Diesel Technology II expands on the classroom and lab experiences from Diesel Technology I and focuses on diagnostic and repair of diesel electrical systems used to power buses, tractor trailers, electrical generators, construction and farm machinery, and similar equipment. Utilization of analog and digital meters, wiring diagrams, and other diagnostic tools are stressed as students are introduced to automotive electrical theory, batteries, charging systems, starting systems, wiring repairs, brake systems, clutch systems, suspension systems, lighting systems, and accessories. This lab operates as a repair shop, and students gain experience working on customer projects.


When You Finish

Upon completion of this program, students are prepared for entry-level employment in the diesel technology industry.  Students may also continue their education in 2 and 4-year degree programs, begin apprenticeships, or enter the military.

Student Evaluation

After the completion of two years in the program, students are evaluated on technical and essential skills. The Technical Skills Evaluation documents the Diesel Technology skills learned. The Essential Skills Evaluation documents the workplace skills all WCC students learn. The documents were developed by WCC teachers, in cooperation with business partners and industry advisory committees, and are updated each year.
