7.14.2Check and discharge the capacitors
Attention!:
NEVER check the capacitors whilst the generator motor
is running! Charged capacitors can be lethal. Do not
contact the capacitors with bare fingers or non-insulated
metallic objects! In order to test the capacitors, the
terminal lead wires have to be disconnected using pliers
or a screwdriver with insulated handle(s). Once the wires
have been removed, the capacitors must be discharged
by bridging the capacitor terminals with a discharge
reactor.
