'06Beo500GT, 21kmiles. No starting problems till now other than replacing battery and r/r with a mosfet about a year ago . Started fine last week. Turned key on this morning 9am, 50 degrees out, all dash lights came on as normal, showed 13.2v, hit starter button but only got a brief, single click sound, then dash lights went off except for the oil pressure and efi lights that remained on. Tried it several more times, same result. Side stand up, left brake lever engaged, kill switch off.
Garage kept, battery 1 year old and kept on battery tender. Was thinking might be the relay as have seen some written in this 500 forum about bad starter relays and replacing them with auto relays.
Went back out this afternoon and it started just fine. Started it up several times just fine. What gives? Would those symptoms seem to point more to starter relay or starter solenoid? If either relay or solenoid, do they tend to die slowly over time or just die all at once? Thanks for any ideas. As for electrical diagnostics, I am a poor electrician so would help me much to know what I should just go ahead and replace so it is dependable since I would have to remove all the plastic to get to either of those parts?
