Hi Everyone. Well, after 15 years the RV-Dreams Community Forum is coming to an end. Since it began in August 2005, we've had 58 Million page views, 124,000 posts, and we've spent about $15,000 to keep this valuable resource for RVers free and open. But since we are now off the road and have settled down for the next chapter of our lives, we are taking the Forum down effective June 30, 2021. It has been a tough decision, but it is now time.
We want to thank all of our members for their participation and input over the years, and we want to especially thank those that have acted as Moderators for us during our amazing journey living and traveling in our RV and growing the RV-Dreams Family. We will be forever proud to have been founders of this Forum and to have been supported by such a wonderful community. Thank you all!!
Is it the coach batteries or the engine batteries? Coach batteries should be charged from the converter if plugged in to shore power. Is the isolation switch open? Simple question, are the acid levels good in any of the above? How old are they? If original to the Alfa, it just might be time for new batteries (ouch). Like Mike said, check connections at the battery(ies) for corrosion. Shine 'em up. I helped a motorhome owner once, there was a tripped breaker on the charging circuit. It was a tiny black button on a little grey box with 3 wires. One of which was a larger guage wire to the battery. Might look around. Sorry I can't offer better help.
I have an Alfa See Ya. I had to replace all of the coach batteries at their 6 year life span which is more than I had expected to get out of them anyway. Instead of going with brand new batteries (big money) I chose to get re-conditioned ones that were about a third the cost. They came with a 6 months warranty and are still going after 2 years. Something to think about.
Dig out your owner's manual and start locating places were there might be an electrical issue with switches, fuses, breakers, and the like. As was mentioned, there could be a charging circuit issue. If there is a short circuit somewhere that is draining the batteries, you most likely will have to take it to a shop where there is diagnostic equipment.
Battery terminal corrison has always been an issue on my rig even when I take steps to put a protective coating on the terminals. As mentioned, check your levels. The starting batteries are closed cell so that's not an issue.
