Random starting problem

[darrsi]

Old battery


12.4v off
12.58v with engine and headlights on
Didn't test with headlights off
12.6v when engine turned off


New battery


13.1v off
12.75 with engine and headlights on
14.1v with headlights off
13.15v when engine turned off


These voltages were measured with the bike just ticking over, both times for around 3-5mins.


Hopefully the old battery was just getting a bit tired and the new one will sort things out.
I always ride with both headlights on, but now know to definitely have them switched off when starting the bike.
