Electric shockIgnition HT is the most likely place to suffer a shock, up to 40 000 volts is quite normal. Use
insulated tools if it is necessary to work on HT circuits with the engine running. Note that high
voltages are also present on circuits containing windings due to back emf as they are switched
off, a few hundred volts is common. Mains supplied power tools and their leads should be in
good condition and using an earth leakage trip is highly recommended. Only work on HEV and
EVs if training in the high voltage systems.
