I didn't have much time last night for trying to solve my troubles so I got confused when I read in The Manual on page 48, "The chassis battery for the engine is not charged off the converter." but later in Appendix 11 a complete discussion of the BIRD etc states it correctly. I was in a rush.

Now I'm back from an out-of-town travel baseball day and have time to work on this. The first thing I did was update my copy of The Manual to the current version. (Thanks for the link JamieGeek! and super thanks to Ed for The Manual and updates!) I was using an outdated copy and the verbiage on page 48 has been clarified. So I do understand the system and mine is clearly not working correctly. So now to research troubleshooting steps. I think I'll start with the incorrect wiring. (Wishful thinking) I might not get too far however because it's now 37* outside with some snow. Brrrrr
In my 2016 Axis, the red wire coming out of the BIRD is supposed to be connected to the coach batteries. In mine, I never figured out where it was connected, but it was not connected to the coach batteries so the BIRD never received the correct voltage to tell it to open and connect the coach and chassis batteries. When I cut the red wire and connected it to the coach battery side of the Trombetta, the system worked as it was designed. May not be your problem, but might be something to check.

Thanks. I'm reading some of your old posts and posts of others while trying to come up with a game plan. I sure wish there was an easy way to get a meter on the wires going into the BIRD to check the voltage.

My Vegas is at my house hooked up to shore power. I just went out again with my volt meter (Did I mention it's cold and snowy? ) and the house batteries are reading 13+ while my chassis battery is 1. That's reading the voltages at the Trombetta and the same at the battery terminals. When the Emergency Start switch is held, the chassis side of the Trombretta goes from a +/-1 to a solid 0. I don't understand that. Could that be an indication the BIRD isn't wired correctly? Is there an easy/good way to measure the voltage of the red wire going into the BIRD without cutting it? Time for a think and another rum drink. On a good note I found the flashlight I misplaced last night!
