HOW TO PUT-BO/AC equipped WurliTzers on "free play"

[Ron Rich]

Easy--

Just jump pins 2,6,7 & 8, TOGETHER, on the SOCKET, for the BO/AC, on the control box.

EDIT; plug for the BO/AC needs to be left out when control box is jumped !

How do I know which pins are 2,6,7 and 8. Also could I setup a switch to turn off free play once songs are entered into memory

[Ron Rich]

Easy--you READ the numbers embossed on both the plastic plug & socket. I GUESS, you could switch the jumpers open to remove free play--but why?
You do understand that the plug for the BO/AC needs to be removed from the socket, when the socket is jumped. While on the subject--PLEASE read, and comply with, the posting "rules" in the introduction section of the forum. Ron Rich Board Monitor.

Hey Ron

Reading your post on jumping out my BO/AC equipped jukebox. I see that you say to I jump pin #2 to 6 and then pin 7 to 8 I have a wurlitzer 2800 americana. On my BO/AC plug i do not have pin receivers on # 7 and 8 (although there are pins on the plug at those locations) why would they wire plug at those locations? With that said do you know what pin locations I should jump out? The plug is numbered from left to right starting on top 1,2,3, second row 4,5,6 ect for 5 rows with pin receivers located at 2,3,6,9,10,12,13,15

Thanks
Kevin

Kevin,
If you have a "2800" phonograph, you do NOT have a "BO/AC" in that phono ! Read the other sticky --- Ron Rich

Ron
Sorry thats a typo its a 3800

OK--that makes more sense !
Just insert jumpers into the (Molex) SOCKETS for the BO/AC. Leave the PLUG hang--

Not totally understanding where to put the jumpers. Dont they have to be be put in certain positions? like 2 to 6 and 13 to 15 or whatever? Wont it do damageif they are jumped out
wrong?

Kevin,
Don't know what you don't understand ??---PURCHASE, steal (from an unused plug), the correct Molex pins, run a wire ("jump wire") into socket pin # 2, with a wire attached, then run that same wire, with pins, to sockets #6,#7,and #8. Ron Rich

Ron

but as i stated earlier there are no sockets in #7 Or # 8 I totally get attaching a jumper from 2 to 6 and then what? As you might imagine I dont want to short out the components by jumping the wrong pins
 
There are sockets only at the following #s 2,3,6,9,10,12,13,15

Kevin,
I dono--I've jumped lotza them--never seen one that had those pins empty-- Look at the schematic for that model ? You will need to ground the key switch and the lamp (if you want it to light). Just Guessing--does that model not have an album select lamp ? If not just jumping the first two, may do it. Are you sure you are looking at the correct socket holes ?? The numbers ARE "embossed" on it ! Ron Rich

Ron,

You might find this interesting. I went back to plug and socket and verified the numbers that were embossed on the plug all of which were in the locations I previously stated.

There are sockets only at the following #s 2,3,6,9,10,12,13,15 Any missing number does not have a socket in that spot. On the plug itself the plug has wires with pins at 2,3,4,5,6,7,8,9,10,12,13,15 which means at 4,5,7,8 have pins with wiring that have no connection in the socket.
SO I took your advice and looked at the schematics and it showed the socket part of the molex reflects the 1,4,5,7,8,11,14 spots are empty on the schematic, but the plug schematic shows the following.

1.
2. ground to bonus accumulator
3. cancel single
4. cancel lp
5. cancel pre - sel program
6. single credit
7. lp credit
8. rpe -sel credit
9. add more coins light
10. clear voltage
11.
12. + 12v
13. computor inhibit
14.
15. - 15v

any suggestions? Do you still think jumping just 2 and 6 might put it into free play


Thanks Kevin

Kevin,
Try it and see ?? Ron Rich

[knyli57]

Thanks Ron

Once it warms up here ill get a chance to go into garage and see if that works.

On a separate issue, the juke box suddenly started playing the 45's at a slower speed any suggestions on what might cause that to happen? They play but not at the proper speed

Hi Kevin,
Has this phono got an "intermix kit" on it-- sounds as if maybe it's stuck on 33-1/3 rpm ??
