I’m getting a voltage drop at my battery. I canfeel some heat of resistance where the positive cable crimps to the battery terminal. First question- is that where most battery cable resistance failures occur? If so, I am thinking of getting a splicing repair kit and make the repair there. A new cable runs about $125 and there is all the work of fishing it through the engine compartment. So second question- has anyone done a splice and if so, were you satisfied with the repair?
