(5) Direction control switch

With the key start switch in the ON position, 24 volt power is supplied from the batteries via circuit breaker #9 to the electronic transmission control and via circuit breaker #1 to the AVSpare Monitoring System.

Electronic transmission control (2) receives a signal from the direction control switch (5) for the direction that is currently selected. The electronic transmission control applies a signal to the transmission solenoids (1) depending which gear is selected. The signal is then sent to AVSpare Monitoring System (3) via the AVS Data Link to the speedometer/tachometer module. The speedometer/tachometer module will display the actual gear in the display window. Actual gear indicator (4) displays the gear which is currently selected by the transmission.
