Make one using a long screwdriver with the BLUNT end stuck in your ear and the other end on various parts of the engine. Try the generator first; 2 things there will make them whine, a bad bearing or simple dirt on the pole pieces which is rubbing against the rotor as it whizzes by. > However, in the process I discovered something that I am not sure > about.

On a 66, the green light is the oil light and the sensor is just a normally closed pressure switch. Oil pressure keeps it open. The light will come on if you touch that wire to ground with the key ON. - ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- Search old messages on the Web!
