Coach batteries replacement
Hi, I'm a very new member and hope I am posting this in the right place but, here goes. I have a perplexing problem with our 2005 Itasca Meridian re house batteries, in that all DC circuits in the coach seem to work fine (lights, sliders, etc) but I have to have the engine running to be able to start the generator. My assumption is that we have one or more weak house batteries (there are 3) which can't accommodate the starting load for the diesel generator. I'm thinking about replacing them before our next trip which starts next week which leads to my question. Because I have 2 new six volt deep cycle batteries from another project, I would like to save some money and use these in series as was the configuration in 2 of our previous campers. I would appreciate any comments or advice.
