AA batteries will work fine.
If you already have them - you might as well use them.

However they probably will need replacing about every 3-4 years.
(less if they are those really cheap and nasty "no frills" ones from
Sollys)



Or should I just get the "super cap". Would this

It's $7 plus shipping, but I would rather do whatever is best.

Thanks again,

Has it leaked everywhere yet ? This sounds like the original battery
that was supplied new with the machine.


if its 2.4v - you can use 2 AA nicads in series - in most of ours we
just used a "super cap" (ie: 1 farad 5v capacitor that is designed
specifically for this sort of application)

if you use any sort of battery - I would advise strongly that you
mount it outside the case and on leads. This will prevent damage to
the PCB and circuitry when the battery ultimately fails and leaks in
the future

Well, I replaced the battery with a dual AAA battery holder. I
thought it was a AA holder, but it was AAA, still 3V, so should work.
That didn't solve the problems. I do have the older CCC, it has the
two 5101 CMOS chips. So I guess I should replace them next. Any
good placed on the web to buy them from.

Thanks,

Jeremie

Any sort of 1.5v battery is fine (AA,AAA,, C, D etc. you may need 3
of them as this is what is typically used on 5101 systems.
Thanks,

I don't know where you can get the 5101 from. I'm in Australia and
dont know of any sources for these chips any more.

Last lot that I did buy were from www.farnell.com.au some years back
and were $10 US a chip. They have not had them in the catalogue
since.

There must be a place though as these were also used in old pinballs
etc and many other things. Also they are known to fail over years
too.

Would this be it here? It's $4.

So if this is it, I just need to buy 2 of these and replace the 2 on
the board.

That is the right one buy 2 of those and put them in the board
and that should fix it

Are you using rechargable batteries? If not, you need a diode in series
with the batteries or the juke will try to charge them, and that isn't a
good thing.

No, just regular AAA batteries. I knew there would be a catch. Is
there a certain kind of diode I need. This is past the knowledge I
have. Diodes are one directional I take it. Do I wire it on the
postive lead, with the flow going from battery to PCB?

My 5101 CMOS repalcements are on their way.

Jeremie

I have for many years wired AAA batteries in to such circuits without
the diode and it hasn't caused any harm that I can recall - but
technically a diode should be there.


- juke PCB ----II------II--------- + juke pcb
- AAA + diode

Buy a diode. an 1n400x (x=any number from 1 through 7) and wire it
in as shown above.


If you follow the diagram above - the end of the diode with the white
stripe must go to the right !

------II-------stripe is THIS end.




One thing that is MUCH MORE IMPORTANT is NOT to have the batteries
mounted inside the black box near the circuit board. Instead - bring
them out of the box on wires about 12 inch long and then put them in a
small plastic bag and seal it closed with a cable tie etc. This will
prevent battery acid from leaking all over your circuit board and
destroying it in future as the bateries die.

note that they will often leak long before the voltage drops enough to
start causing memory problems.

I am getting ready to place an order with this guy for someone else I
am working on. Would you be so kind as to tell me of a diode he sells
would work for this juke.

Order the 1N4007 @ 5 for $1. Follow the instructions that KLR wrote for
how to install it.
