And I come to you guys for help. * Reader alert * I'm a pinball repair noob, this is my first machine and learning as I go.
So I have a Last Action Hero that's been pretty reliable this past year. Suddenly while playing a few days ago the right flipper randomly stopped working completely (mind you, it has stopped briefly a few times before but came back to life after a short time). Left flipper is fine.
I've tried my best to do my research, search forums, watch videos but I still cannot diagnose the issue. Here's what I've done and what I know:
I've checked the simple things. The flipper button switch is good, I can use the right flipper button to eject a ball to trough in diagnostics.
The flipper mech itself looks good, springs not broken, I can manually flip it smoothly, does not bind or seem to be missing anything.
End of stroke switch looks good. Touches and opens when it should.
The wires soldered to the flipper coils seem fine. Theres 2 connections on each coil and they are in tact.
Moving on to the flipper board. Theres four fuses. I was able to take out F1 and F2 and use my multimeter to test resistance and continuity and they are good. However I cant remove F3 or F4 because they are soldered in?? Is it common for people to solder fuses to the fuse clips? Anyway, I ordered a solder sucker so I can attempt to desolder the fuses and test and/or replace them but according to what I've researched F3 and F4 actually control the working left flipper anyway.
I've also learned I dont know how to use my multimeter almost at all. To test the coils I believe I should be able to turn the machine on and without starting a game, with my DMM on DC put the black lead to ground and put the red lead to the joint on the coil and it should read 50volt.
Well...I get nothing on either flipper when I do that, clearly I'm not doing something right. I also wasn't sure what exactly I was suppose to ground to, so I've been touching the black lead to the ground strap in the cabinet.
Alright pinsiders....please can somebody help me in ways I can understand? This is my only pin and if I cant get it up and running, I dont know if I'll make it through social distancing.
If it's something that is going to be something beyond my capabilities I fear it may be some time before I can get help here to service it with all the commotion in the world.
I include a picture of the flipper board if that helps. I know this was long, just trying to document what I was and wasn't able to figure out.
