So the solution to whatever parasitic draw you had (I remember some thread about battery going dead but not the details) is the dealer put a disconnect switch on the charging line from start to house batteries?
You should have your dealer explain what it does for you and how to use it. Or better yet , figure it out yourself. That way you’ll remember since your issue was recent, you should understand what the band aid was that was applied to it.
Need to have a bit of basic aptitude about the thing you’re trusting to get you in and out of the back country and live in.
