Hi all. The extra ball button on my #NF stopped working after installing LED bulbs on the Playfield. I didn't mess with anything near that button, but I did try to take off the launch / no fear button and failed at it, so I stopped. I put the wires back on that button properly and it works fine, and the wires don't seem to be shared with the extra ball button, however, the extra ball button does not work now.

Any ideas?

Thanks.

Maybe a photo of the wiring would help.

How does the existing wiring compare to what the manual says should be there?

The existing wiring wasn't touched, so it is what the manual says it should be. Here is the extra ball button.

All wires on button, bottom left orange/white looks like it needs to be pushed on more? Gotta be something easy.

Unfortunately that didn't work. I also tried to jump the wires and it didn't work.

The launch button light uses the same yellow gray wire that the start button and extra ball button lights use. Check to see if the wire connection on the lauch button is good. It may have come loose while you were working on it.

OK thanks.

It also seems as though the slingshots aren't working now either.

Fuse or wiring.

Any insight on where to start looking? The fuses in the back box seem to be ok.

If fuses look ok doesn’t mean they are good, so game will start, no slingshots or buy in? Check continuity on fuses with a digital multimeter set to ohms or continuity audible. I still think something got knocked loose while you were doing the led conversion, like a wire connector somewhere.

Yes I did. Ok I will check fuses, thanks.

Correct, the game will start but the extra ball button and slingshots are not working. I will check the fuses again.

Thanks.

Led installed in the extra ball switch? Would check the bulb it's self sometimes they are a little large.
Had this issue when LED install you could not get enough depth on push to trigger switch

There is no led in the switch.

It seems as though the extra ball light, slingshots and kick back are not working.

Tests - Switch Edge - push button in. If it doesn't work, but you hear the switch click. Then your changing playfield bulbs may have hurt your CPU.

So its looking like I fried the ULN2803 array on the CPU board. I am impatiently waiting for the replacements from Marco (and also Amazon - https://amzn.to/3b8pesg) to show up tomorrow!

I will certainly post the results, and I thank you all again for the help.
