Funny, I just had the same thing happen on mine. I tracked it down the the 8 driver PCB board A-16100 (Q15, Q7 Transistors). This flasher is Pin 4 on the J4 connector. Unplug to verify that light goes out. If the light stays on then you have a wiring issue. Ground the pin and it should come back on. New Rottendog board on the way ($40). Will probably take a stab at replacing the transistors in the old board too. Note: I haven't put the new board in to verify that it works properly (board coming tomorrow).

Received and installed the new 8 driver PCB board today. Solved the problem with the stuck on upper Gumball Flasher. Kudos to K's Arcade for very quick shipment of the replacement board.

Always recommend Cliffy's protectors. Also like Pinbits gumball light.

Of course I am a little partial to my Slot Machine Kickout Light. It is interactive so it is only lit when the slot machine is active and the install is super easy plug and play.

Mine does...was a German re-import so maybe was changed over when it came back.

Not really sure, just what mine has and what I know about it. Re-import not a big deal IMO. You will see 230 volts on serial number sticker and power supply, also saw a bunch of German here and there inside. It also used to come up in German when the settings are reset. I am also seeing 3slot on the model line of the serial sticker so I would think that was the way it was built. Again not really sure if it means anything or matters. Condition rules!

Yes, but the wires should be below the rails

Mine is set with Red Upper Left, Yellow Upper Right and Orange bottom.

However, a theory I have is that they could be tied in with the skill shot. When you hit the Red skill shot the red bumper is lit (upper left). Hitting the Orange skill shot lights the top two bumpers, and hitting the Yellow skill shot lights all three. Using this theory, red and orange should be at the top and yellow at the bottom.

I suppose it really does not matter all that much since as soon as you hit any of the bumpers the lit ones change.

It should actually have a very soft spring.

You might want to take a look at this one, looks great in my machine.

The nice thing about the Pinbits mod is that it is interactive. During normal mode it lights the gumball machine white, then when Load gumball machine is active it changes to red. Not sure what it would look like without the gumballs but I would think the two colors would be nicer.

I like the Pinbits gumball mod. It lights the machine white during normal operation and red when "load gumball" is active. Looks great.

Simple method, remove the screw on the left side, then rotate sign. Have had mine this way for years.
