I was looking at a way to hook the aux and vehicle batteries of the Westy together. I have a charger set up on the aux batt, so that it gets charged whenever the vehicle is plugged in. I would like to connect the two so that the vehicle batt can share in that charging when needed. Or let the aux batt boost the vehicle batt when needed. So I thought, there's already a relay in place to do this. How about a little switch to energize the coil on that relay? I tried applying 12V to the blue wire and that did the trick. So then I started to find a switch to install for the purpose. Now I am thinking about where that 12V is going to go when it also travels back down the blue wire to the alternator. Is this a bad idea? Thanks for any input. Edward |
