PTO Speed Selector Sensor/Switch 2 Circuit/Open
The second PTO speed-selector switch input is open. Switch 2 typically encodes a binary or multi-bit code together with switch 1 — together they select one of several preset PTO speeds. With switch 2 broken, only the half of the bit pattern is available, so several presets cannot be reached.
