I have an LS1 that is blowing the circuit breaker in my garage as soon as you power it on. I assume it's a short somewhere but I'm not sure where to start. Just learning these systems.

This can be a dangerous situation and a shock hazard. At this point the only responsible advice for me to give is to "get a manual" www.alwaysjukin.com/items/service-manuals/seeburg-service-manuals/list.htmIf you want to find out what is causing this problem, place a decent sized light bulb in series with the jukebox power cord. I'd use at least 150 watt. If a true short exists the bulb will glow full brightness. Open the machine, locate the power junction box and start removing plugs. When you light goes out this will indicate the section to look into. keep in-mind that there is already a fuse in that junction box and that it is possible that the power cord itself is causing the problem. Those cords take a LOT of abuse in commercial service. Eventually they get crushed one too many times. This machine is now 50 years old. Plan on a fair amount of rebuilding work on the amp and control unit. The good news is that these solid-state units were wonderfully simple in terms of circuit architecture and parts count. Doing it right also involves major disassembly, washing of all components including mechanism, cabinet and electronics. Note that electronic units must be carefully washed and thoroughly dried before power-up. Rob-NYC |

I had this problem on one of my jukeboxes.
What I found was that the "unfused" jack in the power junction box was broken and the two wires attached to it were touching each other causing a hard short. I didn't find this until I unbolted the box from the floor and looked at the back side of it.
There are some splices in the wiring between where the power cord enters the cabinet and the power junction box, I believe power is split off for the cabinet lighting.
You probably have something stupid/obvious going on (bad line cord, wires pulled out of a splice and touching the cabinet, mouse chewed wires touching each other, shorted ballast, etc.) that you can find by a quick visual inspection of the power supply wiring...you just need to know where to look.
This would also be a good time to check the fuse in the junction box and make sure it is the proper value...the manual is your friend for the fuse and power input wiring details.
Good luck and let us know what you find.

The lighting circuit starting in Seeburgs, from at least the model A on, is always fused-- unless plugged into the "Service Outlet", which is NOT fused ! I would use Rob's method (above) in reverse--un-plug everything, plug in one AC cap at a time --the one that lights the lamp is where the problem is--Ron Rich

Ron,I have a better chance of seeing the culprit if it can remain constant till I touch what caused it. Disturbing things can cause it to clear and I'm then left concerned that it will re-occur...as soon as I get home and make other plans....

Thanks for all the help. This was one of the first units I worked on and was still very lost. Now I just don't know where I am. It ended up being a back toggle switch. I replaced it with a $5.00 SPST from Ace and the problem was fixed. Thanks again for all the help.
