I have a Braun Entervan with a folding ramp. I was told that the ramp, door, and kneeling system all run off of the starter battery (I have no AUX battery). That sounds crazy to me, but whatever. Recently my ramp started retracting really slow and sometimes dropping back down after getting 2/3 of the way up. A few times I had to use the "ramp fold" override switch to pull it in. Here's what I don't understand:
Why does my ramp fold up slow (or not at all) with the "auto fold" button, but folds up fine with the override?? Both are using the same battery to function.
Also, I was thinking about using a good deep cycle battery as my starter battery seeing as how it runs quite a few aux functions. Any suggestions on battery brand/type?
