What you are failing to grasp here is that a load test was done, even though all of the engineers said it was useless. Your statement above is exactly why I said a load test was needed; it is definitive proof of where the problem lies. If you go back and read what I've said on that thread, I didn't claim to know exactly where the problem was, only that a load test was essential in finding it.
They claims, as well as yours, to the contrary are proven wrong by the fact that a load test was in fact done. The claim that 629A (or whatever amperage was claimed) was found means nothing until a manufacturers CCA rating for the battery is posted, and I haven't seen anyone post that as a "fact" yet.
The fact that the wiring is determined to be the center of this problem means that one group of engineers is wrong, either its you internet experts, or the ones in the Chrysler engineering and design studios. As I said before, and especially in light of your outrageous claims (helium has no weight?) I'll go with the Chrysler guys as more reliable.
