Ground cable from block to frame?
Doing my latest oil change, I noticed the ground cable going from the engine block to the frame is in pretty rough shape, especially at the frame contact point, and I've had voltage issues for almost a year now. Car runs usually around 14.8-15 volts no matter what is running.
A. Can I get just a replacement cable from somewhere without having to measure and cut my own, crimp on ends, etc. If not, any idea what the length/gauge is for a 2004 L36 cable?
B. Would having a bad ground cable cause the high voltage issue I'm seeing? The info center reads 14.8-15 (sometimes as high as 15.2) and readings are confirmed with my DVOM, and the dash is spot on, voltage wise. Everything seems to be working ok, but the unusually high voltage has me concerned.
