Isolation Relay Wiring Diagram. Its submitted by doling out in the best field. If not check wiring.
Look at the diagram above. Check voltage on module with ignition off. Use copper wire 75ºc min only between disconnect switch and unit.
Large voltage spikes shorts etc.
Schematic diagram l2 notes. Red and blue wire should be 0 volts. You actually happen to have the relay oriented in your photo the same way the relay in the diagram is oriented. Ive added a diagram to this post to show what that would look like in a 2 wire run with the wyze getting power from a wall adapter and switching an isolation relay.
