Anyone got a wiring diagram for a duel field alt and regulat

Hi, I'm in Australia and have wiring problems on a '69 Barracuda. Someone has fitted a later type dual field alternator and the late type regulator but the wiring is everywhere. It has already taken out one regulator and I don't know if it is wired up wrongly or if it's just died from old age.
I've got another regulator on it now and it seems OK but I'd really like to check the wiring, any help would be much appreciated.
Thanks
