Having trouble with alt 2 light in my blazer. it is flashing most of the time.dont seem to b any trouble charging the numbers r all good i been running it a wile like that.and have had a similar problem with my truck replaced alt and light stoped so had this one rebuilt by a rep shop and it still flashes. I have noticed one thing that seems off is that the brown exciter wire is 24v with the key on but if the vehicle is running and its connected to the alt the voltage jumps back and forth from like 14/15v to 28/29v if the light is flashing and stays 28/29v when it is first started untill the light starts to flash thanks for any help in advance
