1 — OVERVIEW
Working on electric vehicles is potentially dangerous. You should protect
yourself against runaways and high current arcs:
RUNAWAYS — Some conditions could cause the vehicle to run out of control.
Disconnect the motor or jack up the vehicle and get the drive wheels off
the ground before attempting any work on the motor control circuitry.
HIGH CURRENT ARCS — Always open the battery circuit before working on
the motor control circuit. Wear safety glasses, and use properly insulated
tools to prevent shorts.
