Hello to everyone. I have 2006 KW T600 with cat c15 mxs. New issue just came in to the truck is after turn ignition off low voltage alarm rings and disconnect the power from batteries while I parked for sleep. I change the batteries and clean all cables. But still coming the same issue. Truck start with no issues. When I turn ignition on battery gauge shows 12.7 v and when started goes close to 14v . Please help.
Low voltage disconnect module is located behind driver side kick panel. Kind of hard to get to. Not horrible. Replace or bypass by bolting together the 2 wires then electrical tape over connection.
