Magnetos generate dangerous voltages independently of the vehicle or equipment battery. Treat every magneto as live.
Connect your timing light or ohmmeter across the breaker points. Loosen the point plate adjustment screws. Slowly rotate the breaker plate until the light changes or the buzzer alters pitch, indicating that the points are just beginning to open at the exact millisecond the rotor hits its -gap position. scintilla magneto manual
When this post is connected to the engine or airframe ground via the cockpit switch, the primary circuit is short-circuited. This prevents the magneto from generating the high-voltage pulse needed for a spark. Safety Warning:
This guide will explore the history of the company, the key manuals available, the specific models they cover, and where to find the operation, maintenance, and repair information you need.
Over-lubrication is a primary cause of magneto failure. Oil or grease on the breaker points will insulate the contacts, causing the engine to misfire or fail to start. This link or copies made by others cannot be deleted
Use a hard-finish paper (like a business card) soaked in a little solvent to white away oil or oxidation between the points.
Store magnetos in a clean, bone-dry environment. If storing for extended periods, place a small desiccant pack inside the housing or wrap the unit in VCI (Vapor Corrosion Inhibitor) paper to protect the delicate internal copper windings from atmospheric moisture corrosion.
A mechanical switch operated by a cam on the rotor shaft. When the points are closed, the primary circuit is completed, allowing the induced current to build to its maximum intensity (known as the -gap position). Try again later
If you own a vintage aircraft, a classic tractor, or a piece of mid-century industrial machinery, you’ve likely encountered the . Known for their robust engineering and Swiss origins, Scintilla magnetos (often branded under Bendix) were the gold standard for high-tension ignition systems for decades.
The Scintilla Magneto Company was founded in 1915 in Switzerland. The company quickly gained an international reputation for producing incredibly reliable high-tension magnetos that could withstand extreme vibrations and environmental conditions. The Bendix Acquisition
is an essential piece of your toolkit. These historical documents provide more than just diagrams; they offer the precise technical steps needed to ensure your ignition system remains reliable.
Focuses on routine care, cleaning, and adjustments like checking the "P-lead" grounding or internal timing.
