    Hello all,


    I bought a 2018 Bobber Black last June with 5700km on the clock in Ireland. Absolutley love it.

    I've had my first issue yesterday. Went to take it for a spin aeround 20km or so but noticed it struggled to start. Almost like it stopped trying halway through and then started up. Thought it was odd at the time but didnt think a crazy amount about it. Then I noticed all the clocks had reset such as trip etc but the bike felt like it was running fine. Took it on the 20km spin with no issues and came home. Was going out again that day and the same thing happened. Clocks reset and hesitation to start. Drove it around 6km to my mates house and there when I went to turn it on it would not start. Lights came on but just a click.

    Push started it and the bike started for about 30 seconds, lights went out and then the bike died.

    Bike is garaged and gets out on spins alot so is not sitting around draining the life out of the battery. 99% sure its the orginal battery and there is now 9800km on the bike

    I wonder is this an electrical/altenator issue or is it down to battery losing charge regardless of the altenator/mileage.

    Can a battery die suddenly and just not take charged or does it seem like more of an altenator issue?

    Thanks for the help.

    Conor

    I would look at the battery first. Charge it, then start the bike check its charging. stop the bike check wether the voltage is dropping with ignition off, leave it over night see what he voltage is the next day. Or just replace the battery and see if that cures the problem.

    Batteries can die suddenly. Sounds a bit like a loose or damaged cable could also be the cause. If you have a test meter checking charging system is a minute's job :)
