Possible Inverter Failure Or Just Old Batteries

[tkyiawild]

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?

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.

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.
