Hello!
------
Standard Beetle -73, 1300, 12V generator. The generator light has for some time had a tendency to glow lightly when brake pedal id depressed and the glow alters with the turn signal light in the speedo when the turn signal is on. I have thought that this is a slight starting corrosion issue in the grounding somewhere.
Now, today when I was trying to find something to eat in the city, in the traffic lights idling and turn signal on, the G-light came on bright and the turn signal light in the speedo was completely dark whether the signal switch was on or off. I don't know if the signals worked outside or not, the new flasher relay I have is too silent. Revving the engine did not help. Depressing the brake pedal did not change anything. When I took off from the lights, the G-light went soon off. Then this happened after 10 seconds again in a left hander and G-light disappeared now in few seconds.
Then again after I had had a cup of coffee and started the Beetle, the G-light stayed on. Revving had no affect. Turn signal light was not working. After 10 or so seconds, everything was again ok. Now after this I don't see the glowing of the G-light anymore.
The generator belt is ok.
What am I looking at? Acting up regulator? Something really loose or corroded? Generator failing to charge intermittently?
