Nishijin Shiroi Kamome C wiring issues

[MichelleLee2019]

I am restoring my first pachinko machine and am learning along the way. Initially my issue was the jackpot lights were not working when the ball tray was full. I switched the top limit switch posts but now the jackpot lights only work when the tray is full. So obviously I have some wires crossed. Also the top light is on all the time. Which wires behind the power supply should go directly to the light posts in front of it and what should the limit switches be set on MO or MC? Also, I am not using that white plug behind the wires. What is that used for and were is it suppose to be attached? 44C554D1-FEEE-4C86-904F-1119C7ED7A07.jpeg Any help is appreciated.

Recheck your wiring. 2 individual cicuits.

1. Power in through fuse to common on low ball switch. Out of switch on NC (nomally closed) to low bulb socket.

2. Power in through fuse to common on prize switch. Out of switch on NO (nomally open) to prize bulb(s) socket.

3. Common or negative of power source to all bulb sockets. Be sure to keep uniformity on the bulb socket connections. ie: all commons to socket bases and powers (+) to the sides of sockets.

If the fuse isnt getting good contact in the back would that cause the lights to not work properly? I discovered yesterday but have an idea how to fix that part. There are two yellow wires attached to the low bulb socket, is that correct? White wires go directly to fuse or post screws. Is that correct?

Not sure about the wires, but yes, poor connection at the fuse would cause the lights to not light.

Have you checked the fuse for continuity to be sure it's good?

Have you cleaned the fuse contacts with sandpaper?

Two yellow wires connected to socket is correct.
Hook up your positive battery wire to white terminal, negative battery wire to orange terminal. The yellow terminal is not hooked up in your case.

The fuse is new but is there a way to check with an instrument if it has continuity?

If it's new you're probably OK, but yes, you can check it for continuity with a digital multimeter. Your meter should have a continuity setting. With it selected, when you touch the two probes together it'll usually beep. Find that setting, then touch the meter's red terminal to one end of the fuse and the black one to the other.

Also, make sure you've cleaned your fuse clips. Mine looked fine, but weren't. You could do the same continuity test with the clips. Put the fuse in place and touch one terminal to the metal clip on one side of the fuse and the other terminal to the clip on the other side of the fuse. In both cases, be sure you're not also accidentally touching the fuse with either meter terminal.

Or, just go ahead and take a little sandpaper to the inside of the clips until you see shiny metal.

It should read zero resistance instead of "open" with your multi meter.

Try incandescent bulbs, then polarity won't matter.
