All ok except covering proximity switch, still have 5 volts when covered
Ok. If the prox switch is correctly adjusted, and it's still giving 5v on Pin B all the time (including when something is directly covering/touching the face of the sensor), then the prox switch is bad and should be replaced. There is a controller on the combine that monitors that voltage, and when it sees the voltage drop from 5 to 0, it sends 12v to latch the bypass relay so that the motor can run. Then when the level of the grain drops below the sensor, the sensor opens and the voltage on Pin B returns to 5v and the controller removes power from the relay, causing the motor to stop. |
