So, my son's 2 door Rubi has been parked (admittedly outside in damn cold weather) at school for ~3 weeks while he was home for the holidays. He got back yesterday, and this morning when he tried to start the Jeep it was stone dead. No lights coming on at all when turning on the ignition, nada.
Got him to disconnect the battery, check voltage, and it was down to ~8v. He tried jump starting from another vehicle, but even when connected up, no electrics at all. He went and got a replacement battery, fitted it, just on the off chance that the battery itself had some physical issue, and still no joy.
So right now I'm thinking it has to be some kind of fuse that's gone, if there is no voltage getting anywhere? Any suggestions on what to check first? Any help would be deeply appreciated. Next step seems to be to check whether the fuse box is getting power at all: he'll go do that once he's defrosted himself from the battery swapping work.
