Also, any thoughts about hooking up a battery maintainer while the RV is just stored or how to help the house batteries last longer than a year. I think this is all that this set lasted for.Re: Trouble with Auxilary batteriesSo I checked voltage and I have 10.46 on each of the batteries. Sounds dead, right? When I turn on one little ceiling light and the little porch light it drops to 9.95. However, when put on the battery charger (completely out of RV) they appeared to charge easily and indicated a full charge. (Obviously not correct). As a point of reference I checked the engine/chassis battery and it read 11.88 without the vehicle running. Does this give everyone some ideas of what might be wrong? I really appreciate your help. Thanks!Re: Trouble with Auxilary batteries Sam Spade wrote: 3 in the RV wrote: Is this normal for it to be running all the time or did that indicate I problem I did not recognize? Yes and no, in that order......probably. The battery charger needs some air circulation, more so when the ambient temp is high. YOU NEED A MULTIMETER TO CHECK VOLTAGES. Without that, nobody can help tell you if you have a problem or not. OK I checked voltage and I have 10.46 on each of the batteries.

In off position, converter charger is disconnected from house battery. One time this past week I did got out to the RV, just stored in our driveway now and the "fan" on the converter seemed to be running non-stop. At that point I was plugged into shoreline and the disconnect switch was ON. Is this normal for it to be running all the time or did that indicate I problem I did not recognize?Re: Trouble with Auxilary batteries Crazy Ray wrote: Get voltmeter and check voltage. Google 12volt side of life, read and learn This is great info on here. Thank you so much!Re: Trouble with Auxilary batteries cencerrita wrote: You say you have power from batteries for lights but not enough power to turn the generator over. Just because the battery has a full charge does not mean it has the capacity with modern batteries. Get it checked with a load tester which any auto shop will do for free. This is a common problem with cars now and modern batteries. You drive home and battery is fine, stop the car and there is not enough "umph" to start again as battery has died. Thanks. I will do that this weekend and report back.Re: Trouble with Auxilary batteries twogypsies wrote: Do you have a battery disconnect switch on your RV? Yes I do. I Understand that I am to leave that ON at all times and just turn off for long periods of storage. Is that correct? What about when I am hooked up to shoreline for a month at a time, should I leave it in the ON position? Thanks!Trouble with Auxilary batteriesCan anybody help me with this? Problem: Auxilary batteries do not seem to be putting out energy despite the fact that they are fully charged. I am not able to start generator from auxiliary batteries. I am able to start it if I start the engine first and then start the generator so the generator is not the problem. Steps taken: • Auxiliary batteries disconnected and charged to full capacity with external battery charger. Charger shows they are fully charged • Batteries put back in RV. No corrosion on posts and water levels are good. • Control panel still shows batteries are dead. • Batteries do not have enough power to turn over generator. • Batteries are able to run lights in RV. • Solenoid was replaced in 2014 ---could it be this again? Thanks so much for any help or input.
