Rockola 470: worked last week, now it won't. Advice?

Hey there:

Got my first jukebox, a Rockola 470, about a month ago, and haven't had any real problems with it until today. Usually, when I turn it on, it powers up in a couple seconds; I had it filled up with 45s and it could play all selections. Today, I turned it on, and the lights wouldn't even come on. Since it was just working when I last used it a few days ago, does anyone have any advice for what I should do to get it working again? Thanks,

Hi ErikB

Check "all" the fuses to see if one of them has blown.

Fuses usally blow for a fault condition.
And if a replacement fuse of the SAME value blows, it's time for some troubleshooting.

I would suggest doing a couple of things here--1.) Check that the installed fuse is the correct type and size for that purpose--usually fuse sizes, types, are marked on chassis -- if not see the schematic. 2.) You look at a "blown fuse", prior to replacing ! If you see a real "black area" DO NOT replace it with anything--this indicates that there is a "short" somewhere, that MUST be found, prior to doing real damages. If you do not see a real black mark, I suggest you replace it with a fuse that is smaller, first. If the smaller fuse holds for a few seconds, you probably had a fuse that was just "worn out", or a momentary short, that has self-corrected ? Ron Rich

Appreciate the advice on fuses (and how to best troubleshoot them)! Are the locations for all the fuses going to be obvious when looking inside the jukebox? Or would a service manual be helpful in locating all the fuses? Thanks,

Hi
They are located externally and internally on the power supply unit, check also the on/off switch at the back, most people power up and down a jukebox using the plug rather than using the switch, just in case it has been switched off.
Not sure if plugs are fused in the USA but i would check this also and also that none of the cables are loose in the plug

Hi Clones,
What ????--you think we are still living in the dark ages, here in the USA ? MOST of the homes here, have circuit breakers, rather then fuses--

Hi Ron
three pin plugs in Ireland and the UK are fused, the fuse is in the plug across the live phase, different fuse rating depending on the appliance, not sure about other locations in Europe, along with circuit breakers and a residual current device breaker which covers i think any imbalance in the live and neutral phases for the sockets in a building, i guess we must be one step ahead except in jukeboxes

Hi Clones,
There is what is loosely called a "National Electrical Code" here, but each little "fiefdom", enhances it. It seems that here, in my city, we are covered by the national code, the state code, the county code, and the city code--and, oh, yea--the fire code. "Fusing" ( or, today CB's) are all installed at the central input service (power) box. They fuse the "hot", or, "live" side. I have seen old fuse boxes that fused both sides. I have never seen anything fused at the plug. Some things sold, are fused at the inside end of the power cord, same as jukes--most items designed for home use, are un-fused. In the last 15 or so years, "Ground fault interrupter circuits" (GFI's) have begun to be retrofitted to outlets where danger of a ground is present. In newer instillation's, this is combined at the service box, with the circuit breaker. Ron Rich
