I am trying to fit a Sterling regulator to a Paris Rhone Alternator model
A13N1M on my Bukh 20
it has 4 terminals on the back -ve and +ve which are self explanatory, and W and 61 which I believe are Rev Counter and Ignition respectively. However I do not know where to fit the "field" wire to the alternator. I have spoken to Sterling who have been helpful but the only way they can be sure is for me to solder some wires into the regulator and run the engine up with a multimeter across them - this I would be happy to do normally but at the moment the cooling system is half way through refurb And I would like to get this job done. Does anyone know has any one fitted these two together before?
many thanks for any help
