I have replaced both the voltage regulator and the generator but the battery still does not charge.
I can charge the battery and drive it for a few days until the battery finally gives out.
Can anyone help me figure this out?

Thanks for help in advance.

Hi
does the generator light go on with the ignition and OFF when the engine is revving..

What model beetle do You Have?

did you buy the generator and voltage regulator from the same VW shop?

Should have bought an alternator... then You wouldn't need the voltage regulator...

I really need to find out what model beetle You have... it IS unusual to buy a new generator plus voltage regulator...??
the Generator usually just needs new brushes.
if the brushes were OK then it should have been charging.
The points in the voltage regulators get burnt out usually...  but NOT at the same time...

More Info please...

Lee in Australia..

Hi Lee,  It is a 1969 beetle. The light comes on when I turn the ignition and stays on while running until i turn it off. I bought the regulator first(after i had the battery checked) and it didn't help so I bought the generator. After I installed the generator it still wasn't charging. I polarized the generator yesterday but haven't been able to drive it yet since I have the front end apart as well.

You replied to another post of mine about front torsion arm parts. I found the needle bearings and the seals but I can't locate the bushings.
Thanks for the info on the grease. As soon as I get it back together I will heed your advice.

Thank you for your help on these issues, Mike

Hi Mike,

Yes, I cannot remember seeing the bushes for sale only needle rollers and the seals. I bought new seals for My 68 beetle but the originals were still OK so I left them on..
If the light stays on then the regulator isn't working correctly..
Do You have a multimeter?
You could put measure the output of the generator which is in DC same as the battery...
I'm not sure what the output should be ..
maybe 13.8-14.5 volts... with the engine revving...
You could also connect a bulb to the generator direct to see if its putting voltage out....
a headlamp bulb would be good...

was the generator New?
have you checked the brushes to see if they are new?

was the old voltage regulator the same as the new one??
wondering if the wire hookup was different..??

cheers

LEE

Lee, The generator is a rebuild, the brushes are new, the regulator had the same hook ups  as the original. As soon as I get the front end back together I will be able to drive it to see if polarizing the generator solved the problem. In the mean time I'll get a volt meter and see what I have when it is revving. I'll let you know.

Thanks for your help, Mike

Make sure the regulator is the same brand as the generator..
I read recently in a manual...  VW to VW  Bosch to Bosch...

I would think Your Generator IS charging... or producing electricity...
so, Your regulator isn't doing its job...??

maybe a crossed over wire???

cheers

LEE
