I just finished restoring the back assembly on my 1962 Williams World Series. In powering it up to test it, I found that the credit unit starts at “-1”. It is a blank spot, two positions before the number 1. I was wondering if anyone could provide a sanity check on that as compared to their machine.
I took a few videos. If at position 1, I can reset the machine “for free”. Same If at position “0” at which point it decrements again. At that new position I am calling -1, I can’t reset the game and have to load a credit before I can reset.
It feels “off by 1” but I don’t understand how that can be given the “keying” of the gear unit and the reel. Any advice appreciated.
First video shows me repeatedly resetting:

Second video shows me loading the first credit but still being at 0 position.
