Have a couple of flashers locked on. I cant find my damn manual anywhere. After accidentally swapping driver boards, i noticed the problem went away. Any flasher issues i have had on gottliebs always landed underneath the playfield. I have been through pinwiki and clays guide, and they mention a pre driver on the driver board, but not which ones. Can someone point me in the right direction?

Do they stay lit when you enter Test mode?

Have you visually inspected the relays on the underside of pf? Maybe the relay for flashers is stuck on, not energized, but physically stuck (?).

Pm'd you re: manual.

It is for Spring Break. I was able to track down a manual, it looks like the 2 flashers are tied to the transistor board under the playfield, but that wouldnt explain why switching the driver board fixed the issue. Looks like i have some schematics to study this evening.

Not coincidentally, i am also having issues with those particular coils blowing fuse as soon as they are activated. Two of these transistors were fried when i received the game. I installed new ones, but i didnt actually check the schematics, i just copied previous owners connection

One of the banks of three standups on my Raven gets stuck on. Sometimes one gets stuck, sometimes none come on etc. All three go to a chip on the driver board so you might want to look at that.

I've looked at the diagram approximately 100 times, and I just now noticed the q1-q4 assignments. Durp

All 4 of transistors from the board arebtesting out of spec, even though two of them are new. So i am starting from scratch to fix these issues.

So dumb question, the top gray wire from f12, should this go to the banded or non banded side of the coil? Or does it matter?

Is that the launch kicker ? Banded side.

Yes. Is it any different for standard 2 lug coils throughout? I asked the question initially because several coils from that fuse bunch are wired differently

The two launch kickers on mine (shooter lane launch and upper pf exit launch) both have the gray (888) on the banded side. Should be that way in the schematics too. Assuming the wiring is original, you should be able to determine which wire goes to which lug following the 3-digit color code in the manual (pg 41). In the schematics, the banded side of the diode is the tip of the triangle.
Also, I believe these two launch kickers are the only two things associated with fuse F12.
