My new project 1996 GSX I purchased partially apart due to not running right and I have it all back together and found the source of the issue to be it is overcharging at 16+ volts. I installed a used voltage regulator and it is still overcharging and I am waiting for another one to arrive for further testing. If it is not fixed by the regulator what other sources cause a ski to overcharge, does the MPEM have anything to do with the charging system. I did unplug the red charge wire to see what voltage was on the red wire out of the regulator and it did not have any output, with it plugged back in obviously the red wire was reading over 16v. Is it normal to see no voltage out of the regulator with only the red wire unplugged and testing right at the regulator?
