Hi everyone!
have a 12V DC pump rated max 26Amp
this pump is controlled by an autopilot(yacht) unit.
this autopilot unit has a max capacity of 20Amp so after burning several fuses and eventually the unit sent it to repair and technician told me to make external relay box.
the way it operates is reversing the polarity of the pump to turn port(left) or starboard(right).
technician suggested using SSR solid state relays 4 of them.
when i build the circuit the SSR got burnt almost inmediately it seems that when the polarity is reversed the SSR didn't fully discharge and shorted.
Q:how can i ensure the SSR is empty as soon as the actuator is disconected?
diode, resistor???? how?
thanks G
