It even feels like it's not the correct place to cut. I'm afraid that cutting there would cut off the power supply of the device. I would need to see the whole device, where are relays, etc.
Futhermore, I am confused - what are those two MOSFETs doing there? Those KND3403A...
Hello @p.kaczmarek2, as I understand that MOSFET 1 is directly connected to L wire and the MOSFET 2 switching low voltage as as you can see it is connected to the SOURCE of the MOSFET 1.
What I am confused is that not all relays are connected to the L wire, only pins of relay L2 and L3. The pin L1 goes on DRAIN connected to the MOSFET 2.
So as I am thinking now it would may work if I cut it L track before the cap 0.01nF as I marked on the picture below for the reference. But I am not sure.
