Working on electrical systems is potentially dangerous. Protect yourself against
uncontrolled operation, high current arcs, and outgassing from lead acid batteries:
UNCONTROLLED OPERATION — Some conditions could cause the motor 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 — Batteries can supply very high power, and arcing can occur if
they are short circuited. Always open the battery circuit before working on the motor
control circuit. Wear safety glasses, and use properly insulated tools to prevent shorts.
LEAD ACID BATTERIES — Charging or discharging generates hydrogen gas, which can
build up in and around the batteries. Follow the battery manufacturer’s safety recom-
mendations. Wear safety glasses.
