    Aux Power Locations on Z900 - Switched or not?

    As the thread title stated, does anyone know if the aux power leads in the front and rear are switched with the ignition or if they are always on (tied directly to battery)?


    Thank you.

    They’re all switched. You can test them with a pair of wires to the horn though. That’s the easiest 12v thing to get at with fly leads.

    Thank you.   :821:  Thats what I needed to know.  I misplaced my electrical diagram and am not near the bike but am designing a circuit for it sight unseen.

    Yup, found my manual and confirmed.  Switched with the key and is tied to a 7.5A fuse.  (At least on the 2020) 

    This simplifies circuit design as it eliminates the need to install a relay to be sure accessories are powered off when the key is removed.

    Maybe I'll create a latching circuit/ no volt release so that I will never start the bike with aux lights on to prevent drawing ampes when starting.... :084:

    EDIT/ ADDEMDUM: The switched leads are active as soon as you start to crank over the engine.   If you have any high current draw accessories hooked up to it, I recommend that you make sure they are off or are on a no-volt release circuit.
