Red light while revving low (sorry, no creative title this time)

Just in case the guy from the generator rebuild calls it quits at the last minute, does anyone know of a service where I can mail the generator in for a rebuild? I have searched high and low and no place offers a rebuild service, only exchanges for screw terminal generators. I have also searched how to replace the brushes and polarize the generator, and they seem like pretty complex tasks for my experience level, and it would be a shame for me to damage a rare generator.

Ashman, KTPhil beat me to it, but the push-on generators were not exclusive to only the 1967 model year. Some were used also on the '68's, as well as a 6v version used in some '66 applications. The numbers dating the generator you pictured in your post = Dec. 1967 = would mean it was from the 1968 model year production (August 1967 -July 1968)

Here’s what I wrote in a discussion on generator covers in this thread the other day

My ‘68 Euro spec came fitted with what is often erroneously called the “67 year only” generator with push on generator terminals. It has been in the family since new and does not have the covers fitted.

Much has been expended on that subject: For 1967 The Beetle Generator part number is/was 211 903 031 (from VW Parts Book) applicable from Engine Number H 0 204 001 (August 1966) to/through July 1967 Model Year 1967 for Special Options Code 610 (12 Volts) USA/Canada and wherever else 12 Volts may have been used. Beginning in August 1967 for Model Year 1968 the Generator Part Number was 211 903 031 A-a change in the Generator was made!

Prior to 1967 Workshop Bulletin E - 72 August 1965 states that All generators and Regulators are now of the Push-on Type from 2 August 1965 (October 1965 for Type 2). Workshop Bulletin E of 27 March 1968 states that the D+ and DF terminals of Generator and Regulator have been changed from Push-on to Screw type. Additionally that bulletin states that if Generators or Regulators of the Push-on Type are used to Replace the screw on type-additional connecting parts are necessary and lists the needed parts! So, one way the Push-on type could be used outside its birth Year or Engine number sequence!

Thanks all for the correction.

It sounds like VW went from screw on terminals for 6v generators to push on in the '66 model year. In '67, this feature carried on into the first generation of 12v generators. It was changed back to screw on for the '68 model year, but as is typical for VW... they used up their existing stock of push on terminal 12v generators for the early '68 model Beetles before switching back to screw on terminals.

At least that is what I get from the above details. Strange that VW would change and then change back?

My guess is that VW found the push-on terminals loosened from vibration over time, and decided the post and nut approach was more reliable.

Update:

I finally received a solid state regulator from jbugs and installed it. The rattle is gone already! I didn’t care at all that the regulator isn’t period correct, since this bug is more of a driver than a garage queen. Maybe I’ll install a period correct one when I eventually sell it, but that might be happening way in the future. The red light still comes on during some stops, however I hope that it will get fixed when the new generator gets installed. Thanks for the suggestions on getting a ss vr! And thanks for all the good advice and trivia on the 67 bug generator system!! I’ll still be giving an update when the generator gets installed though
