We have a 2005 Winnebago Journey. Even when the motor home was new the chassis batteries would lose charge and have to be recharged every 5 days. I can't figure out what is draining them. Can anyone help?
Whatever it is, it shouldn't be going down that fast and certainly not if you're plugged in and the converter is meant to charge the chassis battery as well. Given as that might be the problem then you need to put a trickle charger on it.
Either way, you should probably pull one of the term. connections off and intermittently touch it on it's post to see if and how much sparking you might be getting. This is an indication of the size of the load being put on it and if all else fails, then start pulling fuses until this phenomenon disappears. This way you'll at least know where the culprit is.
