Weber State University (WSU) – Department of Automotive Technology – Ardell Brown Technology Wing – Transmission Lab.

This episode covers how to use the incredible Hioki RM3548 Resistance Meter for Fuse comparisons and diagnostics This information applies to almost any other hybrid or electric vehicle on the road today.

This video helps cover content related to the 2017 National Automotive Technicians Education Foundation (NATEF) Master Automobile Service Technology (MAST) Standard task 6.A.2 “Demonstrate knowledge of electrical/electronic series, parallel, and series-parallel circuits using principles of electricity (Ohm’s Law).”and 6.A.3 “Demonstrate proper use of a digital multimeter (DMM) when measuring source voltage, voltage drop (including grounds), current flow and resistance.”

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 joining the Weber Automotive program, visit:
