Pulled my battery this morning and noticed straight away that one cell (?) was a bit low, like, a good bit below the minimum level.
Topped that up and took it up to the flat to charge, the 'charging' light litr up straight away but after about 30 seconds the 'fully charged' light also came on and within the minute the 'charging' light was off and only the 'fully charged' one was on. Thought that was a bit strange but took it down to the bike again.
Checked it with the meter and got 12.5v across the terminals on the bench so all seemed good but bunged it in the bike and it wouldn't start. Bump started it and was getting 13.7v across the terminals at tickover so seems like the charging system is working? @Brickman, I can't find any wires coming from the area of the stator, will the be under covers and stuff?
So at this point I'm thinking, battery seems to be charged so what else? I checked all the connections around the battery and everything seemed ok so I started thinking, could it be the starter? Figured I'd try jump start it from the car and that'll tell me...something?
Jump leads on, car running, bike fires right up. So, not the starter motor then.
Back to thinking it's the battery. Process of elimination says that when I had an alternate source of power it was ok so probably the battery.
I've had the bike since May so I'm thinking that if the charging system was bad I'd have been having issues before now. Hence, bung a new battery in and it should fix my problem and not just get buggered by a dodgy charging system?
