The Balmar alternator installed on our RV, which provides electrical power to charge the coach battery started a noticeable whine at idle, it stopped providing a charge to the coach battery, and upon further inspection, after opening the hood, we noticed a faint burning electrical smell. To confirm that the Balmar alternator was failing, I checked its electrical output to the battery, and it was not charging. I then proceeded to unplug the regulator for the alternator to see if the whine and smell were still present. They were not. Since the whine was not present with the Balmar alternator unplugged, the burning smell had dissipated, and no charge coming from the alternator when plugged in, I determined it was starting or already failed. Knowing that there have been multiple reports from other owners that their EKKO's caught fire or had severe smoke coming from the engine compartment, that was later found to be the Balmar alternator, I made the decision to leave it unplugged. I was concerned about our safety and the real possibility of a fire if we continued with it plugged in and running. This just happened to us so we have not had it looked at by a dealer or independent service center yet, but we could make it available for inspection upon request. Please note, this is the second Balmar that has failed on us in our four year ownership of this RV, and we have a friend that has had five Balmar's fail on him! Winnebago needs to be held accountable and should be required to remove and replace the Balmar alternator from all owners RV's and replace it with a more suitable and capable alternator that will provide the secondary power they advertise when they sell this model to consumers.

What owners say
October 10, 2025. The vehicle is a 2022 Winnebago EKKO RV on a 2021 Ford Transit with 49,000 miles. The incident occurred after driving the vehicle for about 5 minutes with outside temperatures around 50 degrees Fahrenheit and noticed an unusual high pitch whine. When I opened the hood the Balmar MC-618 Alternator unit was extremely hot, smoking, and had a strong burning smell. Since the EKKO models have had numerous reports of secondary alternator/Balmar malfunctions I knew enough to disable the alternator by unplugging the 4 pin connector on the Balmar 618 regulator before traveling any further. The following morning I plugged the Balmar unit back in and the whining sound and burning smell immediately returned. There is a the federal safety agency Safety Recall 23V‑234, Campaign # 174 EKKO 12V Charging System, sent out by Winnebago for this very safety issue due to fires. This recall was completed during the time that the original owner had this 2022 Winnebago EKKO (prior to our purchasing this 2022 Winnebago EKKO in June 2024). There have been numerous failures on Balmar units that have had the campaign #174 recall completed, including ones performed at the factory. The Winnebago fix is obviously not working and is still an extreme fire issue.

Since the Ekko models have had numerous reports of secondary alternator / Balmar malfunctions I knew enough to disable the alternator by unplugging the 4 pin connector on the Balmar 618 regulator before traveling any further. The following morning I plugged the Balmar unit back in place to see if the high pitch sound reoccurred. The sound immediately returned and I used my infrared thermometer which read 438 degrees Fahrenheit on the Balmar alternator. The Lithionics battery app indicated the batteries were 90 percent full but would no longer charge, leaving me only shore power to recharge the batteries. There is a the federal safety agency Safety Recall 23V‑234, Campaign # 174 Ekko 12V Charging System, sent out by Winnebago for this very safety issue due to fires. We had this recall completed at the Forest City Iowa Winnebago factory in April of 2024. There have been numerous failures on Balmar units that have had the campaign #174 recall completed, including ones performed at the factory. The Winnebago fix is obviously not working and is still an extreme fire issue.
Winnebago recall 174 (the federal safety agency campaign 23V234000) regarding improper electrical wiring design and installation by Winnebago was recently completed on my RV. After completion of this recall I experienced another electrical fire in the engine compartment (my alternator had previously caught fire due to wiring and design defects noted in Winnebago recall 174). After extinguishing the fire I observed the Winnebago recall 174 remedy had been completed in such a way that an engine compartment wiring harness was under tension and in contact with the threads of a bolt on the backside of the new alternator installed as part of the Winnebago recall 174 remedy. This seems to have resulted in electrical anomalies and eventual ignition of the wiring harness. There were repeated brief intermittent brake and rear hatch warnings shortly before the fire (there is no rear hatch). The windshield washer system failed after uncommanded operation of the windshield wipers. Multiple other warnings and cautions flashed on the screen too fast for me to identify them. This all happened just prior to the fire which occurred during an engine start attempt while parked. I have video documentation of the smoke and photos showing fire damaged wiring and its location relative to the alternator bolt. Components are available for inspection. I have not yet contacted a dealer, service center or manufacturer yet since this event happened only days ago. My safety has been compromised by two engine compartment fires involving the same defect both before and after the Winnebago recall 174 remedy. For this to happen I have to assume either faulty mechanical completion of the recall or the recall remedy itself. This is but the latest fire hazard I have experienced with this unit (two actual fires, loose propane fitting which slowly flooded the coach with propane, overheated air conditioner that melted insulation in the ceiling and impending the federal safety agency campaign 24V541000 for solar fuse fire hazard).
The solar panels ceased to charge the batteries. I found a 40A Fuse holder behind the solar controller in the coach, that had melted and looked like it could have caught on fire.
This is allegedly related to the Balmar relay system installed by Winnebago in the Ford Transit van.It is currently at the dealer, Colonial Winnebago, in Millstone Twp., NJ. Dealer can be contacted for inspection. We began traveling at a 25 mph speed for about 2 miles when smoke began to flow from under the hood. We pulled over to inspect; 911 was called. Smoke and flames under the hood were visible and continued until the fire truck came and extinguished the fire. Our safety and the safety of others was put at risk as the unit did not display any warning signs on the dashboard, there was a fire and smoke under the hood, we were in a public parking lot, and the unit carries 2 20 lb. propane tanks. Problem was diagnosed by our local Ford dealer, who stated that this is a Winnebago issue, as this was a Winnebago specific modification to the Ford. Unit was not drivable and needed to be towed to Winnebago dealer for service. They know about this issue - and have known for some time - but have not yet released the recall. We do not know at this time when the unit can be repaired. I do not know who has inspected the vehicle other than the Ford dealer and Winnebago dealer. No other warning signs or symptoms before the incident occurred.
The auxillary alternator caught on fire. The dealer retained the part when replaced. Fire risk to ourselves and entire rig. Yes, the problem was confirmed by a dealer. The Yuma, Az fire department responded and wrote a report. There were no warning lamps, messages or other symptoms,
The secondary alternator caught on fire while traveling and damaged the Ford tensioner that supplies AC compressor power
