We have a solid state relay controlled by a Raspberry Pi, The relay is interposed o the negative wire between a 11-12V battery and a motor.
If I measure the voltage before entering the relay, it is correct. If I measure it on the output side I get 0.44V and the motor won't start. However, while the Relay is ON if I interrupt the negative wire and I connect it back, the motor works(While the relay is still on).
I'm not sure if it counts, but I use a LiPo battery.
What is it happening? How can I solve this?
Edit: This is the SSR that I use: https://www.aliexpress.com/item/2-Kanal-OMRON-SSR-Relais-G3MB-202P-5V-DC-2-Channel-Solid-State-Relay-Board-module/32830801262.html?spm=a2g0s.9042318.104.22.168424c4d4M3JQz
