Latest update.
We went camping over the weekend up on Lake Chatuge. It was pretty hot and the fridge compressor was on more than usual --- almost like the NC Overland Rally/Workshop.
I measured 12.6V on the batteries when we left; with about 2.5 hours of charging off the 180 amp alternator on the way home, they were back up over 13V back in the garage.
I have the fridge plugged in on the D/C circuit and A/C so that it switches when the charger is plugged in. Got home and plugged in the shore power; the Elixir charger started to beep again, signalling failure. It's only supposed to beep as a warning if the D/C circuit is overloaded.
I emailed Scott, he said he was sorry, and he's going to send a different brand of charger.
Also of note. The nylock nut on my Max Coupler got loose and the hole on the Max is elongated. I have to contact Martyn and let him know. I need few new parts and will have to use my lunette & pintle for a while.
