You learned a lot of things at the schools that were not on the normal classroom agenda. Things you learned over a few beers after class. ;=) Someplace around here, I have an old spiral notebook with a lot of notes in it. I did find my gas gage decade test box. A selector switch with a set of different resistors to be hooked to the gage to test the dash unit. The tank unit is just a variable resistor. the same as any other tank unit. The wire just needs to be replaced with a wire of equal resistance as the orginal wire. The float is just attached to a shunt that runs up and down on the wire, similar to the wiper on a potentiometer. -- Russ Wolfe '66 FB MT '71 FB AT '65 Bug (not running) russw@classicvw.org http://www.classicvw.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
