HANDBRAKE CURRENT
Applying the handbrake actuates microswitch 1S4 and cuts off the battery negative signal at 1X13:9.
When the handbrake is applied and the accelerator pedal is fully depressed, a limited current of 250 A flows
through the traction motors. This allows starting uphill because the truck does not roll back when the brake
is released.
