However, because of voltage drop between the batteries and the cab distribution area, this is not a true representation of actual system voltage. To improve the accuracy of the Command Zone voltage gauge, a 10/2 harness will be run from the right-side battery box to Output module #1 (or Input Module #1 if Output module is not present on apparatus). This will provide a more accurate voltage input to the module responsible for populating the voltage gauge value.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-11010451-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-11010451-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11010451","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.
