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 Jimnibob
Since you hear the click, I would check the volts on the battery to make sure it is fully charged. Even though your charged it, it could have a 'dead' cell or it could be to weak to start the bike. Depending on how you made the connections to charge it, you may have blown a fuse or fried some other part, but it really just sounds like a weak battery. Also, make sure the kill switch is in the run position.
Thank you. Will it be the starter relay I can hear clicking? If so, I am assuming the fact it is clicking means that it is OK.
I don't know. You will have to listen to where the sound is coming from. It could be a relay or the starter motor starting to engage, but not having the power to actually turn the engine over. If your battery is more than ~5 years old, I would be highly suspicious of it, and verify the voltage first.
The starter relay is behind theh RH side cover. It clicks audibly when energised. As others have said, the overwhelming probability is that the battery is shot. Try jump leads from a (non running) car. That will prove that all else is in order. The lack of headlight illumination suggests nominal voltage but zero amperage.....a dead battery.
Is the pump priming? https://www.thetriumphforum.com/thr...art-try-running-through-this-checklist.12935/
I agree with the weak battery, but be sure to check that kill switch. Who among us hasn't learned that lesson? Good luck!
Sounds like battery to me for what it's worth, relay will click even with discharged battery. How old is the battery, not the bike?
I'd definitely change the battery, with many modern bike batteries once they've gone flat they never seem to take a full charge again. I don't know if Bonnies are susceptible but I have heard attempting to run the bike with a duff battery or jump starting from a car can cause damage to parts of the electrical system.

Easiest way to determine the battery goosed is drop test it connect your multimeter if you have one then load it up turn all the lights on and press the start button if the volts drop out then you know its a dead cell.
Batteries that just sit will discharge (totally normal) but are actually damaged over time. Recommend to always use a maintenance charger while the bike is not in use if possible. I use a Battery Tender Junior and my batteries have always lasted many years.
