Diagnose motorcycle battery without multimeter: audible and visual signs

5 signs of a dying battery

1. Slow starter that barely cranks
2. Click-click-click only (low solenoid current)
3. Headlights dim heavily during starting
4. Dashboard flickers off during starting
5. Cold start fails but warm start works

Headlight test (no multimeter)

Lights on, engine off 1 hour. Watch for 5 minutes. Visible dimming = battery failing.
