Hi @Crusty181 , the module that you are modifying was what I was talking about in November 2018, when @Drover bought up the subject of how to provide an electrical system to protect battery/ies from low voltage , better than the Setec or other systems which had very low (poor) voltage cutouts. I still have mine and showed it to @mikerezny when he was up here in Queensland a few months ago. I tested my unit on a fridge battery too and it did exactly as programmed, cutting the load when voltage dropped under the setting, and re-connecting a few seconds after cut-in voltage was reached as battery charged. . For under $10.00, it comes in its own semi sealed module which you can fit into hole in the wall etc. You can vary LVD and LVR over a wide range and it can handle 20 amps too. And you do not have to be an electronics tech head or make holes to poke through cover to make adjustments, or polish anything as the LED screen is easily seen on the front of unit. See the link below.
Incidentally, 12.0 volts seems fair enough for a LVD, and I can understand why you are setting the LVR at 13.0 volts too, as your modern Troopy may not produce that much from the latest alternator at times. See attached from Red Arc.
Be careful when riveting PCB to anything - they are brittle and the printed circuit is easily cracked. For $10 already made up, you could save your self a lot of hassle. Good luck.
