The BIRD has a spade lug with the green wire carrying only the coil power of the relay. Incidentally, i replaced the Trombetta with a White Rodgers 200 amp solenoid that has much lower coil current. Nearly an exact replacement for the powe hungry Trombetta.

That's basically what I was going to do in my Axis, except put a switch in there, and in your case with a large battery bank and 100 amp charger, I think that is an excellent idea. In my case with two small 29 batteries in my house bank and a 55 amp charger, I don't think that is necessary. Your replacement of the Trombetta with the White Rogers solenoid is an good idea. I will put that in my list.
