Problems with vibration and Analog, why do they turn off?

Hello, how are you, I recently bought some dualshock 1 model (SCPH-1200), and I have a problem with the vibrator and the analog power button, In more detail, it turns out that when I vibrate my joystick the Analog turns off by itself, I can't play and I have to press the button all the time to enable it, I checked if I was making any shorts and/or if all the cables were soldered and they are all correctly, it is like the Analog lacks power and turns off when the Joystick vibrates
