SIGMA Reel Games / Re: Sigma 50-B jumper switches help for changing payout percentages

This gives you 10 possible jumpers, of which it's likely that only the first 8 are being used. I can't see in the blurry photo but my guess is that jumper#1 is on the left. You can Google how to find pin 1 on a 20 Pin DIP to be sure. It usually has a small mark to identify #1. If I'm correct, it is currently configured with 1, 3,4,5, 7, and 8 closed/jumped. Unfortunately, that does not agree with any of the % settings on the chart. According to the chart, the % is set using jumpers # 1, 2, and 4, and I do not see a combination that matches what you currently have. To get 98%, you want jumpers on 1, 2, and 4. Right now, of the 3, you only have #1 and #4 jumpered and I don't see that combination in the chart, so I've got no idea what it's currently doing. My guess is that you can add a jumper to #2 and you "should" be at 98%.
The chart does not say what all the other jumpers do, so I would not mess with them yet. Try just adding a jumper to #2 and see if it loosens up.
By the way, before you solder anything, remove the DIP header from the socket so that you are not working directly on the board itself. Use a good quality pencil iron, not one of those pistol grip high heat nuclear things that melt everything.
Good luck. Post more pictures when you can.
