Yanmar 3YM20 circuit diagram

We have recently had a Yanmar 3YM20 diesel engine installed in our Westerly Centaur. Does anyone know where I can get a circuit diagram for the engine wiring loom? I am finding this difficult, and we need to insert a splitter into the alternator output in order to be able to charge both batteries (auxillary and starter) without actually connecting them.

you do not need a wiring diagram for that. just put the splitter in the main positive output from the alternator.Do not forget that you will lose voltage across the splitter. It is best to fit an alternator regulator that senses the voltage at the domestic battery at the same time as fitting the splitter!
Good luck
