Hi, new to forum. I have a ridgid G0449 dual battery charger, which came with a combo pack(drill/ saw/ flashlight). My problem is the left side of charger no longer charges. The red led constantly flashes, and the cooling fan runs, with no battery inserted. I have tried all batteries in port, same result, green light never comes on. The right side of charger works fine. Has anyone had this problem? I believe the product is out of warranty also. Thank you for your input.
