: The primary coil builds up low-voltage current as the magnet rotates. When the breaker points open, the magnetic field collapses instantly, inducing a high-voltage surge (up to 20,000 volts) in the secondary coil.

Many vintage Scintillas feature oil cups. Use only a few drops of high-grade instrument oil every 100 hours of operation. scintilla magneto manual

Clean the contact points using a hard-finish paper or a lint-free cloth saturated with pure isopropyl alcohol. Never use an emery cloth or sandpaper, as abrasive grit will embed in the platinum contacts and cause rapid pitting. : The primary coil builds up low-voltage current

If you cannot find the exact model, look for the "Scintilla Magneto Service Manual" (often a green cover). This generic manual covers 90% of the adjustments. Use only a few drops of high-grade instrument

Tolerance levels for bearing wear and magnet strength. 4. Timing and Installation

Inspect the contact surfaces. Light graying is normal. If the points show deep pitting, heavy oxidation, or a distinct "hill and valley" transfer of metal, replace both contacts as a matched set. Do not attempt to file modern tungsten points unless performing an emergency field repair.
