Hello, in accordance with the explanation of the solved problem, I attach to the message regarding the automatic charger of the forklift batteries type STC 24/50 a diagram of the device, and a photo of the plate with a visible place of the presented fault. Regards.

My charger gave no sign of life, no LEDs illuminated, no relay engaged when the battery was connected (and it should audibly 'snap' even if there is no mains power). - The quadruple D-type HEF40175BT (SMD) flip-flop was faulty.
