Also you might want to look for the BIRD. This is intellitec’s Bi-Directional Isolator Relay Delay ( BIRD )which offers a new approach to charging all batteries, house and chassis, I'm just not sure if 2012 they used this. So, now you have a couple of things to look for. Its a square box about 5 x 3, ok it's a rectangle box. Which have some heavy cable going to it.
