Secondary battery wiring

[Ed Cheung]

I have this Kit for the a secondary battery, but the provided wiring diagram only show the wiring for the 2 batteries, for the connection to the alternator, is it to any battery is going to be fine?

The second battery is charged when the split charge relay closes the connection tieing it into the primary battery. On the national luna kit i know it waits 5 minuted for the primary battery to charge before closing the connection and charging the second battery. That way the starting battery is fully charged to re start the car again. if you tie the second battery to the alternator you created a second circuit permanently tied to the primary and thus bypassing the isolator.

So the connection from the alternator to the primary battery will wire normally and just add this wiring to the secondary will be all set

It is a RHD vehicle so, it is on the other side.
