Thomas Spagnoli: workshop approach for Royal Enfield Himalayan security interlock allows crank but disables fuel

My workshop rule for Royal Enfield Himalayan security interlock allows crank but disables fuel is simple: prove the basic condition first, then decide whether the clever part is actually needed.

1. Start with model, year, mileage, engine type, recent work and the exact symptom.
2. Separate opinion from measurement: voltage, pressure, compression, plug condition, code history and visual evidence.
3. Make a small checklist and tick it off in order. It is slower for five minutes and faster for the whole repair.
4. When in doubt, return the machine to a known baseline before tuning or modifying.

If the result changes hot versus cold, or under load versus idle, write that down. Those conditions are not noise; they are clues.
