I was playing AFM lately, and I noticed the left flipper was "slower" to return to its resting position than the right flipper.
If I cradle the flipper, the longer I cradle it, the more the flipper "sticks" in that position and takes longer to go back to its resting position. Testing this with the PF up, you can see the left flipper takes longer to return to starting position and doesn't even make it all the way back in the video below:
Thinking it was mechanical and having rebuilt flippers before, I was happy to order the assembly from Pinball Life. After swapping my old one for the new one, I thought the problem was gone, but alas, it has returned.
I have noticed that there is a "humming" noise that comes from the coil once I release the cradled left flipper button. See the below video from today to showcase what I am trying to explain:
I noticed this game has no fliptronics board, so it looks like it draws power directly from the PDB, which is a bummer considering this game has a RottenDog board in it from 2016.
Ready to learn how to diagnose and troubleshoot this one....! Any ideas?
