[QUOTE="Mommy Wagon, post: 7980868, member: 641740"] Big 3 (or Big 6) & Charging System The factory charging system in the 07-12 Cadillac Escalade is terrible. I have been left on many occasions in cold weather with an overnight no start condition, as have many other owners of Escalades. I have had the battery replaced under warranty, and numerous AVR tests completed - poorly designed system - that's it. Fortunately GM was good enough to provide a secondary battery location under the hood of this platform, leaving only the addition of "Police Tahoe" cables and a hold down to make the addition of a second battery easy. This is probably the route I would have taken if I was only concerned with cold day or extended parked start up. The too small 615CCA battery only become marginally better when you have 2. I opted to utilize a similar wiring layout to the "Police Tahoe" option, though I did refine it with the addition of a distribution block, a larger inline fuse, and 0 gauge wire for ALL components. What I can tell you is after properly grounding the engine, frame and body, the slight alternator whine I had with un-amped (direct to deck wired) speakers is now gone. A minor change in the initial charging system plan, the Optima batteries will remain as an option if this system fails - I went with Group 34/78 Motormaster Spiral AGM batteries - as these are made by Exide, are non-spillable, and seem to be pretty good, and are slightly better priced than Optima. What you will see is both batteries are 0 gauge to the frame and block, the areas on both block and frame were cleaned and prepped properly. The frame was also shot with adhesion promoter, primer, and a gloss black implement style paint. Every cable end/ring was heat shrunk and was covered in split loom. The only component I am awaiting is the DC Power Inc 300amp alternator, then life will be good. Maybe it's overkill, maybe not. What I can say is it has changed how I will be grounding the amps in the rear now - I will be taking both grounds through the floor to the frame. Below is the sketched layout as installed with pictures to follow............
