Lisle 50850 Ignition Spark Tester
The Lisle 50850 checks ignition spark with a compact test assembly. It is a spark-checking tool rather than a scan tool or compression tester, so use it to support ignition diagnosis without treating the observation as a complete engine assessment.
Specifications and included details
- Ignition spark-tester identity, model 50850.
- Standard and electronic ignition applications identified.
- No external power product description listed.
Before ordering
Confirm the engine's ignition arrangement and use the manufacturer's testing procedure. No universal coil-on-plug adapter inventory or calibrated spark-voltage measurement is established here. A visible spark alone does not prove ignition performance under every operating condition.
