    Hi everyone , I have a 2011 z1000st which I think has a charging problem , at idle the battery voltage is 13.4v
    But when I increase rpm to 4000 ,the voltage drops to around 13.1,so I'm thinking the regulator rectifier has packed up ?
    I need to to do some tests on the the regulator,but I don't know where it is located ,I'm waiting for a manual coming ,but would like to at least gain access to it asap

    On my 2015, the reg/rec is behind the left hand fairing panel.
    I would imagine yours is the same.

    Make sure you've got a known, good battery before fannying about with diagnosing the charging system.

    I have just put a Shido Lithium Battery on and tested again here are the results

    Idling 13.48
    4000rpm 13.7
    Main beam at idle 12.9
    4000rpm with main beam 13.7

    Manual says.. regulated voltage output 14.2 to 15.2
    I'm getting nowhere near those voltages

    well i'll close this one off by saying i done some tests and stator is fine and in spec , rectifier is fine and in spec , but the regulator isn't regulating properly
    ordered a replaced from Fowlers £145 .....ouch !!!
