I am having a problem with my battery discharging. Upon investigation, I noticed that the serpentine belt will stop turning on a hard right or left turn of the steering wheel. Initially I thought it may be the power steering pump, but also found out that the crankshaft pulley for the serpentine belt also stops as the engine continues to run. The pulley is obviously designed to stop turning if enough restriction is encountered from one of the pulleys. Has anyone encountered this problem? I could not find a way to test the pulley, as I now believe the problem can be the power steering pump or the pulley. Any help would be appreciated.
