Well, in the middle of a game the other day, the swamp gremlins decided they wanted to keep my game ball for themselves. the swamp lockup kickout stopped working.
Now, I’m a complete novice when it comes to game repair and I have eyesight issues, so working under the playfield can sometimes be comical, bare with me please.
Once I retrieved the ball from the swamp, I lifted up the playfield and tried to narrow down the issue.
I inspected the swamp area under the playfield for any noticeable issues. I noticed there are two solenoids in the swamp; the Swamp Release (coil-AE-30-2000) moves the ball to the Lockup Kickout (coil-AE-26-1200). Visually (which is a term I use loosely) everything looks intact, no noticeable burn marks or disconnected wires, the mechanics of the solenoids move and spring back smoothly, the plunger looks to be ceramic.
Single Switch Test:
I then ran the system single switch tests. I did not realize the swamp had so many switches; swamp lock upper, center, lower and lockup kickout. All switches tested open and when pressed would test closed. So it looks like all is fine here.
The swamp release (T4.28) solenoid tested okay, but the lockup kickout (T4.08) did nothing. I rechecked the solenoid, making sure it was secured to the playfield and rechecked the wires, retested and still nothing. The other solenoids in the machine also seemed to test fine.
Multimeter Ohm tests:
Understand, me using a multimeter (Klein mm2000), is like a monkey performing acupuncture, but it was time to break it out. I found the following post as a how-to reference: https://pinside.com/pinball/forum/topic/how-does-one-test-a-coil
I have used an mm less than a few times in my life, so I tested a few different coils to make sure I was getting proper ohms readings. I turned the mm to the ohms position and touched one lug with the black lead and touched the opposite lug with the red lead.
Swamp Release – 39.9-40.6 (AE-30.2000)
Lookup Kickout – 10.5-10.6 (AE-26.1200)
Right Slingshot – 14.6-14.7 (AE-27.1200)
Chair Kickout – 10.6 (AE-26. 1200)
Some have pointed out that the lockup kickout solenoid coil should be a 23-800 instead of a 26-1200. Both of my manuals call for the 26-1200 and this solenoid has been in use for years and up until now has worked fine, so I do not believe this to be the current issue.
Where do I go from here?
If I need to use the mm to test anything else, please include a how-to-for-dummies (I can see some of you shaking your heads lol) I mean, machine on/off, mm switch set to, where my black and red leads go. I have never soldered anything either, and unfortunately, this may be in my future in order to correct this issue.
The TAF does have new Rottendog MPU and Driver boards, installed about a year ago.
Thank you for any help you can provide.
I have only gotten this far because of the helpfulness of the other posts that I found:
and a few others.
