This is typically caused by interference from light dimmer switches in the RV. Brinkley will pay to inspect, and if necessary install a Ground Loop Isolator in-line in the audio equipment to eliminate the interference.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11025142-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11025142-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11025142","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"BRINKLEY RV","model":"MODEL G","year_from":2023,"year_to":2026,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
