The black & yellow were crossed, so hers is a new photo. Does the yellow wire just below the gx tag going into the motor operate the oil. Sensor switch,?
Does the black wire going across the top of the motor go to the ignition?
Rather difficult alternating black & yellow wires
Star tech,
Your diagram is correct. The sensor has the yellow wire at the lower mower part. The switch wire goes to the wire going back towards the spark plug.
Trouble is, the new switch doesn't work.
