Hi Pinside!

I recently spent some time refurbishing a lightbulb socket only to figure out weeks later, that it was the connection on a drop target switch that was the problem. The reason I mention that is because I own a Gottlieb Jet Spin that has flickering light issues on some of the bonus lights and extra ball lights. A friend suggested it was probably the bonus unit stepper rivets that needed cleaning. That seems logical to me, but I want to ask here first in case there is another relay or switch that activates the extra ball light instead of the stepper. Thanks if your familiar with the machine and can answer.

Thank you, @MarkG!

Lights all work beautifully. Thanks again, @MarkG!
Do you know off hand if Jet Spin's bonus is 1k to 16k or 0k to 15k?

It was 0 to 15. After cleaning it seems to be 1 to 16. I may have miss judged by a rivet, but I think I like this more. It seems to work.

I watched about 6 videos and they all go from 0 to 15. Further to your point. When it was set for 1 to 16. The specials turned on at 15 and then off at 16. Not much point in maxing the bonus. Fixed it. Thanks.
