5.8 Electrical systems :
5.8.1 Ignition is only permitted by means of a single ignition coil and single spark plug per cylinder. The use of
plasma, laser or other high frequency ignition techniques is forbidden.
5.8.2 Only conventional spark plugs that function by high tension electrical discharge across an exposed gap are
Spark plugs are not subject to the materials restrictions described in Articles 5.13 and 5.14.
5.8.3 Other than for the specific purpose of powering KERS components, the primary regulated voltage on the
car must not exceed 17.0V DC. This voltage is defined as the stabilised output from the on-car charging
With the exception of any KERS or capacitor circuitry or coils being used solely to provide ignition, any
device with a current requirement greater than 50mA or a power requirement greater than 1W may only be
supplied at or below the primary regulated voltage.
Only capacitor discharge ignition systems (those which generate a spark by means of closing a switch
which then discharges a capacitor through the primary side of the ignition coil), are permitted to provide a
voltage higher than the primary regulated voltage to an ignition coil.
Other than any parts being used to supply a higher voltage to devices such as those described in the
previous paragraphs, no device may step up or increase the primary regulated voltage.

Does it run off the engine as in regular cars?
or is it more innovative as in the 1998 McLaren were brake energy was used to generate electrical power that is stored in batteries. This electricity is then used to run auxiliary pumps on the engine to push out an additional power.
Is it possible to run the entire cars electrical and hydraulic requirement (including ignition) with KERS (the capacity will not be limited as it is not used for propulsion)?
"I too also wondered why someone didn't use KERS to power all auxilliaries, such as oil pump, water pump, and hydraulic pumps."
Normally, what you suggest would make sense. And in fact, many types of vehicles use electric power for engine auxiliaries like coolant pumps, A/C, or power steering/brakes. But an F1 car is a peculiar situation. An F1 engine is primarily designed to operate at wide-open-throttle conditions 95% of the time, so all of the engine-driven auxiliaries can be optimized for this operating condition.
A mechanical drive system, like gears or chains, is much more efficient and lighter than an electrically driven system. Assuming that no speed variation between the engine and accessory is required.
Currently, most automotive electrical systems for things like lights, stereos, etc. are limited to about 42VDC. The reason being that higher voltages would present a safety hazard. Higher voltages would require smaller and lighter gauge wiring, but would not be safe.
F1 electrical systems are usually pretty minimal, since the cars don't have headlights, cooling fans or starters.
