Also included color arrows, the red is the original hole that the tap broke in, The yellow area was spot were there was already a small hole and just drilled it tad bit wider to then use a 1/4 tap and was able to create small bit of threads to then connect the two original wires, the tiny one marked by the green arrow, and the large one with the blue arrow. I also added the grounding kit wire which is pointed to with the purple arrow. Also, as I mentioned cleaned it to bare metal before putting this bolt in. Also, this little hole was already there and basically just threaded it so don't believe I penetrated the housing. Also, like i metioned prior to all this the vehicle started just fine, and all I did was undo these cable to then add this new grounding kit wire which has then lead to vehicle not starting. Also, I just looked under the car and that large grounding cable that is pointed to with the blue arrow go to the frame. I just don't understand how it started just fine prior to this and now it won't start. All I did was install the battery cutoff switch and the Kascar 535-A1 Ground Kit, 4 Wire, A, B, C, D. Is there something else from this install that could be effecting it from starting? I just assumed it was this bolt that broke that was causing it not to start, also is there way can check and make sure the housing is correctly grounding from this new spot I am using? Just really dont know what is causing the problem and appreciate any help you can provide.
Thank You
