[QUOTE="jrwalte, post: 4421502, member: 584454"] You can't test the location for matching voltage of the battery unless you also connect the ground wire. With the ground wire attached to the chassis and the battery, place the DMM on the battery positive and ground chassis. You should get the same voltage reading as when you touch the battery negative. .1 volts when testing the way you are testing is a good sign that the location will be a good ground. As for the block to chassis ground, I just used the existing ground location and replaced it with my 0 guage. Was that screw hole in your picture already open or did you remove the screw? Do not place a new screw into an old location that had no screw. I do believe that some are intentially left open by the engineers. [/QUOTE]
