We had reported on Sat, 3/21/26 to Winnebago that we noticed our Balmar alternator had stopped charging the battery the night before on Fri, 3/20/26 during a 2.5 hour trip to Sebastapol, CA. We drove to Santa Clara, recharged batteries with shore power and then drove to Santa Cruz, CA. This morning on Sun 3/22/26, our 2nd Balmar Alternator installed by NIRVC/Las Vegas in Mar-April 2024 under the 174 Recall caught on fire. Fortunately, we were idling in a parking lot before getting on the freeway, and could hear the whining noise, smell the burning alternator, and see the smoke coming out of the engine before the fire grew too large. We were able to extinguish the fire and keep the damage limited to the Balmar alternator. Had we gotten out onto Highway 17, ours and others lives could have been severely impacted, as we likely would not have noticed nor been able to deal with the fire as quickly. We have unplugged the 4-pin wire plug from the Balmar regulator. Once we restarted the engine, a piece of plastic came flying out, and then everything started spinning freely. We were able to drive home. We have reported the fire to Winnebago and are awaiting communication as to next steps. We have video footage of the fire and vehicle is available for inspection.
