Hey John, this guy is OK. He's Matt Marcenelle, Retired Military, Wife is a retired Coast Guard Commanding Officer. Son just graduated from West Point. They live up in Pennsylvania and have had their Oliver 4-5 years. I met him the week he got his trailer. He called me this morning about this issue. It seems to be charging fine off AC but not so well off Solar. He did have his panels off earlier this summer for ceramic coating of the trailer. I told him to recheck his panel connections and if that didn't work to call Victron. I really don't think it's his batteries. He has a Xantrex converter/charger that I know almost nothing about. Hope you guys are doing well. Will we see you in Quartzsite this winter?

So when did OTT stop using ABS sewer pipe for PVC? Fancy! 🤣

Why just Texas? Dallas to Hohenwald 615 miles Miami to Hohenwald 960 miles Boston to Hohenwald 1180 miles Phoenix to Hohenwald 1590 miles Seattle to Hohenwald 2410 miles Personally, I believe OTT should have just left things alone and continued to retail their own trailers from their special factory location! 😂 Glad our hull is well beyond warranty years. I generally buy used and prefer to pay when we need work or do it myself. Warranty claims are a true pain as has been witnessed in many Oliver Forum threads. I talked to a Sales Manager here at Blue Compass RV, “now in 34 states.” This company bought out three locations of Affinity RV in our Prescott and surrounding valley areas that had been here for decades. He said, "You can't make money selling Olivers!" Not worth carrying the inventory for such a niche trailer when for every Oliver we can sell 10 Alliance, Forest River, Grand Design... and Winnebagos. Lots of Toy-haulers sold in the SW too! But he was trying to get me to trade in my Oliver on a fifth wheel, while I was dumping tanks at their location (a 35-ft 3 axle beast, no way)! There are likely more RV dealers in Phoenix and Mesa, across the desert valley down to Yuma AZ than any other market in the country. OTT has not been able to get one AZ-based dealer to carry their product.

In addition to Galway Girl's important questions: How are you measuring charge rate and charge level? Are you using the Lithionics app, the Victron Connect app, the SeeLevel gauge next to the pantry or a multimeter? Also, are you charging using the solar panels? This additional info will help us help you. Rivernerd

The breakaway switch connects the blue wires and the pink wire through a 20amp resetting breaker (under the street side rear bench cover). This means it's most likely on the 7 pin connector either on the trailer or on the truck side. CS

I am curious. Is there a fuse to be checked in the 2019 Elite II models for power going to the electric brakes? And possibly where?

I have a Mobile RV service coming 8-7-2025. They use a 'Wire Trace Box' they plug into the RV Plug Wiring on the Oliver. Thanks Steph and Dud B for the color plug wiring diagram. I made a copy to put with our Oliver 'suitcase' of manuals. Nothing in the manuals cover trouble shooting, that I am aware of. I will ask the service worker if this issue left the Oliver Factory like this, or something that happened afterwards. I understand mechanical fixes rebuilding auto engines and replacing parts... but not electrical. Will know... I hope then. This should not happen to any owner.

Thanks @mossemi. I did confirm that they are the solar wires. I did not know that the connector was a automatic resetting breaker. @Galway Girl. I was told by OTT that the red wire with the 1 amp fuse goes to my composting toilet fan. I believe that the propane/leak detector wire (which is likely in the corrugated wire guard) is connected to the red device with the two buttoms. I will be verifying this later today. Thanks

Have you tried contracting Lithionix?

What's your hull number. How are you charging them? Are you charging from shore power using the on board inverter/charger? If you're running from a 15 amp circuit plugged into the trailer you may need to change the settings on the charging part of the inverter charger. A little more info will help us troubleshoot. Craig

Noticed our Lithionix batteries are not charging very quickly. We have been taking the batteries out during the winter months then re-installing them in the Spring. Any ideas as to how best to trouble shoot what’s going on?

I've seen LED trailer lights work correctly getting their ground through just the hitch coupling alone but then the trailer brakes work intermittently or not at all. Happened to me a few years back with my boat trailer. Still think a missing ground is at the bottom of the list in this situation though... If it were mine, I'd hit both connectors with some DeoxIT before I even broke out the multimeter.

That makes sense, it needs to complete the circuit. However if the ground connection from the truck was faulty, I'd expect @BoondockingAirstream to have other problems, like intermittent running lights, too. With him reporting the breakaway system working properly it seems most of the trailer brake wiring is intact.

I tend to agree, and venture to say likely a bad ‘blue’ wire connection either at the male 7-pin connector or downstream on the Oliver. The OP has no issue with other trailers being pulled by his F350 and thus, don’t think the vintage of the TV or inherent factory installed equipment issues are of concern.

Funny you post that. Last summer my AC was dripping down the front street side corner. Oliver blamed that on the angle of the trailer. Something is fishy.

That sure sounds like the problem.

The nose was down. I raised the nose and the leaking stopped. I find it concerning that the angle of the trailer, ever so slight, could cause this.

I think that is a picture of an automatic resetting breaker in the B+ path from the solar charge controller. Both the red/black and the solid black should run up the the wall to the Solar CC. The red/black wire eventually goes to the battery positive/B+ and the black wire ends up at the battery negative/B-. They are zip cord wires just like a lamp cord, so you can verify my thoughts by determining if the insulation is in fact joined together as it heads up the wall under the SS bed. I’m pretty sure they will be 8AWG wire. Mossey

That trailer ground works for the breakaway switch since the battery in the trailer powers it, but to complete the brake circuit from the truck you must have a good ground from the truck to the trailer too

The brakes are grounded to the trailer frame, not through the truck connector. This is so they will still work via the breakaway switch without the truck. That makes the blue wire from the truck the likely suspect, since the breakaway does still activate the brakes. My money is still on the connector itself.

Here is some info that may be helpful -

I don't have the Truma, but on mine, the condensate line at the AC was not hooked up at the factory. I'd pull off your interior cover and see if yours has come loose, or was overlooked at the factory. Easy fix if that is all it is. Good luck. Dave

Based on my recent Truma dissection and research, I am suspicious that your condensate lines are at fault. The Truma has a pan under the evaporator to collect condensate. The pan has a drain and overflow on street and curbside. It is designed so that if the condensate lines become occluded, the condensate will pass through the overflow and onto the outside of the trailer. If both the condensate drain lines and the overflow are occluded, I understand that the condensate can drain into the trailer. Furthermore about a foot from the evaporator pan, there is a connection where the condensate line from the pan connects to the condensate line in the trailer. Again, based on my understanding, if this connection fails, water can then drain from the unit into the trailer. I hope this is clear and helps. it isn’t too difficult to investigate these issues further but it does involve an hour on the roof of the trailer, a T25 and T30 driver and some sealant to reseal the shroud cover screws after reinstallation.

Drop the nose a little. Is it dead level now?
