       @penguin42 @Markus The caps leak, and due to its poor base material, the PCB becomes partially conductive.  The leakage is often so bad that the whole board is covered with black goo.  I had mine work again after a thorough clean and recap, but fail after a couple of months again with the SENS signal no longer going high.
