I'm on my first trip in my new-to-me 1989 SMB.
I'm pretty sure I have a house battery that needs to be replaced. It took a charge when plugged in at home on shore power but quickly ran down and now doesn't want to come back up to above 12v while driving, even for extended periods of time.
The first night sleeping in the rig the only thing drawing from the house battery was the fan for the furnace, I had it set really low so it wasn't kicking on very often. In the morning I noticed that the house battery was down around 11.5v. I had suspected I'd need to replace the house battery so this wasn't that big of a deal, the previous owner had let it sit for 2 years without any kind of charging device on it and without driving the SMB.
What was more of a problem is that it also seemed to draw down the starting battery. It barely started that morning.
I had been told by the PO that they were "separated" but he didn't go into specifics of how and I'm just now learning about all this stuff so I wasn't exactly asking the right questions.
I don't see anything that looks like a separator but I'm also not sure where/what to look for.
I do have a Xantrex panel which looks just like this:
As I was told, originally SMB spec'd 2 batteries under the hood, one for starting and one house. My SMB has since been upgraded with a much larger house battery under the seat. The PO was kind of vague on the details but I think he said that the house battery under the seat and the house battery under the hood are connected and are separated from starter battery. Unfortunately that doesn't seem to be the case. Does this sound right?
Unfortunately I don't have my multi meter with me but when I get home from this trip I plan to start poking around, I'm just not entirely sure where to poke.
Thanks,
Dan
