Battery dying on my 2006 ford mustang gt,
My battery will not hold charge on my 2006 ford mustang gt. I have not drove it a lot, since the battery dies overnight. I have put in a new altenator and a new battery, yet it will not keep charge. The "check charging system does come on from time to time but with a new altenator? What should? Did the pulling all the fuses, didn't work, pulled the shaker 500 fuses as well, still having a the same problem.
