    By discount do you mean disconnect ? The main power runs through the Ammeter. If it is bad, nothing will work. You should pull the gauge cluster, not the dash. It is very simple. Then do an Ammeter bypass. Here is some info. It is normal for the ammeter to show a slight discharge at idle with a factory charging system. One way to increase the voltage output at idle is to go with a smaller alternator pulley. This will speed up the alternator rpm without increasing the idle speed.

    You should still read the links I sent. Applies to all of our cars.
