Thanks Myron for the input! I will perform the tests you mentioned when I get back up and running. Meanwhile here's a picture of my driver's compartment. Looks like someone replaced the OEM Isolator Delay Relay and mounted it to the side wall. Not sure why they didn't go back in original location. Also here's a better picture of my passenger side compartment.

Thank you Tom for all your input! I will definitely be ordering up 2 Blue Seas disconnects. My OEM Domestic switch is sloppy and I get a 2 volt drop when wiggling it! So I would feel better starting fresh with 2 new disconnects. I do have a 2004 wiring diagram that came with the coach from the previous owner. I don't think my coach has the BIRD system, that area in the rear passenger bay is empty. But it looks like someone replaced the Isolator Delay Relay in the electrical bay under the drivers window. If I understand right, that one is one directional and not bi-directional like the BIRD unit. I saw a good You Tube video from AZ Expert and he shows how to add a BIRD in the front drivers side elec bay. Looks like I could add it to the rear passenger bay easier and it would end up matching the 2003 wiring diagram. I will add a couple better pictures of passenger rear and drivers front electrical bays. Thanks again for your help!

Thanks for the input vito! I have seen a few write ups on the Blue Sea and it looks very cool. But from what I understand I would have to manually open the Blue Sea isolator via the combining switch when/if I ever have 2 incoming charge sources (generator, alternator or shore power) at the same time. Is that how it works? I'm afraid I would forget and overcharge or damage something. I think the Big Boy opens automatically when 2 sources are detected, but I'm not positive.

Hi, brand new (to me) Windsor owner here! During my inspection of the coach (before purchasing), I noticed the chassis battery disconnect had been removed and both cables had been bolted together and taped up. The seller convinced me that the OEM disconnect had gone bad from heat and loose contact and been removed/bypassed. I kinda overlooked it and figured it would be a simple repair by just adding a new disconnect. Fast forward 3 days.....got the coach home, but hasn't been plugged in since we got home and I go to start it and both sets of batteries are completely dead. After some closer inspection I noticed that the battery isolator relay is connected incorrectly with both battery leads (house and chassis) connected to the same relay stud. Further inspection reveal melted chassis cables near were the disconnect is supposed to be. Any suggestions on where to start with this repair? Anything else I should check? I already knew it needed house batteries so I'm planning on those along with 2 new disconnects and most likely a new isolator relay, maybe go with a Big Boy. I'm hoping that will get me back up and running. Thanks for any input!
