FAQ 79

Question: I recently inherited a 1971 beetle, and the G light comes on in the speedometer. I'm assuming this is the generator light. What is the difference between a generator and alternator? And how do you replace the generator? The car won't hold a charge, and I need to do this quickly so I don't lose my job. Thanks for the help!

Answer: Alternators are newer, and are more efficient (that's the short answer). Switching is not too hard as things go, but if you switch you want to get a complete kit with instructions. There are some people out there selling alternator conversions with no instructions.

You should be able to find a rebuilt generator or alternator at the local auto parts store. If you are replacing with the same thing, just switch the wires to the same terminals. There are a few other things to know, like how to set the fan belt tension (adding or removing shims).

Really, you need the book "How to Keep Your Volkswagen Alive". My review is online at:

If you want to consider the alternator kit, contact parts suppliers I list at:

Be sure to ask about instructions. Rocky Mtn. Motorworks has some of the best technical help.
