Fuel

Oxygen

?

• Heat

• Electricity

• Petrol

• Diesel

What is a Volt?

• Pressure

• Quantity

• Flow

How does the coil transform power from 12v to 40kv?

• The electric magnifies by being wound another wire.

• Using electro-magnetic induction

• Power enters secondary winding and is forced into primary

• Thick oil inside coil helps to magnify it

• wrong fuel type

When the contacts are closed and the coil is saturating this is known as?

• Dwell period

• Timing advance

• Timing retard

• Back EMF

What function does the condenser provide?

• Stores back EMF

• Adjusts spark

• Switches off points

• Steps up voltage

Which tool would be used to test coil?

• High amperage spark meter
