Hi Neils
I've posted a pic of what our alternator looks has been modified for an external reg but the originla reg is still there.
You can check if the alternator is isolated with your multimeter on ohms...between the negative alternator lead and the engine block, the resistance should be large, if it is close to 0.00 then your alternator is not isolated.
