Hi folks,new to this so persevere please,I've got a cbr1000fv that will charge the battery at 14.8v but will only manage 11.9 with the lights on,any ideas.

 

I would say your battery is buggered.

 

Thanks peeps. Probably gonna have to lean on you for a while.Bike not charging with lights on?

 

The current draw (amps) is more than can be supplied by the battery and charging system (alternator/voltage regulator). Try these, a video and then a few fault finding flow charts.

Hope that helps, but keep asking questions. That's what we're here for.
