Hi, After having my car battery tested,I was informed that I have a high output voltage reading.What can I do to fix this?The car stalls while driving.Its like the car just looses all power and cuts off. At first I thought I may have a fuel system problem. But it looks like I have a drain on my battery.Keep in mind this is a brand new battery(less than a week old.)Also could it be the crank sensor.

Your charging system issues may not be related at all to the car cutting off. That very well could be a bad Crank sensor causing that and in fact those cars are pretty notorious for that.
