This demonstration guide answers one field question about coil ground isolated by new paint. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with resistance from coil base to crankcase. That reading separates coil ground isolated by new paint from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the ground path as the primary path. If it is in spec, do not replace the ground path just to complete a parts list.
Repair the failed system
The usual correction is the ground path, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about coil ground isolated by new paint.
Stop before you make it worse
Do not adding a jumper to a fuel line clamp. That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the ground path is corrected, convert the visit to a broader diagnosis rather than stacking parts.
