well, previous topic dealt with my house batteries. turned out old ones were dead. replaced both, all was well. So day before heading out for Oregon i do some prep. began by retracting leveling jacks ...
If the batteries were hooked up wrong, there should be a circuit breaker or fuse that would have blown. Normally found on the ground right before attaching to the frame (I think, it's been a while since I've made that mistake). Also might be fuses on the back side of the converter.
