Adjusting the coin grinder

Hi, back home from London and straight into the repair business

The interruption was caused, quite simply (and stupid to have missed it) because the rubber protector had slipped downward.
This happened whilst cleaning the contacts, causing two of the three contacts to make contact between them, hence closing the circuit.

Now, I tried again closing the first relay (the first one in the movie I posted earlier) and again there is that buzzing/clicking sound.
We pinned the sound down to it's origin, which seems to be this counter thingie at the front.



However I'm not sure this is the motor you are talking about.
I'm digging in the manual as I type this to find where the next "hickup" is, and how to get over it...

Hi Nick,
That "thingie" is the "total selections made meter"-NOT a motor, and if you are hearing it "buzz" the pulse it's getting is MUCH too long, which will soon cause it to smoke. When operated correctly, you should hear one, "click" from it--that's all-- Check the Service/parts manuals to locate the motor-- Ron Rich

Sometimes all you need is an extra pair of hands and eyes, thanks to my dad we started measuring all of the points.
We got a high resistance at the copper coils, the black wire, which leads to the fuse. The fuse was new when I inserted
it a few months ago, before I even had the coin unit back, complete with all parts.

Whe opened it, measured the fuse, it was a "1", and compared to a spare new fuse which was "0.02".
We replaced it, and, well, then this happened

in all likelyhood, the fuse blew the first time the system was complete, since the coin grinder was maladjusted.
It's only after a few days I started work on the grinder, but, in the meantime I did learn a lot and the system is now clean
and should be top notch for at least a few months. MANY MANY thanks for your kind help.
If there is anything I can do as a return, do let me know.

Nick.

Hi Nick,
Come on now--you are kidding us -- aren't you ? That's a video of a brand new, WurliTizer 2000, taken in 1957--before you were born !
Looks fantastic !!
One thing I do not quite understand--the fuse fuse size you used, and which position it was in? Do NOT ever use larger size fuses --anywhere--use ONLY size and type as shown in the schematic, or markings on chassis. Ron Rich

Haha, if only HD and iPhones existed in 1958 then I might be lying to you indeed I'm from 1981 by the way.

I bought it from a store called bennies fifties, who sell restored jukeboxes, although mine was (and is) in pretty much the state they bought it in. If you look closely you can clearly see signs of age and usage, but indeed very little. Some "oily" stains around the ABCDE letters, some rust here and there but all in all it's in great shape.

Apart from the coin mechanism/playrak, which I've been restoring since January, piece by piece, and learning about it as well, piece by piece.
Actually one of the first things I bought was a fuse for it, thinking the problem was as simple as a blown fuse. Ironically, that was also the final solution ! There was a fuse inside when I bought it, broken in half and clearly not the correct one.

So after I found the manual online, and coming on this forum, I bought a couple from the only supplier I could find, the mouser electronics website. Full details of what I am using now below. And they seem to do the trick.

I'm now awaiting my order from ebay.com with the 5,10,25 cent coin grinder to complete the jukebox (any day now).
And after that I'll fall into a black hole since there is nothing more to repair.... Never thought I'd enjoy this thing really.

Hi Nick,
The point I was attempting to make, which I am not sure you understand, is that fuses come in many sizes/types, all in the same glass, with two metal ends. I have them in stock from 1/8 amp to 25amps--one MUST look at the fuse end and read what is stamped there, then compare it with what either the schematic says, or what is written next to that fuse holder. Use of a larger size, MAY , or, WILL, cause, HUGE damage, as an "oversize fuse" will not "blow" in time enough to prevent damage !

Ah ok ! now I understand, thank you ! I will have a look tomorrow and see if I need to place an order.

thanks again ! never would've gotten this far without you !

Hi Nick,
Glad I have made it clear for you ! I would advise you not to power up that phono, until you are100 % positive, that all of the fuses are correct -- Ron Rich
