Originally I did not realize I was running into the same flawed technology. I was really shocked when the battery was not only dead, but FLAT DEAD the other day. I did have a booboo a week before when the compressor stayed on all night, because we did not wire to be only engine on enabled unfortunately...but the trucked fired right up in the morning no struggle.( I guess I licked the air leaks) But maybe that little engine off drain killed the delicate battery design...Not good for off-road.
