Resolution • Information received from GM’s Upfitter Integration Department regarding removal of the Auxiliary Secondary Alternator states that the truck’s electrical system will not sense that the Secondary Alternator has been removed. • The charging cables remaining from the Secondary Alternator are live with system voltage and must be appropriately insulated & secured to prevent any shorts or electrical faults. • If you have specific questions or concerns about converting your Chevrolet/GMC truck to a single alternator, please contact your nearest GM service center.
