the the molex plug that plugs into the output from the power supply for any signs of heating of the connections, this would be seen as the plastic of the plug would be discoloured.
you can remove the individual connection pins by pushing in the pawl that locks the connection into the molex.
If you remove the pin look for any tarnish on the pin (clean with a fibreglass pencil or a pencil rubber) and clean the connection face, because the connection is a folded construction, if slightly unfolded it will put more pressure on the connection, remember to raise the pawl so it will lock the connection back in place when re-incerted.
Please let me know what you find, more pictures are welcome.
Regards
Alan

Alan,
The consistency and duration of the music cutout when being played over the home stereo receiver amp vs. the amp on the jukebox was exactly the same. Last night I pulled out the Power Supply PCB and the Pre-Amp/Amp and closely looked over all soldiered joints... everything looked great to the untrained-eye. After putting everything back together I figured that I would run the codes. I was able to pull three codes out of the system: "A WARN 06-01 18" (Start: 17:00 10/28, End: 00:00 00/00); "N WARN 06-02 03 (Start 17:51 10/26, End 15:45 10/27); "A ERR 05-63 20" (Start: 00:17 10/21, End: 00:00 00/00). I do not have the date and time set on my Jukebox so that information is most likely not accurate. I noticed that the third code was "Fatal Error - Mech. to CCC Communication Lost". I check all of the connections and thought it was peculiar how loose the P9 connector (Rowelink) was going into the Mech Control, (picture below) not to mention how far it stuck out. I pulled the connector out, compaired it to how the other connectors went in and noticed that the connector (white plastic piece) was upside down preventing the harness from being inserted completely. The harness has space for 5 pins with the 4th one plugged. What I did was removed the plug from the 4th pin spot, moved it to the 2nd pin spot and reversed all of the wires going into the connector (white plastic piece) and plugged it back into the Mech Control. I fired the jukebox up and it played flawlessly for three songs before I had to turn-in for the night. No idea how the P9 harness got mess up, but now it seems to be fixed. Thanks for your help Alan... you have taught me alot!
On a separate note, none of the animation lights work nor does the lighting in the lower-front panel of the box... any idea what the cause would be?
Thanks!

Hello Ben,
It sounds as if someone had altered the jukebox connection before you got the jukebox.
Well Done for finding the problem.
With regards to The Sound to light, if soume of this is on the then the loom from the Auxillary input/output connection from the pre-amp to the sound to light unit must be good. You will more than likely see two sets of connection from the lights to the sound to light unit. Check the connections like before for dry joints and overheating on the molex connections.
Also in the amplifier compartment is a resister assembly on the back of the compartment that effects the lighting. I would make sure that you have the molex plugs in for these lighting sections, In order to remove the front door section there will be various plus and sockets to check.
Regards

Hello Allan... thank you for your note.
I was able to find an original AMI wallbox transformer on line. I paid $50 for it but it was worth it. Like the rest of the AMI equipment from that era, it's built like a tank!
Anyway, I have successfully connected my WRE to my R-86. The connections are fairly straight-forward:
- left audio
- right audio
- audio common
- Serial cable into CCC unit to pin 3 (logic common) and pin 4 (serial data)
- the two AC power / transformer leads
All connections are clearly marked inside the WRE, so I didn't have to find a manual to make the internal connections.
I've really enjoyed cleaning up the WRE... once all the nicotine was removed it shined up very well.
Let me know if I can return the favor to you sometime. While I don't have alot of experience with the Rowe's, I have had a chance to refurb an R-84, R-86 and most recently the WRE wallbox.
I look forward to talking again....
Regards, John from Washington State.
