So I installed the new generator
Wired everything back up Exactly the way it was when I bought it only thing I didn't plug in was the. Reverse light, I'm missing the fuse currently and figure there's no point.
The light indicating the generator is not charging properly. Still on?
No voltage from generator D+ df. D+ and bodyground( 7v )
Pull the negative terminal off the battery car dies
It's the same as the last one. Guy told me it was definitely good, and I needed to do nothing to it. Just put it in.
I painted it i was very careful airport tape over the large holes that look into the wires and put it in, that's it.
He even removed the screw for the d- after I told him what I did.
So what am I doing wrong?
Even if polarizing or depolarizing was the answer I can't because the screw is gone.
Generator wiring
Coil wiring
Regulator wiring
The little triangles at the bottom are what come on when the car is running?

| Under "MPH" is the left/right turn signal indicator. It should blink when you use the signal switch. |

I don't know how it's supposed to be wired up front.
They're probably reversed.
Everything is spray painted purple.
That's how it worked. Previously, the lights went off when the engine was running.
And there's only one light bulb poast
When I turn my turn, signals on a tiny red light flashes off to the left.
Same with emergencies I need to have the turn signal on for the emergencies to flash
All of that's pretty jacked up up front.
Either way. I'm not getting voltage from the generator
When I pull the negative terminal, the car dies. I have ran cars without a battery before they were newer. I know it's not a good idea, but it was an emergency.
I would imagine this car should run without a battery. If the generator is working?
Just a simple test to check the generator right?
I would imagine. Even if the wires are wrong up front indicating the wrong thing, the generator should still power the engine.?
I don't know. I can take some pictures of the wiring up front if you think it'll make a difference.
Not sure you could make heads or tails of it. I did figure out which wires far for the headlights and turn signals. Once they go up to the relays, though
I feel so dumb. I had like, literally everything working accept the reverse lights
I accidentally fried my previous generator,
and now those lights, whether they're turn signals or not, stay on previously, they went off when I turned the car over. |

This is the back of my speedometer.
I do believe it's the bottom center.
There's only one spade bit
So I don't know how it would know which side I was using.
I do believe the one with some green showing is currently connected to my turn signals |

Hang in there. I've had VWs in my life for almost 30 years and I fried my 6v generator just yesterday.
Even the simple electric systems on these bugs can get very confusing. And having it painted purple is a bonus challenge.
Have you found anything that cleans that damn purple paint off of the wires? I'd start with cleaning the ends of each so you can ID them. Is it factory wiring, or an aftermarket harness?
I'll read up on more of your posts to get a better idea, but you'll get better specific guidance from other 67 owners.
With electric, I'd suggest you print the wiring diagram, or have it open and handy on a tablet, and just follow each wire, making sure they start and end where they should. And clean as you go. |

Change the regulator the light went out, except when I step on the gas. It's very bright. i'm getting voltage from the generator now.
Battery doesn't go up but
Did I wire it wrong?There were no instructions
The other generator was probably good. It was the regulator all along

Thank you so much.
I haven't found anything that cleans the wires. Try to acetone a little bit.
i think it'll just be time and patience
Probably easier if I took all the wires off and then scrub them, but i'm afraid I'll mix them up the ones that go to the relays, they're pretty confusing. I'm not sure they're even plugged in correctly.
Although I am pretty sure it's original wire harness with minor modifications.
Yeah, somebody was saying that I should string them all together, but I don't really know how.
Probably more intuitive from a computer my phone doesn't show the website very well
Navigation's a little tricky.
Especially when I'm doing it from my email. |

Also do keep in mind that the generator needs a good ground to the outer body to work well. Paint is not so great as a conductor for the most part.

Do you mean the body of the generator need not to be painted.?
I don't know where else I would put a ground from.
I did fix the issue of it. Not charging the battery. It was the regulator the whole time.
The other generator was probably even good
It's just weird i wasn't getting voltage. When checking the d + df the same you way check a battery plugged into the regulator not plugged into the. Regulator
Got the new regulator and now I am getting. 9 at idle.
Either way, it's charging the battery now.
Battery back up to 12.7 , not running
after being like 12.4 and dropping with the bad regulator
I'm almost there just need to figure out why that light gets brighter. When I rev the engine didn't do that before?
Is that light really supposed to be a turn signal??
Anyone feel like posting a picture of how theirs is wired.?
I would need to see where the wires are coming from that way. I could try to follow it back because I don't have color.
I've heard of people connecting it to a buzzer. That way, if your fan goes out while you're driving, you'll notice right away i might do that once I fix the major issues |

Generator should be zinc plated which makes for a good ground to the gen stand. So as long as the generator body is not rusting.... There is a 6mm threaded hole forward of the gen strap. You can use that hole with a machine screw or bolt to run a brown ground wire to the body. Strip away some of the paint just around the hole for better grounding.
1968 and later beetles VW ran a dedicated brown ground wire in the wiring loom from the generator to the regulator under the rear seat.

Hope you can see these
This would be easier the previous regulator didn't have the brown tab
But this is what I think you mean
Unfortunately this way is not currently possible.
i can't get to my wire harness through the car.
I think i need to drop the engine to get at that
I am a little apprehensive about doing anything with the D- that's what started this whole thing
Your sure it won't fry my generator???
Can I repair the old regulator?
I probably make it to the shop now
I will just unplug the light ?
It gets so bright with just a tiny amount of gas probably blow the light
It's just so weird it stays off at idle I wired it like it was before?? |

Should be ground wires from each taillight to the body. Left panel should remove easy enough if you want to run it there.

Small light on the left I'd the generator light. Small light on the right is oil light. The double arrow in the middle is turn signals. Sounds like someone crossed the wires at the bulbs. |

Ahh, your gen is working now!
But I guess, your 3 lower speedo control bulbs in pic are wired wrong.
Originally they are NOT grounded, they are hanging on one terminal 15 +.(the deepest post in the middle of speedo, normally a black wire, coming from fuse box, ignition switch)
See wiring diagramm here on samba! https://www.thesamba.com/vw/archives/info/wiring/bug67.jpg
Make sure, all your electric components and bulbs are 12 Volt and not 6 Volt. Both was possible for model 1967, at least in some countries, the beetles were delivered. |

So I switched the turn signal and gen light
Wasn't hard the bulbs just came out and just popped right in to their right spots
Tried running a wire from D- to ground no change
Tested the whole for D- and body good continuity, so it's probably grounded?
Probably tests tomorrow D- to regulator with external wire to bad i don't have a rear pop out window lol
But is their any point
Ran some tests on the regulator
Battery. 12.6 / 12.7
Going to bat. 12.6 / 12.7
Coming in from Df. 11 / 14 ~
Going to light same as Coming in from Df
I might try the old regulator
Maybe generators just need time ?? To energize?
(i don't know i am taking shots in the dark)
I probably have it wired wrong
It should be nothing to the light right ?
I have it wired like the picture I drew except the brown |

Might try polarizing the generator.
From your diagram it looks like the gen/reg wiring is correct.

Lol, did you read how I broke the last one
I don't think my husband will let me
It does keep the battery at around 12.7 with the car off
i don't have the tachometer installed yet maybe it's a shift light (i am kidding)
I maybe try polarizing if nothing else works
I might take in to where I bought the generator
I would need to take it on the freeway to get their or up a really steep hill
I'm not grate at driveing it hard to find 1st after 3rd 2nd is hit or miss too
I want to check the linkage or grease something haven't really looked in to it yet maybe the trans flush did the trick?
I hate having lower cars towed
They always scrape them
My exhaust needs some love already so maybe just do it anyway
I think I will block of the heater boxes just to up the air flow
I do think I have most of my engine tin just missing for the preheater and the one over the transmission from what I can rember after comparing to the diagrams you all have shown me
If I were to just unplug the light at the regulator so I could get it to ?? What are the chances that it will blow the generator or regulator in its current state
I am sure the light will blow if I go over 5 miles and hour maybe less
it does seem to be restricting voltage to battery and starter
I have to have it wired wrong
I will post some pictures of it tomorrow after work
Thanks for your advice |

Do you mean block off the heat to the interior of the VW, or block off the cooling air to the heat exchangers???
