I have a 01 ranger with the 4L for 5 years now. Its been sitting in my backyard because the driver's seat had been ripped off the floor since well there is no florr to hold it anymore. I didn't have any money so i just had to left it there to rot. Now i'm working on it because i need it to work on my friend's homestead. I "redid" the floor with some galvanised steel and fabricated a support on which i welded the seat. I changed the oil and now i'm ready to start it. The battery read 0.6V so it obviously not doing anything but even if i jump start it nothing happens. I put the negative clamp on the frame to try to recharge the battery but no matter what i do the light in the cluster dont even lights up. I know i should buy another battery but i'm not sure if it will solve my problem since with the power of my other car nothing happens. I forgot to rescrew a ground under the seat so i just ducktaped it to the seat support is this why nothing happens when i try to jump start it? Please help me. I need to sell it but before that it need to start..
