a couple of weeks ago i posted that the left slingshot on my royal rumble pin was kicking nonstop. i got some tips here on how to
fix it and i did. the other day i was playing a game and noticed that the left kicker was not as sensitive as the right one. i went to adjust it and now it doesn't work at all.
on top of that the lower playfield drop targets dont reset and the vuk to the upper mini playfield is not working either. they will all work in test mode but not during game play.they will also fire if you have a game going and you remove the ball and wait about 60 seconds. can anyone help with this?thank you.
 
When you say that they work in test mode, do you mean all the coils fire? Have you tested the switches for each of the coils? I'm guessing that all the switches are on the same row or column. You most likely have an upstream wire loose and this is causing all the switches in that row/column to not register and therefore not fire the coils.

So, do a switch test, see if the switches for those coils work. If not, look for a loose wire to one of the switches under the playfield. If that doesn't solve the problem, we'll need to look further.
 
when i do a coil test in diagnostics all the coils fire. sorry to be ignorant,i know nothing about electrical but im trying to learn.

Go into the Diagnostics, go to Switch Test, and test the switches. You'll probably find that all the switches do not register for the coils that aren't working. If this is the case, look for a wire that has come loose on one of those switches. I'd start at the slingshot first.

I downloaded the manual from IPDB and all the switches are in the same column. Most likely you have a switch wire loose at the slingshot that is causing the switches downstream from registering. The downstream switches are the VUK, D, E, A, D drops. This fits in with what you are seeing.

The left outlane, and left return lane are upstream from the slingshot switch. See if they work in the switch test. If they don't, it may be another issue because then the whole column is dead.
 
i cant find any loose or broken wires. looking at some old de repair stuff i got from pin repair before it shut down it looks like i may have shorted a row chip.
not sure though.this is all very new to me.gota learn this sometime.
 
Do the switch test, goto into the switch edge test and manually activate the associated switches for the things that are not working. Did you adjust the slingshot switch with the game on ?? thats a big no no, but if you did then yes I could see if you somehow shorted out that column

You've gotten some good advice about the switch edge test (honestly the best advice that could be given). The machine gives you the tools to track this stuff down (to a certain extent) - make use of them the best you can. At this point, all available evidence points to a switch problem, not a chip problem. Don't make it more difficult than necessary, and you need to thoroughly eliminate one possible cause (i.e. wiring or switches) in this case before proceeding to another possible cause (chip on board).

On the other hand, if you were adjusting a live switch with a metal tool, well, who knows.

When you remove the ball from an active game - after a set period of time, say 20-30 sec - the game will automatically start firing all of the coils in sequence to try to find the "missing" ball - the game assumes it is stuck somewhere. So that is normal.
 
Did you do a switch test in the diagnostics? As others have said, since you haven't found any lose wires, you now need to perform a switch test and test all the switches in the column that is giving problems. While you are at it, test all the other switches for good measure.

Test:
Left Outlane
Left Return Lane
Left Slingshot
Super VUK (Right Side)
D drop
E drop
A drop
D drop

If none of these work, the problem is most likely with the column and we'll need to start diagnosing that issue. Finally, if you don't have a manual, download it from IPDB.

Thank you to everyone for all your help. with your recommendations I'm sure i will get it working soon.and yes, i had the power on and had a screw driver loosening the slingshot switch. Rookie mistake i wont make again. (kicking myself for that one).
 
i did the switch test.none of the switches in row 3 are activating. on the switch matrix chart it says Q53. i checked for continuity on the green/orange wire all the way up the chain to the cpu. checked the pin.it looks good. and i have continuity onthe wire for that row. did i burn out a transistor?

From what I can read on the schematics, I think you are right. Unless I'm mistaken, from what you have been describing I think it is column 3 (not row 3) that is giving you the trouble. You can easily check Q53 with a multimeter on the diode setting. The LS244 could also be causing problems, but the first thing to check is Q53.
