Alternator and regulator wiring | YBW Forum
I have a 24v CAV alternator (AC5 or AC7 I think) for various reasons I disconnected it and can't find my notes to reconnect the alternator to the regulator. It looks fairly simple, there are two large black cables from the alternator , marked "B-" & "B+" which I presume go to the battery and two smaller red cables which need to connect to terminal "A" and terminal "F" on the regulator.

CAV Type AC5 24V Alternator I recognize the alternator in your pics. It is an early seventies CAV Lucas Type AC5 24 volt unit. It is typically paired with the Lucas Type 440x (x=A,B,C or D) external voltage regulator, as indeed you also have. I have the exact setup in my Nicholson N32 sloop, with its original Watermota Sea Panther diesel auxiliary.

Wiring 24v charging system - Lubrication, Batteries
It has an AEC diesel with alternator, negative earth system and runs two 12v batteries. I think that all I need to do is run an earth from the alternator to the chassis and a positive wire back to one of the positive battery terminals.
