There are a couple of switches on the Bonus Unit that should trip when the Bonus count reaches zero.

One should let the K/Bonus Count relay relax and the other should fire the O/Outhole relay. Is your Bonus Unit reaching zero, and are those switches getting activated?

markg the bonus unit does go down to 0 and I checked the contacts and they all appear to be making and breaking correctly. But the k relay stays pulled. The only way to get it to stop is by manually pressing the hole switch. I’m very confused myself since I’m only 17 and this is my first em. Any suggestions will be greatly appreciated.

While a switch must appear to be closed to make an electrical connection, simply closing does not guarantee an electrical connection. If the contacts are dirty for example a closed switch will not conduct electricity. You could try cleaning the contacts of the lower Zero Position switch above (yellow-black wire to red-white wire) by putting a piece of paper or dollar bill between the contacts, gently pressing the contacts together and pulling the paper out. The first time you may get a grey line of soot on your paper. Repeat that 2-3 times until the paper comes clean.

If cleaning that switch doesn't get your K/Bonus Count relay to relax, check the On Subtract Bonus Unit switch above. It should open unless the Bonus Unit subtract arm is pulled in.

Does your O/Outhole relay fire? If not that could also be explained by dirty contacts on the upper Zero Position switch above (blue-white wire to green-black wire).

For a switch to work 3 things are necessary:
1) When open, there should be a small space between the contact points (duh)
2) When closing, the long blade's contact point should push the short blade's contact point enough to move the short blade
3) The contact points should be clean, which they usually will be if #2 is happening

markg thank you for the feedback I’m going to clean the contacts tomorrow and we’ll see how it goes.
