Engine: Electricity

1. A The coil burnout may be caused by insufficient voltage applied to the coil (below 85% of rated voltage); however, excessive voltage applied to the coil (above 110% of rated voltage) will not cause a burnout.
2. B The coil burnout may be caused by excessive voltage applied to the coil (above 110% of rated voltage); however, insufficient voltage applied to the coil (below 85% of rated voltage) will not cause a burnout.
3. C The coil burnout may occur with a normal voltage applied to the coil (between 85% and 110% of rated voltage) if accumulated dirt prevents proper seating of the armature to the magnet.
4. D The coil burnout may occur with a normal voltage applied to the coil (between 85% and 110% of rated voltage) if the armature is allowed to seat against the magnet with no air gap.
