The large draw of electrical current from the mechanical siren activation, would starve other electronics in the cab. Sometime causing HVAC systems, radios and other electronics to shut down. Rerouting the main battery cable to either battery box, provides an independent voltage source for the siren, causing less electrical impact to cab area components.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-11010452-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-11010452-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11010452","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"PIERCE","model":"CUSTOM CHASSIS","year_from":2000,"year_to":2006,"match":null,"vehicle_ids":[]},{"make":"PIERCE","model":"CUSTOM CONTENDER","year_from":2000,"year_to":2011,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
