I have a 97` Z71 4x4 w/350. Last Year the Alt went bad so I put a new one in and a battery to.No big deal.The problem is everytime the motor hits about 4200 rpms or so,the battery light comes on and the lights dim very low and the volt gauge drops way down until it shifts.It didn`t do this before. I have changed the alt now 3 times from different places and still the same thing happens. I have taken it to my shop and everything seems to be charging fine. I have checked all the wiring and the grounds to. What`s next?
