So I put a new fuel tank in, she (1974 cj5) is running good. The fuel gauge even works. So I'm driving on my way to work tonight and a guy pulls out in front of me. I take evasive action and drive around him to prevent a collision, as I lay on the horn. The entire jeep goes dark and I roll to the roadside. I didn't have time to check under the hood, I'll look her over tomorrow. I had to drive my wife's car to work. I did disconnect the negative terminal when I was doing the gas tank, and I just twisted it on finger tight. I'll check that first but don't know where to go from there.
