FORWARD DIRECTION OF TRAVEL

When the accelerator pedal for forward travel is depressed, the accelerator sensor output voltage at terminal
1X13:24 is less than 7.5 Volt.
When the accelerator sensor output voltage is less than 7.5 V, a logic circuit integrated in the electronic
traction control applies battery negative to contactors 1K12 (right-hand motor) and 1K22 (left-hand motor)
with the help of the two transistors for forward direction of travel.
In this way, switch 1S12 in the accelerator sensor does not control the directional contactors and it is therefore
electrically wear-free.
