Thomas Spagnoli: workshop approach for Kawasaki VN900 Classic battery has voltage but cannot make hot spark

With Kawasaki VN900 Classic battery has voltage but cannot make hot spark, the useful question is not 'what part is famous for this?' but 'which system stopped doing its job, and under what condition?'

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.
