My cyclone has an insert light that is always on (6X bonus multiplier). This lamp is your typical removable socket on an under-playfield PCB. Suggestions on where to start? Would this be a transistor or diode on the main CPU board? Is it possible its something on the under pf PCB?

I just went thru the lamp test and I have other issues. The comet 20k, 40k, 60k, 80k come on when they shouldn't when certain other lamps are activated.

I guess I have a bigger issue than I was hoping for. I recently did a pf swap, possible for shorted wire to cause issues or is this definitely a board problem?

Is there a way for me to isolate the potential bad diode or which wire might be shorted?

Thanks for the link. I'll take a look in the next day or two and hopefully figure this thing out. Appreciate the help!

Wait, what? Even in single lamp test this is normal?

Oh wait, just read again. I know what you are referring to. I have it set to 4x as default. So when game starts, 4x is lit, but so is 6x (which is my problem).
