2006 Chevrolet 2500hd Duramax when headlights are on I am losing ground to AC compressor , I also get low coolant indicator, driver side head light real dim, passenger side not so dim, and check engine light is on. When I run a ground wire from the front left battery and to the AC compressor the compressor works and the lights get brighter. After resetting the check engine light and turning the head lights off I do not get the check engine, AC compressor works. Where do I start???

Of the four problems three were cured when I replaced The Two Batteries. Ground loss is left.
