Electrical condenser assemblies and magnetos for spark ignition engines

A magneto having:

• a low tension coil;
• a contact breaker assembly having:
• first and second contact breaker points electrically connected in parallel with the low tension coil and;
• first and second electrically conductive members electrically connected to the first and second contact breaker points, respectively, the first and second electrically conductive members having first and second faces, respectively, facing each other but not directly electrically connected to each other;
• and
• a condenser assembly comprising:
• an attachment portion interposed between the first and second faces of the electrically conductive members of the contact breaker assembly, the attachment portion having first and second oppositely facing electrically conductive faces making electrical contact with the first and second faces, respectively, of the electrically conductive members of the contact breaker assembly, the first and second conductive faces of the attachment portion not being directly electrically connected to each other;
• and
• at least one capacitor electrically connected to the first and second conductive faces of the attachment portion.

A method of modification of a magneto having an armature with a low-tension winding and a condenser electrically connected in parallel with each other and disposed between a drive-end end-piece and a tail-end end-piece of the armature, and a contact breaker assembly mounted on the tail-end end-piece and having first and second contact breaker points electrically connected in parallel with the low tension winding and first and second electrically conductive members electrically connected to the first and second contact breaker points, respectively, the first and second electrically conductive members having first and second faces, respectively, facing each other but not directly electrically connected to each other, the method comprising the steps of:

• rendering the condenser substantially ineffective on the low-tension winding;
• providing a condenser assembly comprising:
• an attachment portion having first and second oppositely facing electrically conductive faces which are not directly electrically connected to each other;
• and
• at least one capacitor electrically connected to the first and second conductive faces of the attachment portion;
• and
• fitting the condenser assembly to the contact breaker assembly so that:
• the attachment portion is interposed between the first and second faces of the electrically conductive members of the contact breaker assembly;
• and
• the first and second faces of the attachment portion make electrical contact with the first and second faces, respectively, of the electrically conductive members of the contact breaker assembly;
• whereby the capacitor(s) of the condenser assembly is/are electrically connected in parallel with the low-tension winding.
