TEC Controller Logic Chart
Each line of the following chart identifies the necessary
component position (INPUTS) in order for the TEC con-
troller to energize the appropriate OUTPUTS for ma-
chine operation.
Example: To start the engine with no operator in the
seat, when the ignition key is in start, the traction pedal
is in neutral and the parking brake is applied, the glow
plugs and other necessary engine starting components
will be energized.
