    Depends on the battery type and manufacturer. AGM batteries can be well over 13V when fully charged.

     

    As I say I have never seen it that high on a battery 

     

    I have had a fair few AGM batteries too! Yuasa and Motobatt etc 

     

    The only time I have seen a battery that high is either on charge or when just taken off charge and its settling down

    13V plus doesn't sound high. My bike is currently at 13.1V and hasn't been ridden for 6 days.

     

    I have never seen a static battery voltage that high its always been around 12.6

    You don't take the earth lead off the battery. You unbolt the earth lead at the frame leaving the battery connection intact. So you bridge the end of the earth lead to the frame. It's just often easier for access. 

     

    You effectively isolate the battery from the frame then remake the connection via the multimeter. So any current flowing will register on the multimeter. 

     

    Yes I know how to do it and how you meant to do it but your first post just said disconnect the earth lead and if anyone tells me to do that I would just take it off the battery :lol: 

     

    Just trying to make it clearer for the poster :thumb:

    Actually it has the HISS (immobilizer) system. Do you think it may have something to do?

     

     

    The HISS shouldn't drain the battery that quick unless there is something wrong with it 

     

    What sort of riding are you doing? lots of short runs? 

     

    Have you also checked to make sure its charging correctly

    Doesn't matter whether it's between the battery terminal and the earth lead or the earth lead and the frame, it just depends where is easier to disconnect. On many bikes it can be easier to get access by unbolting the earth lead at the frame and bridging there as battery compartments can be a bit tight. 

     

    but if you take the earth lead off the battery then go to the frame with the multimeter you haven't earthed it :lol: 

     

    Something needs to go to the battery to complete the circuit :D

    Disconnect the earth lead then put your tester between the earth lead and the frame. Set the tester to measure current flow.  At most there should be a few milliamps. Anything significant and you've got a current leaking. In which case pull the fuses one at a time until the flow stops. The leak will be in whatever circuits that fuse feeds.

     

    don't you mean between the earth lead and the battery negative terminal?
