129JPT10-4B+KEYSupplies B+KEY to the circuitry on the STM via the over-the-mast cable when the key switch is closed.
130JPT10-3B+ESTOP Supplies B+ESTOP to the K1 relay coil on the STM via the over-the-mast cable when the EPO switch (S21) is closed. This closes the relay and supplies B+ESTOP Relay to circuits on the STM.
131JPT10-1B–Supplies B– to the carriage via the over-the-mast cable when the battery is plugged in.
132JPT9-612VPSupplies 12V from the STM power supply to the Carriage Manager via the over-the-mast cable. The 12V is used to power the CM power supply and supplies voltage to all components using the 11.3VP. If not present, check voltage at STM JPT9-6 and see if IL1 is lit.
133JPT9-5DEADMAN2Output from deadman switch S23 informs the microprocessor on the STM that the switch is closed and lights IL2 on the STM.
134JPT9-2DGNDSupplies B– to the carriage via the over-the-mast cable when the battery is plugged in.
135JPT9-4TRANSMITThe wire that carries the communications from the STM to the CM. No usable information can be gained by measuring the voltage on this wire.
136JPT9-1RECEIVEThe wire that carries the communications from the CM to the STM. No usable information can be gained by measuring the voltage on this wire.
137JPT9-3DGNDSupplies B– to the carriage via the over-the-mast cable when the battery is plugged in.
138JPT6-1CHAThis is a square wave generated whenever there is movement of the Steer Feedback Encoder. Voltage varies between about 4VDC and about 0VDC as the encoder shaft rotates. The frequency varies directly with the speed of the Steer Motor. The STM uses the quadrature phase relationship between CH A & B to determine direction and speed of Steer Motor.
