Description & Documents
The Calterm Tru-Spark Ignition Firing Indicator quicky and accurately tests DIS and other ignition systems for the presence of secondary voltage without piercing or removing spark plug wires. It is great for trouble shooting "no-starts". The sensitivity adjustment dial allows isolation for a specific plug wire and eliminates false signals from wires routed in close proximity.
- High visibility 360 degree indicator
