tkyiawild Report post Posted June 19, 2014 My coach would not take a charge at a fifty amp service and would only trip the breaker.We did get home and are now trying figure this out. I tested the batteries and some are completely dead and I don't see purchase dates so I don't know the age. They do show signs of age because they are bulging on the sides and on top some. How does this play in to the coach tripping the breaker? Share this post Link to post Share on other sites
billbaldwin Report post Posted June 19, 2014 Sounds like you have a short in the system If the batteries are bulging they more than likely froze over the winter They could be old but if they froze they were undercharged. I would have a tech check your inverter. Share this post Link to post Share on other sites
wolfe10 Report post Posted June 19, 2014 With completely dead batteries, start there. If bulging, don't waste time-- replace them. If a battery has in internal short, it can be dangerous to attempt to charge them. THEN see if the inverter/charger works properly. Share this post Link to post Share on other sites
