We have a 2012 Western star tri axle dump truck. Driver did pre check this morning everything was fine, got to the paving plant lost backup lights and now alarm comes on when you apply brakes and the running lights all blink and alarm sounds when they are on. Disconnected wire to alarm and no lights work, anyone ever encountered this?
2012 Western Star electrical Help!
