Load management allows the TriPac 3 to cycle the A/C compressor and charging systems ON/OFF to manage engine load only during certain conditions. The TriPac 3 and TriPac Evolution units use different load management structures. The improvements to the TriPac 3 system allow for increased alternator life, easier charging system diagnostics, and fewer system components (load shed resistors eliminated on TriPac 3).","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11019167-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11019167-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11019167","components":[],"codes":[],"topics":[],"vehicles":[{"make":"THERMO KING","model":"TRIPAC-3","year_from":null,"year_to":null,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
