If its remote sensing then could a high resistance on the sensing circuit cause the alternator to ramp up?
I think it means the regulator is spot on (14.4V is what it is aiming for). What it may mean is that 0.4V is lost between the regulator - and earth somewhere - more sanding of old connectors! I find earth issues are a common problem with old Land Rovers, not helped by the electrolytic corrosion where aluminium meets steel.The voltage between regulator + and - (also under full load) is 14.4v. But still not sure what that means from the Lucas manual notes!
