I have a cyclone that was running perfectly and now suddenly the right kicker / sling is not firing. It does score the points when hit so the leaf switches are registering. When in test mode the coil does not fire. I did notice some "machine gunning" with the kicker previously when it was working.

I replaced the coil (i know, not the most logical first step) and no luck. I do know it uses a "special" solenoid on System 11Bs that bypasses the CPU for quicker response, but i'm not sure if it has an associated fuse. Can anyone point me to that? I read somewhere the special solenoids have their own fuses but i can't figure out where those are, if they exist. I also doubt the right kicker has a single fuse only for itself but i hope i'm wrong as that would be an easy fix once i identify which one it is. Any clues or ideas would be much appreciated.
thanks for reading.

Ok i was wrong, The special solenoids are CPU controlled on cyclone.

Before i try the quick ground test, do you mean to touch ground to the top of transistor Q69 to see if the coil fires? I am double checking before i do this since i really don't feel like blowing the CPU board.

Today I checked:
DC power to the coil is present and it matches the value of the left kicker coil.
Q69 tests normal in diode mode on the multimeter.
Checked continuity to from the non-firing coil to the other coils in line and it buzzes ok.

Thanks for your help. i tried grounding the transistor and that worked - The coil did fire. At least i am seeing progress but now what? i double checked the transistor with the meter and it tests ok. Is it time to pull it and replace it or is there anything else to do first?

Nothing happens but i would kind of expect this because nothing is connected to the 1J18 pins so i imagine they are not in use. I didnt try 1J19 pin 6 which is what i believe is right kicker. Thanks.

Doing some more research and found this:

.... If the TIP122/102 and coil pass this test, and the coil still doesn't work in game play, the problem is more "up stream". All that is left is the 2N4401 pre-driver transistor, and the logic TTL chip that ultimately controls the whole process (a 7402 for the special coils or 7408 for the constant power solenoids), and the PIA 6821 chip.

Am I on the right track? It does fire when grounding the transistor at Q69 (TIP122).

Good news. I finally got around to working on this again and resolved the issue. I pulled the mbu and the 2n4401 and tip122 (Q68 & Q69) were testing ok but they were a little different on the meter vs. the similar components on the board. Decided to replace both and everything then tested similar to the other components, put it back in the machine, and the right kicker is now working perfectly. Thank you all for your help!
