05 Granite
in Mack Truck Q & A
Posted
Hello everyone! New kid on the block. Wanted to see if I could get some help. Have a 05 Granite CV713 and every time I idle for awhile I get a lightning bolt on dash. Truck comes with automatic shut off I think after 8 minutes but don't quote me on that, sometimes I hit the button on the dash to override it but if I idle for to long (10 minutes or more) the bolt comes. Could someone tell me what's going on. Thanks
