Our lead acid batteries were new last year. They were in the garage all winter and were on trickle charger. I put them into the Oliver and connected the thick cables on which go to the inverter, and the smaller cables which feed the DC circuits. The inverter works fine using the batteries to provide the AC plugs. None of the DC items are getting any power such as lights, water pump, jack, etc. There is a breaker under the street side bed. There was a wire on it that had a 1 amp fuse in the line. Replaced it with a new fuse. Still not getting DC power. There is a red button sticking out of the breaker housing and I can move it in and out about 1/4 inch. I also checked the two green, 30 amp fuses on the DC panel. OK. Never had this problem during the last 10 years we’ve owned it. Does anyone have any experience or similar problem?

I had the same issue with my 2015 Oliver Elite II. The tow vehicle was not charging the battery. We were on a month trip out west when we discovered this. I got a plug diagram and checked the tow vehicle battery charge and was OK. I checked the ground lead at the plug and it had continuity to the truck frame. Between the battery charge and ground was 12 volts, proving that the tow vehicle was not the problem. I then checked the mating connections on the Oliver plug. I discovered that the ground connection at the plug was not grounded to the trailer frame using the multimeter test. I disassembled the plug and checked all the connections. All was OK. I then traced the ground wire from the plug all the way back to the grounding bar beneath the rear dinette seat and found it not connected. It just continued to the rear of the trailer. After the trip, we took the trailer to Oliver for some other issues and to correct the charging problem. They told me the problem was in the tow vehicle and asked me to bring it in so they could check it. They did the same checks that I did and agreed with me that the tow vehicle was OK. I went inside with the technician and asked him to show me why he thinks the trailer is OK. He showed me that he had 12 volts between the battery lead and the trailer frame. That's because he's measuring the voltage across the battery terminals. I asked him to check the voltage between the battery lead and the ground connection in the plug and it read zero. Then we checked continuity between the plug grounding lead and the frame and it showed none. The ground lead coming from the plug through the trailer was NOT connected to the grounding bar. The technician said that during manufacture, it is cut in two and both leads are supposed to be on the grounding bar terminal. He made the fix and we always have a charged up battery when we get to our destination. Oliver makes a high quality product and something as simple as this should have been caught before it left the factory. A little bit of quality control testing of all circuits would have caught this simple mistake.
