Im sure this has been asked before, but here it goes. My wifes Tahoe after sitting for a day or two will not start. Voltage drops to 11.9-12.1? Ive checked all the normal stuff cables, interior lights, visor light, radio. Nothing. Strange thing one of the HID quit working on the low side also. Only thing that seems to help is pulling Battery fuse under hood. New cables and battery were installed and solved issue for a couple days then sos.
