Battery Problem

Hiya Guys/Gals

When i put my lights on they seem to drain my battery as the day after i cannot start my bike

Also my lights get dimmer when on long journeys

I have replaced my battery and have taken the following readings:

Fully Charged 13.17V
Battery at 5000 revs 15.15V
Idle 15.24V

I have not done the tests with the lights on yet though

I appreciate your help

Cheers

15.24v sounds a bit high. Get these measurements

Engine off Volt
Engine idle V
Engine 5k V

Lights on Idle
Lights on 5k

Curvy, or pointy?
Could be Regulator/rectifier. 15v does sound high, should be in the 14s when revved to about 3 - 4000rpm
Tick over should be in the 13s

Sounds like reg/rec but give your connectors and earth a check over.
Have a look through this electrical diagnosis guide http://www.electrosport.com/media/pd...ng-diagram.pdf
Or have a read through my thread here http://forums.sv650.org/showthread.php?t=164281

i think it is the R/R to be honest

It is a Curvy mate

just done the readings again today and was shocked

Engine Off 12.34V (Bearing in mind not been charged for a couple days)
Idle 18.01V
5000 RPM 19.04V
Lights on at Idle 10.31V
Lihts on at 5000 RPM 13.2V

cheers again guys

Take the RR out and kick it across the field!
