ODI #11772336

Incident: September 15, 2026 · Filed: October 20, 2026

The secondary alternator (Balmar model XTMS 170 K6) overheated and failed. An RV Mechanic and a licensed professional engineer is saying luckily there was no fire. After some research, this seems to be a common issues with these Balmar alternators. The same alternator is installed on certain Winnebago RVs (Revel and Ekko) and they have issued various bulletins (23V-663) noting that the secondary Balmar alternator setup could experience severe thermal runaway. If left unaddressed, the extreme heat poses a severe fire risk. Thor has explained that because Winnebago is a larger company that Balmar has stepped up for their demands on a recall but Thor hasn't been able to get Balmar to issue a recall for the same alternator installed on Thor vans. Documentation on other reports of the same issue for your reference. - January 22, 2025 — Complaint 11637674: A 2022 Sanctuary owner reported repeated secondary alternator failures. - June 17, 2026 — Complaint 11744782: Another 2022 Sanctuary owner alleged improper grounding of the Thor-installed secondary alternator, repeated failures, and fire risk. - February 4, 2025: A 2024 Sanctuary owner reported two secondary alternator failures within nine months. The second failure allegedly shredded a belt and disabled engine cooling.
