Balmar whine has indicate to be the first step before fire starting in the engine compartment
2023 Winnebago Ekko electrical complaints

We believe our Balmar (the second alternator that powers our Lithium batteries) failed and then created enough heat to either have a small fire or produce copious amounts of toxic smoke. This is a known problem with the Winnebago EKKOs. There has been one round of recalls for the Balmar re-wiring which we had done at the Winnebago Factory Center in Forest City, IA on November 21, 2023. We were in the parking lot at Whole Foods in Jackson, Wyoming when this happened. We opened the hood when we smelled the plastic burning smell and smoke was pouring out. People were gathering and telling us to call 911 to get the fire department out. We decided to discharge the fire extinguishers provided with our EKKO (a Kidde ABC model). If the whole thing caught fire, obviously other people and cars parked next to us would have been in danger. Yesterday, we heard a new “whine” coming from our engine and noticed that our app that measures the power coming into the lithium batteries was fluctuating way more than usual and so we suspected the system was starting to fail. We had no idea it would fail so quickly and so dangerously.
After completion of the federal safety agency Campaign Number 23V‑234, the Balmar alternator charging system on my EKKO has twice shutdown and gone into a locked state which also trips the 250A house breaker in the RV. This state disables all charging while the engine is running and also disables the house 12V system due to the breaker trip. The locked state is supposedly triggered by an alternator over temperature condition. The NHSTA campaign previously replaced this entire Balmar charging system and its wiring, however, there are still clearly issues with the post-recall system as it fails and shuts down. The safety issue here is that the Balmar system over temperature condition can lead to a fire. Winnebago has not been helpful and refers me to Balmar. Balmar is entirely non-responsive and does not answer any calls or emails via their support mechanisms.
The Winnebago installed under hood generator (Balmar brand) produced a burnt, smokey smell immediately upon starting the engine on September 22nd. The previously 3 days when the vehicle was started and driven a whining type notice was coming from the generator. This was the first time any noise from the Balmar generator was given... 18,000 miles had been put on the vehicle during the last 11 months without issues. Since this is a well known issue with the Winnebago Ekkos I knew to pull the 4 pin connection to the house battery system to prevent any fires or other issues. With the Balmar being disconnected from the battery system there is no noise or burnt smell coming from the Balmar generator. And vehicle could be driven. As mentioned, Winnebago is well aware of this issue and said they had fixed the problem when I purchased this camper RV in 2023. No one has looked at the vehicle yet but I will have Winnebago or the dealer look at it when I can get it scheduled.
Have completed work for: the federal safety agency SAFETY RECALL 23V‑234, had failure AFTER recall. Vehicle has 16250 miles on it. Balmer alternator failed, heavy smoke, very bad smell, no fire visible. disconnected 4pin control wire Reported to Balmer and Winnebago.
Last August 2023 we had Recall 174 completed at Winnebago’s factory service center. This was for the Balmar 2nd alternator, Regulator, and wiring harness. This morning around 6:45am upon starting the vehicle I smelled smoke. Since this is common when the alternator fails I checked our lithionics battery app to discovery we were not inputting any amperage to our house batteries from the 2nd alternator. It had burned up and failed once again (had failed last year, recall was done to fix it, and has worked since August 2023). We are not the first owners who have had the recall done and have the system fail again.
The Balmar alternator gets very hot and emits very loud high-pitched whine. Others who have reported this heat/sound without further action have reported the alternator has caught on fire.
The balmar regulator/ 2nd alternator is failing and presenting a fire hazard based off of Winnebago’s own reports and other owners who have experienced fires to their Ekkos. Because of this we have had to spend a considerable amount of money getting another safe charger option (dc - dc charger wired properly and safely unlike winnebagos 2nd alternator/balmar regulator) from the primary alternator installed since we cannot rely on or use the 2nd alternator with the balmar regulator without threat of fire, serious injury, or possible death. We have not been advised on what to do to prevent this and Winnebago is not providing an actual remedy in a timely fashion (or financially reasonable to us as a owner, as we have to pay out of pocket to travel 3000 miles round trip for this repair when it is available). They need to provide guidance immediately as this is a life threatening hazard and remedy it as soon as possible, while not putting the owners lives at risk and providing compensation for owner traveling thousands of miles for the fix.
