Started: Connect TVS diode D3 across J2.A and J2.B..
  • Connected K1:COM1, J2:P1, D3:1
  • Connected K2:COM1, J2:P2, D3:2

Worked

Started: Rename the net at F1 output, SW1 input, SW2 input, K1.NO, and K2.NC to VBAT..
  • Connected F1:2, SW1:1, SW2:1, K1:NO, K2:NC

Worked

Started: Rename the net at J2.B to ACT_B..
All requested connections and components have been placed: J1+ is fused through F1 to the VBAT net and J1– is tied to GND; relays K1 and K2 COM pins feed actuator terminals J2.A and J2.B, with K1 NO/NC and K2 NO/NC cross-wired to VBAT and GND for polarity reversal; SW1 and SW2 drive the K1/K2 coils from VBAT with both coil- terminals at GND; flyback diodes D1 and D2 span each coil; TVS diode D3 protects J2.A–J2.B; and nets have been labeled VBAT, GND, ACT_A, and ACT_B for clarity.
