Hi guys,
I am not a great technician, but I rencently started to try repairing a Twilight Zone pinball.
It seems that everything is okay, but in fact, hald of the coils are not functionning..

In test mode, when I try the coils, the coils from 1 to 8 are not functionning, then from 9 to 16 perfect. it follows with the magnets, which are in perfect working order too..
Also, the left down flipper is not functionning too, like strange behaviour..maybe some Q's to change ?

Any idea ? I'm also very looking forward to play, it's so frustrating to see the machine like... working except this !
Many thanks for the help.

Hi,
How can I know the ones I need to check ? From view, they all look correct...
I'll check and come back to you..maybe I looked bad..

Many years ago, I had the same troubles with a MB, and I had to change like an U, something.. but I can't remember how I can understand which U is linked with which coils...
