Help! Twilight Zone with flasher and gumball issues!
recently started to work on my TZ. And i have solved a lot of the errors with adding new switches. One of the errors was the Geneva error of the gumball. I was kinda dumb... and i replaced that switch. But that switch was good and did not solve the problem. It's my first "modern" pinball and i was unaware that when i switch is not used for some time it starts giving an error even when it's good.
The problem is that the gumball is loaded.. and then the ball cannot be found. So my guess is that the opto right before the gumball is bad. However it does not give me a opto error! Can the opto be bad and not give me an error? Is there a way to test an opto?
Now for my flashers... none of them work. I replaced the fuse for F111, secondary flashers. However LED 5 is out. I think that's the 20v circuit LED. Can this be due to bad bridge rectifiers next to it?
Any help is very much appreciated!
