2007 R1200RT-P 99k km
Symptom:Press start button 1st time and it is like a flat battery - just grinds to a halt. (No strange sounds like grinding, clanking etc.)
Wait a few seconds and in most cases, it cranks well and starts normal. Every now and then, it takes a few goes - again like battery is flat.
Observations:
- Hot or cold engine - no difference
- Weather - Tropics! Australia HOT, damn hot
- New Fullriver HC20 battery - cable connectors clean and good connection
- Swapped starter relay for another (second hand one I had from one of my previous BMW cars - same model) - no change
Thank you very much.
