ABOUT US:
Weber State University (WSU) - Department of Automotive Technology - Ardell Brown Technology Wing - Transmission Lab. Is your hybrid or electric vehicle's 12V battery going dead? Learn how to check the on-car 12V charging system (DC-DC Converter) with this video. This is the third in a series of videos on the Toyota Prius Prime as well as other Prius models. This episode covers how to perform the 12V Charging system (DC-DC Converter) functional test. This information applies to almost any other hybrid or electric vehicle on the road today.

W.S.U is a leader in Hybrid and Electric Vehicle education. This topic is taught as part of our 4-year bachelor's degree program. For information on joining the Weber Automotive program, visit: http://www.weber.edu/automotive

This video helps cover content related to the 2017 National Automotive Technicians Education Foundation (NATEF) Master Automobile Service Technology (MAST) Standard task 6.D.1 "Perform charging system output test; determine needed action."

This video was created and edited by Professor John D. Kelly at WSU. For a full biography, see http://www.weber.edu/automotive/J_Kel...
