Tome nota de lo siguiente:

Cuando quiera hacer mediciones dentro de los componentes del distribuidor; use herramientas "no magneticas"

Los medidores, calibradores etc. de material que conducen magnetismo; daniaran las partes electronicas.

Estas fallas, se manifestaran en forma inconstante, dias despues.

El cobre, el bronce, el aluminio, no conducen magnetismo.
