I've been getting slow starts so, I replaced the battery since it was 3 years old. Still getting slow starts. After searching this BB and analyzing the recommendations, I've cleaned both ends of the battery cables. It's 0 degrees F outside. When not warmed up, engine off the EDU shows 11.4 volts, during cranking the voltage is around 9.5, after starting voltage is around 13.5 but not higher. After warming up the voltage drops to 12.7. The car has roughly 150,000 miles and probably with the original generator/VR. My main reason for giving this charging system any attention was because the cold start began to be slower than usual. The battery is 1 year old, the terminal connections have been cleaned and it starts up fine.
My question: does it sound like the VR should be replaced or could the lower voltage after warming be caused by another reason?
