What is a primary maintenance advantage of solid-state magnetos?

• A. Wear.
• B. Corrosion.
• C. Voltage drop.
• D. No wear; no recurring inspection.

Answer: (D)

Solid-state magnetos use electronic switching instead of mechanical breaker points, so there are no moving wear surfaces. Because there are no wear-prone contact points to service, the maintenance burden is greatly reduced and there’s no need for regular point-gap checks or timing adjustments. Once installed, the spark timing stays stable and doesn’t require the routine point maintenance that traditional magnetos need. The other issues listed—like voltage drop or corrosion—were typical concerns with worn points, not the ongoing advantage of solid-state designs.
