So i bought a charger and put a full charge on the battery. Still no dc power. Checked inside fuses and breakers, nothing. Saw a fuse on the exterior, near the battery and it was blown, replaced and all appears ok. I have had a battery tender on it for two days and it is holding charge. Obviously the large draw is gone. I assume this fuse must have blown somewhere w the second battery and must have kept the battery from charging w the converter when the generator was running. Anyway all seems ok. Will not be messing w the emergency trailer brake again.
