Hello everyone,
I got the Husqvarna AM415X from my father because it supposedly no longer works, and I wanted to try repairing it myself. It has several sensors for collision detection, and one of them seems to constantly detect a collision.
I identified the faulty sensor, and indeed, there wasn’t much left of it on the board. The board seems to be completely encased in some kind of epoxy resin, so after removing the defective sensor, the contacts didn’t look great anymore either.
Since I couldn’t figure out exactly which type of magnetic sensor was originally used, I ordered a random one that looked similar and soldered it onto the board. Unfortunately, the sensor didn’t work. On top of that, I made things even worse when I accidentally touched two of the sensor’s wires with the multimeter, and now I think I damaged something else as well.
Is there still any way to salvage this, or did I completely break it?
In principle, I’d even be fine with just bridging the three now non-functional sensors so that it simply keeps driving — because otherwise, it works perfectly.
A completely new board would cost €300 plus the software installation from the Husqvarna shop.
If anyone has an idea, I’d really appreciate it!
