Charlie, Based on your measured values, I’d first look at the battery cable to battery post connection(s): 1. If the 12.7 volt measurement was taken directly from the battery posts, then the battery is not dead. 2. The solar directly feeds the battery via the Zamp controller. It does not pass through the inverter or the main battery breaker. So the 11.7 voltage read from the Zamp controller is more likely a voltage drop through the battery post connection(s), not the main breaker. 3. The inverter also shows 11.7 volts, with no load, so it could also be reading a voltage drop through the battery post connection(s). That’s a reasonable analysis, and battery post corrosion is a common problem with AGM batteries. Sometimes the lead battery posts become oxidized. Although they appear fine, oxidization is a poor conductor. Having said all that, you possibly have a different setup or a poor main ground connection. Some simple voltage tests at various connection points would quickly isolate the problem if cleaning the battery posts does not fix the issue. Hope that helps. Cheers, Geoff

I added the SS fender washers like @DavePhelpsdid. I later changed them out to black SS fender washers from McMaster Carr. Bill Hull 313

What is the voltage measured directly on the battery terminals with a DVM?

I'll add our two cents. We've had our new-to-us Ollie for 18 months or so and are still finding stuff we think we need. We moved from a truck camper to the Ollie and thought we had most of what we needed, but.... As @FirstApex mentioned, I suggest a LevelMate Pro (so you can power from the Ollie): https://www.amazon.com/LogicBlue-Technology-LevelMatePRO-Wireless-Leveling/dp/B01FGGSWPW/ TPMS system to monitor the tires (you'll need metal valve stems): https://www.amazon.com/TST-507-FT-4-C-Repeater-Temperature-Monitoring-System/dp/B08W3QZ499/ Induction countertop cooktop and induction compatible cookware for inside and outside and many people have grills (Blackstone, Weber, etc.). We have a Paclock hitch lock (similar to the Proven) and a Collar lock to secure the latch (if you have the Bulldog coupler). https://www.amazon.com/PACLOCKs-UCS-77S-BUL-2516-Trailer-Coupler-Integrated-Stainless-Steel/dp/B0DLLQPB15/ or https://www.amazon.com/Proven-Industries-2516-Heavy-Duty-Couplers/dp/B0G319Y11G/ https://www.amazon.com/Collar-Trailer-Bulldog-style-Couplers-Including/dp/B00HL2NM0K/ You'll want an Electrical Management System (EMS) for the campground power post (in addition to the onboard EMS), a 30 AMP circuit tester and a non-contact voltage detector and outlet tester. https://www.amazon.com/gp/aw/d/B01N0W4CZ8/ https://www.amazon.com/Progressive-Industries-Receptacle-Tester-Black/dp/B088CWBBBM/ https://www.amazon.com/Klein-Tools-80025-Non-Contact-Voltage/dp/B0912Z1W88/ Don't know what hitch size the Apex comes with but I'd ask for the 2 5/16" coupler. There's lots of info on the forums. I suggest using @Wayfinder's search tool found on this post:

GJ, You are correct on all counts! Good logical thinking, and good luck with the yellow wire mess! Geoff

Unhelpful Update: we just arrived home, and everything works again. 🙄 We’re starting a barn build tomorrow (unfortunately not for Curiosity due to allowable square footage), but when I get a chance, I’ll track down what has to be a loose connection. Thanks for the help, and an update will follow as more information becomes available.

Steve, cool vid. So glad to refer you to Easton at Inverter Services and he got you all taken care of. He handled all your upgrades exceptionally well. As previously post, Easton installed the same outstanding and comprehensive Victron system on XPLOR Hull # 634 after we returned from our 54-day trip to Maine last fall. Nothing like a super clean professional upgrade/install. I highly recommend Inverter Services and Mr. Easton sure knows his way around Olivers!

For those that have never had the chance to see the interior of the Outlaw Oliver, be sure to look around during this short video. Steve and Tali have switches for switches and extra "lifts" for the beds that increase storage room a bunch. Bill

Also - do you have solar panels? Do you have a solar panel cut-off switch? do you have an inverter? Is it on or off? do you have a fridge that runs off DC power (i.e. a three way fridge)? If yes then what setting is the fridge on (a/c, d/c, or propane? Bill

More info please. Type of batteries? What voltage do you see when you press the Battery button on the SeeLevel monitor? Are you plugged into shore power or running off batteries? Do your interior lights work? Do you have a multimeter?
