Classic/Antique Car Repair: 1971 vw super beetle conv., speedometer, conv

Question
Hello, I have a little 71 vw bug...There is a little red light
in the speedometer area on the left that has a "G" this comes on at lower speeds... do not know what  it is opposite the "Oil" guage. Thank you, I can no longer find the manuel. New engine installed about 4 years ago.and this is the first this has appeared on.

Answer
Hi Jean:
"G" Stand for Generator. At very low idle speed, the generator
belt is not turning fast enough to charge your battery. If it stays
on will sitting in traffic, your belt may be slippng or the generator
could be going bad. Check the tightness of the belt first. It just may
need a quick adjustment or replaced.
