As a newbie to the group, I would like to introduce myself. My name is Mike and I found this site during searches for more info on Universal slot machines. I can’t express how helpful this site has been with information that allowed me to fix a slot that I recently acquired. One of my hobbies is to buy up and fix broken arcade boards and pinball machines. During one of my pinball excursions, I came across a Twin Crowns slot machine. It was in perfect working order and the owner said he would sell it along with his pinball. Got a good price and it became mine. I recently won a Super Magnificent Seven slot from an auction. I figured I would try for it as the pics showed it to be complete but was advertised as broken. As both machines are Ultra’s, I figured I could swap parts around, if needed, to help troubleshoot any issues.
When I received the Seven’s slot, I plugged it in…lights came on … no displays lit up. That’s when I did a Google search and found your site. Awesome information. Re-seated the system board and got displays. Got all sorts of error codes too. Eliminated some by reseating the system board multiple times and doing a couple of ram clears. One issue was that the dollar bill acceptor was not connected properly. Finally got that straightened out. The, the unit would not accept coins. Had a quarter in the coin comparator as it was supposed to. Turned out the opto at the bottom of the coin mech was dirty. Now it would take coins and reels would spin. However, on certain wins there was no payout. I was going to swap system boards to see if the problem followed the board or the proms. As I lifted one prom out, I noticed one of the legs was bent. Straightened it out and, voila, payouts now worked. Dollar bill acceptor does not take any bills, I will look into that later. Just converted the unit to take tokens so that I don’t need to keep the hopper filled with quarters. Plus, in my state, it is illegal to own a slot if it takes and pays out money.
As great as your site is for help and documentation, I was not able to find any manuals on Ultra slots. Does anyone know where I could find such documentation? There are settings that I would like to validate and it would really be helpful if there were schematics too. I have two more issues that I am trying to fix. One, I am sure is heat related but will be a pain to troubleshoot without schematics. The attendant light stays on completely for about 15 minutes then will dim and finally go out. When pressing the attendant button after that, it will flash as it is supposed to. The other issue is that one of the reels is not quite lined up with the other two. I would like to know how to adjust that reel.
I am including a pic of my two machines.
Best regards,
Mike C.
