Removing the DF wire disables the generator, so this sounds normal. With the DF wire disconnected, short the DF terminal on the generator to ground. The voltage on the D+ terminal should go above 12V when you do this and run the RPMs up a bit. If this works, the generator is okay, so the VR must be bad. If this doesn't make the voltage go up, then there's a problem in the generator itself. In that case, check the brushes. If their back ends are below the ends of the holder then they are too short and need to be replaced. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
