Battery or charging fault? Curvy. - SV650.org

14-05-13, 05:47 PM

So went to leave work and bike turned over a couple of times then slowly died. I am confidently assuming it is the battery. I had a new reg/rec about 18 months ago but the symptoms when it broke down were completly different, on that occasion it died completely this time all the lights work and will attempt to turn when left for a few minutes.

Lucky one of my colleagues rides a Triumph Daytona so I rode pillion home.

Whats everyone else think?

Cheers.

No probs Davey

Have a look at my charging thread or the below quote from my thread as it might be of some help.

This was achieved by running a wire from the black wire on reg/rec to the -ve on the battery so it looks like it was a bad earth or wire somewhere

Is it safe to keep this wire permanently attached now as it seems to work?

How do these figures look, new battery fitted in the work car park and I get the following:

Ignition off 12.7v

Idle 13.8v

Do rev test with lights on at 5000rpm what volts you get then?

I did that it was 12.9v which according to that guide is fine.

Just checked the old battery I took off that is putting out 12.1v, does this mean faulty?
