I was just wondering where the stock ground locations are for a 2003 Mustang V6.. I took a quick glance in the engine compartment and see three ground wires coming off the battery.. There are 2 smaller gauge wires and 1 large gauge wire.. 1 of the small gauge wires grounds right next to the battery while the other small wire and large wire run towards the bottom of the engine but without a lift or jack I cannot see where they lead.. I had issues with my battery in the past.. Issues included turning key to start vehicle and everything losing power, battery not charging, etc.. I was told that the first symptom is a classic sign of a loose cable, probably the ground.. Also was told that a bad or loose ground could prevent the battery from taking a charge.. One time while out the car was running fine and then I started to loose power where the lights inside starting turning on and off and the car died while driving.. I am hoping it is just a loose cable that is interfering with the battery charging properly.. I am not too mechanically inclined but a while back I was getting dead batteries and used a test light to see if there was any draw in the vehicle and wasnt seeing any signs of a major draw.. Again hoping its just a loose wire somewhere and wanted to find out where the grounds are supposed to be.. If i recall correctly it was mentioned that the engine block grounds to the vehicle but does the battery ground directly to the block or is it supposed to ground to vehicle?

I'm going to assume that you have checked the negative terminal on the battery itself. These are bad about splitting right at the bolt. Further, have you have ensured that the cables are clean and tight?
I'm sure that the battery itself has been double checked to be fully charged and with enough reserve capacity.
I may be able to help with a full copy of the Ford workshop manual, wiring diagrams, and PCM manuals. The wiring diagrams show the location of EVERY ground plus a ton of other information. PM if interested.
