Class A starter battery, leave on or turn of when staying?
We do have a class A and we do have a slow drain on the engine battery which I haven't been able to isolate.
At first I thought it was just the battery. We had just bought our MH so I wasn't sure - as the previous owner said it was a brand new battery. But not only was it not, he also failed to mention the slow draw.
So the first "fix" I did was to run a short piece of wire from my solar charging switch to my engine battery as all the batteries are under the same step, so that was easy and it helped me top up the battery enough to get started. Basically I just switched the solar from the house batteries to the engine battery over night and it fired up fine the next day.
However I still am not able to find the source of the draw, so the second step I did (after I killed my brand new battery) was to get a marine style power cutoff switch and installed it by my starter battery so that I can easily isolate and save the battery. Now when we're parked for more than a few days, once we're parked, level and slide is out, my next step is to turn the switch to disconnect the battery.
