Schorty,
What do you mean by "wobble plate" . The wobble plate is a metal plate that activate the wobble plate switch after the first selection is made . That wobble plate switch commands the playrelay together with the homeswitch. All these things have nothing to do with the write in procedure.I think that you must clean the wipers and the contact rings of the selector assembly,especi

Hi Claudia,
First question; is the problem of resetting the selectorpins in the "A" or "B" side or both.If the problem is just in one side than check the A-B snap switch (the switch just above the service scan switch).
Don't forget to check the connectors in the controlebox unther the mechanisme. For easyer troobleshooting see attachment.

Oliver,
Is the fuse still blowing after you have disconnect the wobble plate solenoid ? If not, the coil must be chanched.If yes, there is still a short circuit in the -28V.
When you made a selection, in the controlebox is no action,that's only for the mechanisme after you have made a selection and i think that is O.K. because when you made a selection by hand, the mechanisme is working no

Please disconnect the wobble plate coil (1 lead connector) and try again without coil.

Hello Oliver,
Sorry, but i wrote wobble plate "solenoid" ! This solenoid helps to set the first selection . The A-B switches have nothing to do with the selection write - in but with the read - out detection en reset of the selection.
Don't mix a coil with a switch.

Hello Ruha,
This is maybe a usefull tip; If the first and the second digit are lit and the lock bar solenoid is not active, than check the fuses in the metal selectionbox .The lock bar solenoid must be active to lock up the third digit button and command the write in relay.
succes ! Piet

Hello everyone,
I send again with an attachment the situation when you drop in a coin. If you follow the red line from common, than you see that the ground is passing every letter and number switch. When you press the lock bar solenoid by hand,the lock bar hold switch is closed and gives directly ground to the solenoid. In this situation pressing the release switch gives no effect on the lock ba

Hi Rocklitzer,
Try this easy way to localise the problem. Take a lead one side on the ground (common) and touch the other side on the release button switch.With the credit lite "on" and the lock bar solenoid is energized, the problem is in the pushbuttons. No reaction? Touch the lead against the accumulator credit switch. No reaction? Check wiring between solenoid and accumulator ced

Hi Rocklitzer,
When you press the lock bar solenoid by hand, than you are closing the lock bar hold switch and you can press one selection. That lock bar hold switch overide the accumulator credit switch, the release button switch and all push button switches.The problem is most of the time the accumulator credit switch. See attachment for easyer servicing.

Hi Rocklitzer,
In the instruction manual on page 20 you find a picture of the accumulator assembly.Unther the ratchets there are 2 small control switches; 1 for the creditlite and 1 for the lock bar solenoid coil. Your problem is probably there or the release button switsch (near the push buttons). Good luck.

Hi Willi,
Please check IC 701, that's the display controller MM57163N. You can take one of the hit tracker to check that.

Hello Joop,
If there are contacts broken or missing than you have a problem because there are no "spare" contacts. But in general is the problem not so big. Check the moving part unther button "D"or "E"and look for broken contacts. It must be possible with a bit of luck and a lot of patience. Good luck.

Hello Othmar;
Absolute,the correct way to set your Max 477 on "free play" is set dipswitches D1; D2 and D3 Off. To find your problem,switch off the juke box, pull out the white coinswitch connector on the profit setter and switch the juke box on.If the display is normal now, set D1,D2 and D3 on and the creditdisplay must count from 1 to 99 and remains at 99. If not, than there are pr

Hello Achim,
I will give you a few tips to adjust the record magazine. Maybe somebody else will translate it for you.
- The bush of the grey disc on the left side of the magazine is maybe broken. Due to that fact the slot disc is not in accordance with the record magazine.In that case, the grey disc has to be exchanged or better, the bush has to be tight by a garden tube clamp. (approx. 1"

Hello Achim,
Please check the grippermotor. Is the speed and noise "normal". If not - open the motor, clean the collector and check the brushes. If the motor turns normal and the fuse are still broken, did somebody adjustments on the latching relay 301? Don't adjust these contacts to close. This relay is not easy to adjust !
Succes ! regards - Piet

Hello Achim,
The fuse that you need is 500mA slow blow (trage). You will find that type in every electronic shop. Check also R305, this 5 OHM resistor is reducing the speed of the grippermotor when placing the pick-up stylus on the record.See attachment for easyer troubleshooting.

Hello Achim,
On the mechanism power board, that's the board with the two relay's on the back of the mechanism, you will find a 0,5A fuse.That could be the reason for your problem.

Hello to everyone,
I think that there is something broken on the gripperhousing; thats the base where the grippermechanisme is fit on. I think you are missing the stop for the grippershaft. To check that, please do the following steps:remove the grippermotor so that you can turn the grippergear by hand. Remove the two gears on the grippershaft. If you can turn now the grippershaft more than 360°

Hallo everyone,
Maybe i can give you some information. If there is credit on the accumulator, the lock-bar solenoid must be energized. On one side of the lock-bar solenoide is allways power, the other side is ground via a contact in the credibox(unther the accumulator) and -don't forget- the resetswitch. That's the switch next to the pushbuttons. For easyer troubleshooting -see attachm

If there's a loud noise in the controlebox when the record is playing, please check the fuse's on the powersupply, i think it's a 3 Amp. fuse.
