Product Details

The Sierra 18-99555 Piercing Probe Set is a professional diagnostic tool designed for marine engine electrical troubleshooting and DVA (Direct Voltage Adapter) testing. This set features fully insulated probes with spring-loaded clamps that allow for hands-free operation during diagnostic procedures.

Key Features:

  • Stainless steel pin that self-centers and punctures wire insulation for quick testing
  • Spring-loaded clamps provide secure, hands-free connection
  • Fully insulated construction for safe operation
  • Color-coded design with one red and one black probe for easy polarity identification
  • Ideal for testing marine engine ignition systems and electrical circuits

This piercing probe set replaces CDI 511-9770 and is an essential tool for marine technicians and boat owners performing electrical diagnostics on outboard and sterndrive engines. The probes eliminate the need to strip wire insulation, making testing faster and preventing damage to wiring harnesses.
