Norman,
Look at the schematic--build a replacement coin grinder, that eliminates the need for coins--I have built a few in the past--only problem you need to compensate for is "button timing". If a button "sticks", or is held down too long ==pop= goes that selection coil ( fused a 3/4 amp !).

Ron has said it right. The most important parts of the system are the solenoid, which in the grinder, subtract a credit and allow a momentary overlap between making the connection at the button, and subtracting a credit. You can build one, using an old solenoid, a relay and a set of contacts (or a micro-switch). Just duplicate what the schematic shows.
This method will eliminate the possibility of frying selection coils, and will not create the annoying buzz that simpler free-play plugs would cause.

Thank you Ron and Startgroove The grinder is in place and it works ok. I looked at the schematic and it appears if i short out pin 1 and pin 8 of the plug that goes from the grinder to the junction box that will give me free play Just as if there are multible credits established. thanks Norman

Since you have a grinder in place, you can modify it for free play in a several ways. All of these changes can be put back to original configuration at will without permanent modification to anything.
If you remove the side cover of the side which it mounts to the board, you will expose the accumulator and the cancel solenoid, along with a bakelite housed switch. That switch is the credit switch and when active applies power to the selector button circuit. There are two screws holding it down. If you remove the screw that is furthest away from the cancel solenoid, and rotate the switch a few degrees clockwise, then the system will have perpetual freeplays. If ever you want to make it coin operated again, simply rotate the switch back to the normally mounted position and carefully (without excessive force) tighten the screw back into place.
Alternately, and a bit more complicated, is to remove both the star wheels on the accumulator. Keep the parts on hand for future use.
Yet another way is to wire the finger (the one which is attached to the outer end of the solenoid rod) to the nearby post (which is at the outer end of the solenoid rod). Wire it with fine enough, and strong enough wire, to keep the finger from engaging the subtraction star wheel, and so it does not interfere with the free operation of the solenoid rod.

I am so glad I found this post! I have Wurlitzer 1100. it does have coin grinder and a coin mech but usually the coins get jammed in the coin mech/slug rejector. does not line up right with grinder or the coin chute. because the coin mech is not correct one. ANyway, about 25 years ago i put on a credit button on the back door which worked fine but every time some one comes over i have to tell them where it is so they can play it. So glad I came across the above about how to free play it with the coin grinder. i did option 3, used 2 small wire/zip ties to hold the dog(finger as referenced above) up and out of the way to prevent it from removing a credit. i was careful not to wrap the tie around the spring on the back that pulls on the dog/finger. works nice. solenoid work just as before etc. I do have one question though. their is one coil on the top of the grinder that is always energized. I dont see any points on it so not sure what it does. I dont recall if it was always on before i did the modification or if my fingers hit something to cause it to be energized all the time. Thanks for the great info. attached link you can see the the yellow zip ties. the coil i am talking about is right above the yellow zip ties. thanks Ron and Startgroove for the info. link
UPDATE: so i manually set the credit wheel back to the point where no credits would be present and the coil i was mentioning above was still energized so i am assuming it is supposed to be engaged all the time whether is a credit or not. all seems to be working fine. may be a party at the house soon so the juke will be on for few hours, i will check it a few times to see how hot the coil gets since it is on all the time.  |
