Liana Posted January 11, 2022 Share Posted January 11, 2022 2018 LE2, #333 I've searched the FB pages and Forum, and do not see this specific issue, so I did look first! I only know enough about this electrical system (or any electrical system for that matter) to be dangerous. so I'm no good at extrapolating the information that is already here. My apologies if I'm causing you to roll your eyes! Our trailer is stored where it is plugged in and receives 2 hours of charge per day. Went by today and found the batteries at 12.0 volts (during the non-charging part of the day) Turned on the power, display jumped to 14.3, which as I understand the chart in the PD manual, is normal super boost mode, then later dropped to 13.6, also supposedly normal. EMS was displaying E0, 60 H, and 112 (volts I assume) that dropped to 111 before I was done in there. I'm at a loss as to why the batteries discharged to 12.0. (I did pick up from the Forum I think that I need a bigger ga extension cord and no longer than 25 feet) So given the above, I'm stretched to understand why when I turn the power on, all seems normal (maybe except the 112 v? maybe should be higher?) but loss of charge over time. The trailer is in storage, but not fully covered, solar should be picking up at least some charge over time. There should not be any parasitic draw, nothing is on (I did turn the Main Cabin lights on when I went in there, but nothing was on before that.) I'll be grateful for insights, I know there are a bunch of electrical wizards here! 1 2018 LE2 #333 "the Otter" 2015 Silverado 2500HD Link to comment Share on other sites More sharing options...
