I bought a 25V transformer and connected it up I put a quarter into the machine and it took it I tried pushing the buttons but they will not push only the bottom row(numbers only) will push in. Some of my lights work and some do not. The arm on the selector plate moves to the next dot but that is it. So it seems it is not getting power somewhere Any suggestions out there?
"High" Yeah, I have some suggestions;
First, a question; why are there three wires going to the transformer? There should only connection to the orange -chassis and green -AC input. the third is blue-signal and not needed at this time.
Next, it is item to oil the motor and gears before doing anything further. Use a good 20wt and be sure to put a drop on all cam faces as well.
-When credited the wiper blade should form a "V" as shown here:
http://s1192.photobucket.com/user/Rob-N ... rt=2&o=230 In this position the buttons should lock in when pressed. the wiper blade should not be able to be turned counter-clockwise in this position.
Failure to launch when both buttons are pressed can be caused by the following:
-Some letter groups being in the "EP's" bus on the and not enough credits to permit a start. Check the taper pins on the terminals right above the credit unit.
-Dirty or pitted contact fields on the credit wheel. If the box is stepping up to credit position this probably isn't a problem. A shot of contact cleaner is a good idea here.
-Pitted or misadjusted Blades on the stack right behind the signal wafer:
http://s1192.photobucket.com/user/Rob-N ... rt=2&o=233 Note that there are (at least) three different configurations of these boxes internally and the switch stack also looks different in each case. In general, when credited the set of blades with one long inside two shorter ones must not be touching either one.
-Pitted or misadjusted treadle bar start switches:
http://s1192.photobucket.com/user/Rob-N ... rt=2&o=232 These are under a removable cover at the top and bottom of the keyboard assembly. They must close with a bit of wiping (overtravel). Try pressing both letter and number simultaneously.
-The inability to get the letter or number keys to press in may be a lack of lubrication on the sliding spline that locks buttons in, try a little spray silicone injected into the keyboard assembly. Also check the positions of these screws;
http://s1192.photobucket.com/user/Rob-N ... rt=2&o=232 Wear on the cam that operates this linkage can cause the release screws not to be far enough inward to allow buttons to be pressed and stay locked-in. When the motor is running and box is "sending" this linkage moves outward thus locking in the buttons and not permitting any change to be made.
i have 93 of these old relics on location. In all cases they were washed with diluted floor stripper, rinsed in warm water and a vacuum was used as a blower to get most of the water out. This was followed by being placed a few inches above a radiator or out in the sun for a few hours and allowing an additional day to make sure the coils are dry.
Re-soldering the sockets and modifying the credit setup is also done.
