Electrical Oddities

This course, “Understanding Electrical Oddities,” is a continuation of Dave Hobbs series on electrical issues and unique challenges related to troubleshooting vehicle voltage systems. Dave’s presentation will instruct on traditional electrical systems such as CAN, bus, and 3-phase motors and delve into the mysteries behind hybrid and electrical voltage HV leakage and the HV system main relays. This course will also cover overlooked essential subjects such as motor current draw, Ohm’s law, A/C circuits inductive and capacitive reactance, ohmmeter false positives in parasitic drains, measuring starter relay outputs, and EMI/RFI quick fixes.
