Ok, first off, let’s start by saying 5 ball. Roll over lights are dropping card flags, scoring 50, spins roto but not turning off the insert. Subsequent hits score 50, spins roto but should NOT score since rollover should have been unlit with first hit. This seems to happen on several numbered cards, 2 numbered cards being the only ones that unlite when rolled over. AKQJ10 targets score 50 all the time, even on the roto, but do unlight when hit and drop their card flag. Once all cards are hit, however, the specials never light up, even though all card flags are dropped, and I believe this may be because not all lights are unlit.

I have the schematic, I’m rusty at ladder logic, but I guess I’ll stare at it some more. I think the Grimlins are in the card flag sequencer relay bank, but I need to know what all the 5-3 ball adjustments do to the ruleset to better understand what is going on.

From what I can tell, correct operation is the lit cards should all go off as they are scored. Getting 2-9 lights specials at inlanes. Getting all cards lights one of the A thru 10 inserts and scores a special when the card target is hit on playfield or on roto.

Right now, my cards are not unlighting when rolled over or hit on roto for numbered cards 2-9, but not all of them, 5 and 3 are going out, it scores 50 and drops the card flag, and subsequent rollovers of 3 or 5 just spin the roto target, and 3 and 5 are dead on roto when hit. The other numbers continue to score 50 and do not go out, but do drop their flag on the first hit.

Any suggestions kindly accepted on where to start looking.

Ok, for starters, I want to personally thank everyone who posted… your info is now captured here for the rest of the poor KOD owners like me in the future who arrive here with the same symptoms, all of which you have addressed very quickly and correctly, I might add. Whilst you were adding to the answer pot, I was reading other KOD troubleshooting posts when I came across a TimMe post that follows:

The same advice was shared here as well by runbikeskilee, and I am glad this info is out here for us to find. I know now to check this first before getting a chair, a rope, and a high place to hang myself when KOD goes brain dead.

Ok, this saved me not just tons of time, but f-tons of time. Not knowing to check the wingnuts and bracket would have cost me hours of pouring through the scat and aligatoring my way to oblivion. Imagine my surprise as all my symptoms disappeared after jiggling the end of the sequence bank and it jumps up in the slot and tightens right up. If you have a KOD and it’s acting weird, check the sequence bank out. TimMe you and the others paulace pinhead52 Runbikeskilee and jrpinball are my KOD saviors and I owe you all a couple of shots/rounds/hits if you ever bump into me. Special shout out to jrpinball for the roto unit. All working great now.
