Possible battery or starter relay with Triumph Bonneville T100 (2003)

Hi,

I have come to get my bike out for the summer and discovered that the battery was flat. I have re-charged it, but the bike will not start. The ignition lights come on and the indicators work, but the headlight will not come on. When I press the starter button there is a loud clicking noise, which seems to be coming from the area of the starter relay.

Is this a battery issue because it has not re-charged sufficiently or could it be something else?

Cheers

Have a listen to the first 30 seconds of this video.
Good example of a dead battery - this one had been recharged, but couldn't hold the charge

If the battery is three or more years old, just replace it. I wouldn't even bother with the rest of the diagnostics, although you can try the jump start as rweb says.

If you haven't replaced the regulator-rectifier with a MOSFET unit, do that along with the new battery. The OEM r/r slowly goes bad, and it winds up shortening the battery life.
