This demonstration guide answers one field question about a repair that never confirmed spark dies on release. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with spark-stop on bail or switch. That reading separates a repair that never confirmed spark dies on release from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the kill circuit as the primary path. If it is in spec, do not replace the kill circuit just to complete a parts list.
Repair the failed system
The usual correction is the kill circuit, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about a repair that never confirmed spark dies on release.
Stop before you make it worse
Do not leaving a disconnected kill wire because it starts easier. That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the kill circuit is corrected, convert the visit to a broader diagnosis rather than stacking parts.
