               Aircraft high-tension magneto is a self-contained unit delivers high voltage to Spark plug, incorporating a coil, points and distributor. Coil having primary and secondary winding, step up the voltage to a spark-generating level, turn it into timed high tension electrical pulses, and sends it to the appropriate spark plug               Magnetos are fixed with manufacturer’s data plate  with either ‘L’ or ‘R’. The L or R does not refer to the position on the engine, but to the magnetos direction of rotation. In one instance, a left-hand rotation magneto was installed in the position where a right-hand rotation was specified. The result was a rough running engine with reduced power and the associated possibility of destructive detonation.              It is important to ins...
