I could do this without hurting anything other than the sealing paint on the screw that holds the cover on. I MIGHT even be able to fix it. Seems odd that a wire loop would be useful here. The function of the diode (Bosch called it the Variode) was to be non-linear. The length of copper wire would be pretty linear. Now that you mention it, I just took another look at this one and the shunt that is there on all the 12V diodes is not here on this one. I'd love to look inside, but I'd have to break the seal. I think I'll go downstairs, however, and refresh my memory on where that shunt actually was. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
