Folks,
Need some help. I have a rebuilt SS160 that is burning through control centers. Here is where I am:
Rebuilt control center (4x) Rebuilt selector switches Rebuilt mechanism Partial amp rebuild. autospeed rebuild credit unit gone thru
--- The control center-mounted diodes heat up and eventually blow fuses. It takes many hours but if it is left on it will heat up and blow a fuse. --- I took the amp, control center, mechanism, switch, autospeed, credit unit and set them up on a wood table and let them sit for days powered on and they did not heat up. They were not touching each other --- When installed - it takes a few days of 8 hours of idle sitting for it to eventually give up the ghost. --- I have been through every component in that control center. They are all 100% --- Unit is grounded. All grounds are good. --- It appears to be one diode that gets hot.
I am on my 4th control center rebuild and I can't take no more.
Thoughts? Anyone ever encounter this before? I plan to put this on my website once I figure it out.
Thanks! -Matt H. |

Matt, that is a new new one, at least to me.
Which fuse is blowing?
F3101: 15 amp for the low AC 25 v.
F3102: 1/8th amp Write-in & Read Out high voltage source.
F3103: 1.5 amp Low DC for coils.

Matt,
As Rob wrote-- WHICH fuse--what value fuse are you using, as a replacement?
Also, Which CODE is that SCC-3 ? Ron Rich

Long story but here is the short:
15 amp the second time. When it blew that 15 amp it took out the transformer in the control center. Melted all of the oil/grease all over the floor.
I put a 4 amp fuse in the sockets mounted to the floor of the jukebox. It is now blowing those fuses. When it blows a fuse it usually takes out the diode mounted to the control center - the one most forward in the control center. It also heats us the resistors in that circuitry.
I seem to have no issue at all with it working. It just heats up over time, causes something to fail and blows a fuse.
It ran cool for a full week sitting on a workbench but when installed it heats up. The only thing I can think of is that there is a grounding issue or a short in one of the components and when they touch each other there is a short. Also there may be an issue with the ground in the house?? Could that cause a problem like this? Voltage on the ground? I do not get shocked when I touch it but then again I am on a wood floor.
One other thought - it works on quarters. I wonder if the customer is leaving a credit and the solenoid is drawing too much over time?
Just trying to pick the brains of the experts. I may just need to go get the parts and assemble them on the workbench and connect them electrically and eliminate one by one.
It is the SCC3 Code C. The pink one.
uggg.... -Matt H.

Matt,
"--4 amp --fuses mounted on the floor---" ?
Do you have a schematic ? Any code will work--there should never be a fuse that large in that SCC. -- READ the schematic, install the correct type/values and reduce the 15 a to a 7.5 or less. See what blows, and figure out why--most USUAL cause is a shorted latch bar solenoid, or total play meter. Ron Rich

Ron,
Yes - read the manual. I am sorry - I am working from memory - the unit is at customer home now. Your suggestion of play counter might be a good one. Not sure why it would be ok out of the jukebox but not ok in the jukebox.
I will email back with some pics once I get out there to pull them and bring them back.
Thanks again, -Matt H. |
