Hi guys need some help , my ped keep running the battery flat but only when the lights are used all threw the summer while we had light nights it was fine now the it gets dark early I started using the lights and it runs flat in 20- 30 mins checks the stata and and the rectifier/regulator they are working fine battery is fine holds charge untill the lights are on any help would be great cheers guys
If the bike is charging across the battery terminals at around 13.5v then stick a new battery on it. Probably got a dying cell in there.
