I pulled the glass off and “propped open the hood”, as it might be, exposing all of the machine’s electronics.
I took the power switch mounting plate out of the cabinet and tightened the switch nut, making the switch nice and tight, giving a little better sense of safety when flipping the machine on. The switch had be rattling loosely under the machine when you flipped it on and off.
There are a lot of relays, leaf switches and motorized controllers in the cabinet under the playing field as well as mounted to the playing field and in the head of the machine where the scoring reels are located.
I manually tripped the bonus counter and tested that all of the lights for the bonus on the playing field are working. I took two bulbs from the playing field and put them in the indicator lights for the Quarter slots.
I learned how to set the credit settings for the coin slots, finding that you have 8 choices…
2, 3, 4 or 5 for 1 coin
2, 3, 4 or 5 for 2 coins
so 2 for 25c, 3 for 25c 4 for 25c or 5 for 25c
2 for 50c, 3 for 50c, 4 for 50c or 5 for 50c
The two coin combinations require the second coin before giving the credits on the credit reel.
Another curiosity is that the credit reel goes to 28, but you can only get 16 credits max no matter how you set the credit settings.
I closed the machine back up for the day and slid the glass back in to keep the cat from being too curious and getting into the playing field.
Time to read up on the different sequencers and see if I can find the one that turns off the GAME OVER light and lets the scoring reels reset.
