I then remembered that I was using a replacement rail magnet. I saved the original trigger magnet (worn off coating) and noticed it’s roughly 1/2 the thickness.
After re-installing the original trigger magnet, the trigger pulls were consistently registered. I’m a little suprised at how far inside the trigger the magnet resides. That would explain why the rail magnet didn’t work for the trigger.
I do still plan to tinker a bit though. It took two installs of the original magnet to register trigger pulls (maybe upside down or perhaps the stronger magnet magnetized the trigger magnet holder).
My meter shows a good connection between the frame batt- stud and the batt- pin of the HES. I shook the frame a few times and found it measured consistently.
I plan to pull the board one last time and ensure the underside of the board is clean where it picks up the frame ground. I did notice one of the solenoid connections is very close to the anodized frame. I added a little electrical tape to the frame to help.
I’m a little bothered by having to install the original magnet a few times. There’s nothing worse then something “just working” without knowing why…..says the recovering Embedded Systems Software Engineer.
Hope the long post helps the next guy. I do enjoy tinkering with AGD markers. The engineer in me marvels at how well thought out their designs are.
Regarding SW updates…is that something you (Tuna) still do?
