I'm disappointed in Thor for not spending the extra $50 to install a BIRD buy my lack of knowledge when purchasing the RV is ultimately to blame.
So, I'm going to install a BIRD (00362-100) and a new isolator relay since the old one is corroded pretty bad.
Also, I tested the Aux start switch after installing the fuse, and it works great. So the IRD is working as advertised, just not the way I want it to ��

Interesting. Learn something new every day. Didn’t know there was something pre-BIRD. Instead of buying a BIRD and isolator relay, I would consider a BIM 160 which is a BIRD and isolator relay in one unit. Costs about $200. I don’t know what a BIRD and isolator relay cost, but it probably is close. That is what I plan to do if my BIRD or Trombetta goes bad. You’re right to replace them. It’s nice to be able to plug in and charge up both at the same time. Especially if you Store for any length of time.
