    Depends on the alternator I suppose, I recall I did have a live feed to an alternator once, but I never removed the battery with engine running to find out. ????.

    The cars I did disconnect the battery, the engines kept running... 

    ah yes I see now, my sincere apologies, in the old days the 'excitation ' current was always sent to the rotor via a dedicated cable

    from the ignition switch. that circuit has changed now taking the initial 12v from the alternator output cable, which would receive it via the battery, but continue to receive after output is established , thus it is possible to disconnect the battery +, and run ok.

    get out of touch in my old years 55
