ok so i kinda worked out with 2x 2core cable going to a DPDT switch then to the car battery charger, when the light turns green flick the switch to do the other battery.
I was wondering if there was something i can put inline to relays instead of the switch where i hook to the the green led so when it turns goes it it flicks some sort of trigger to change to the other relay? 12v car relays.
any ideas.
Thanks
