This is an issue that we've been dealing with for over a year now, with the morons at Camping World. I'll try to sum things up as concisely as possible. It's a 2008 Itasca Latitude 39W. New chassis battery, as well as 2 new 12v house batteries. Solar battery charger installed.
June 2022, no problems with electrical issue at all, demonstrated by 2 camping trips. RV goes in for unrelated warranty work. Go to pick up, and the chassis battery is dead. Don't think much about it. Hook it to shore power at my house.
July, notice that something is draining the house batteries, as well as the chassis battery. RV goes back to CW to have it fixed. Sorry, but I don't recall what they "did". Take it home. Same problem, again.
Take it back around Aug of last year, again. Stays there for 4 damned months. They say they fixed it; again, I'm sorry, but I don't have my records in front of me to say what they did.
Feb, this year. Same damned issue. Take it back to them. They replace all 3 batteries, again. They removed some sort of aftermarket component that they said was the problem. Take it back home.
Kept off of shore power to test. This time, it took 3 days for the chassis battery to be fully discharged. I know VERY little about electrical systems, but here is what I do know:
* 3 new batteries. The problem drains the power from the house batteries, as well as the chassis battery; noticed in as little as 8 hours.
* Factory battery disconnect will alleviate the issue; but I don't think I can start the generator with that disconnected.
* Battery will be still be drained when connected to shore power. Don't know how long it will take. Last time noticed was around 1 week.
Anyone have an idea of what could be going on? This is driving me crazy, and is seriously screwing with our enjoying a rather expensive item.
