Relay clicking rapidly…
I'm completely at a loss. Relays usually click rapidly because they're trying to come on, but there's not enough power to the electromagnets, so the switch itself keeps clicking back into the "off" posiiton before being drawn partly on and the electromagnet giving out again. A clicking starter motor because of a dead starting battery is the best (and loudest) example of this that I can think of.
But why the BIM would do that, no idea.
Batteries discharging with no known load…
How is your inverter/charger set? I've found out by trial and error that on my Interstate, it's possible to shut off the DC power at the disconnect, and still have AC power to televisions, refrigerator, and microwave with the inverter/charger set to "auto/invert" and the remote-control panel also set to "auto/invert." So, I now make sure that when I put my unit into storage, the inverter/charger is set to "charge only" or "off" as well as having the disconnect switched to "off." That's the only way I've found to power off ALL house systems.
(Note, power to the microwave just means the green lights on the panel come on for the clock, not that you can cook anything.)
Since I discovered that and always switch off the inverter/charger, my rooftop solar panel has not experienced any more problem keeping the house batteries at 100% charge no matter how long it sits in storage.
However, the carbon monoxide detector and LPG detector might still be on. I haven't checked those, but as safety devices, they might bypass the disconnect switch. I so, the draw is low enough the solar panel keeps up with no trouble.
I also had to add a small dashboard solar panel that plugs into a 12v
outlet to keep my main engine battery charged up, thanks to the drain imposed by my Viper alarm system.
