5.1.1 Battery connection
Here below you will find a series of diagrams how to connect the batteries in case that it is necessary to use an
auxiliary battery or in case of a twin engine installation.
The alternator should charge also the auxiliary battery without having the auxiliary battery getting discharged by
transferring power to the engine battery. Use either a battery selector switch or a diode splitter to achieve this.
