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.

Need All 4 to be able to provide any accurate help.
If I were to make a guess on the info you have provided, I would guess that the crank pulley is toast. It shouldn't spin.
No way you have a crank pulley that disengages under load. That is just....well...mind boggling.
Could it be you were looking at the A/C compressor clutch engaging and disengaging?
This is as weird as the Audi 6.8 volt battery story. I have to start collecting these and get to the bottom of them.
When the PS is under load, if the pulley is loose or the belt is loose, it will stop turning.
The whole thing is, I don't know how Suzuki has their crank pulley.
If it is the pressed on outerring type like on the old small blocks, then it may not make much noise until it actually came apart.
If it is a solid piece pulley only or small hub with a bolt on pulley, it may be that the key sheared, like someone said. But I would think that in order for that to happen, the bolt would have to have come loose and the hub loose on the shaft, which I would think would make quite a racket.
