Interesting. I'm guessing there was a mid model year change or similar as my 66 has the 9 pin relay mounted to the drivers side fender and not directly behind the speedo as shown here?
Sooo... what about those of us running internally regulated alternators? I wish I could just run the power under the rear seat like a late model bug but the wires are bundled together in the harness. What’s the best way to route power without a regulator mounted to the generator???
This depends on the year of the car. If you're working on a 6 volt car, just run a power wire from the "+" alternator post to the starter "+" post. Essentially, just like we did at the 2:50 mark.
@@doginu - not true. 6 volt cars have the main wiring harness in the roof, not through the quarter panel and under the rear seat. 1966 and earlier 6 volt cars have the regulator on top of the generator. So for those converting a 6 volt car to 12 volts, with a generator instead of an internally regulated alternator, this is the way to go. Ideally, if you're converting a 6 volt car to 12 volts, use an internally regulated alternator so there is no need to wire up a regulator.
Hi, I'm from Buenos Aires and I have a VW'66 with a 12V Dynamo. I don't know what regulator to put on. Could you help me? Thanks ... excellent video ...!
Not as of yet, no. My best advice is pull the windshield and the top of the dash. This allows access to the back of the dash without contorting yourself underneath the dash through the door opening.
@@Sam_Mebane thanks for responding Sam I'm doing a complete wiring harness so the dash is out, it's mostly done and I'm looking for a good tutorial( I'm not the wiring guy) there's plenty on the bug not the bus. Previous owner thought he was an electrician thank you I'll get her done
This wasn't our car and was filmed quite some time ago. If memory serves though it was an EMPI 30PICT - www.jbugs.com/product/98-1288-B.html - and at the 2:40 mark you can see that the vacuum line on the carburetor is capped off.
I didn't see the spade connection to the starter. Was that also in the engine wiring harness. I know that comes from the front of the car but I didn't see you run that wire. Or is that just not visible because it is behind the fan shroud and tar board?
The wiring was installed as part of a series.The wire was run through the firewall to the starter in this video - ruclips.net/video/an0KPO4jR7o/видео.html
There is no black wire that comes from the starter. B+ indicates battery positive power. The wire from the right side of the engine compartment came from the positive battery cable post on the starter.
@@Sam_Mebane hi I have a 66 vw with 6. Volt system it will not start nothing when I turn the key. New battery&starter should I just go through all electrical? Could it be anything mechanical? Where can I get a 6 volt manual showing all mechanics (how to) or help when I need it
@@robinlowe3976 I would start by checking for a good ground connections at the battery cable and at the transmission ground straps. People often overlook them assuming that as long as they have "power" (positive) that everything is good. Rust, paint, loose connections, old cable, etc. can all lead to a bad ground connection. 6 volt systems use less voltage but more current (amps) than 12 volt systems so the grounds are especially important. As for a manual, the factory service manual ( www.jbugs.com/product/11-0701.html )for your car is a great option but often times too technical. For the beginner and even seasoned VW fan, the John Muir "Idiot Book" ( www.jbugs.com/product/11-0990.html )is a great manual that uses common terms and is easy to follow.
Where did you get that battery? I need to replace the battery in my '68 Beetle and the car supposedly needs a group size 42 battery. Only "problem" is that the 42's terminals are backwards from the battery you're using, which appears to be the correct layout for a Bug. A size 42 battery WILL work (that's what I took out of my Beetle after all), but I'm curious where your battery came from.
The battery we used for testing is a Full River FT825-34 High Capacity Dual Purpose AGM Battery. It is our bench testing battery and stays in our shop and not a battery we would normally run in a VW. We normally run an Interstate MT-42 battery and either flip the battery around so the posts are at the front or just move the ground cable mount at the chassis.
is there any difference from wiring up a 64 as to the 66 if the 12V conversion has been completed?
Yes, the biggest differences being the turn signal switch (with dimmer) and the hazard switch. Otherwise the cars are very similar.
This helped me with my 1972 beetle
Interesting. I'm guessing there was a mid model year change or similar as my 66 has the 9 pin relay mounted to the drivers side fender and not directly behind the speedo as shown here?
That is an oddity. I've never seen the relays mounted anywhere but behind the speedometer in all the Beetles I've ever worked on.
@@Sam_Mebane I'd add a picture but don't know how.
@@starlightsims9229 it is where it is, as long as it works, it doesn't matter where it is!

Did you solved the “problem”? I’ve the same question… but I’m really new in this things, basically I’m trying to understand it and do it by myself…

You don't attach the regulator under the generator strap like they did here. Best way is under the rear seat on the driver side.

@@Sam_Mebane Look at 2:50, you do not attach the regulator like that. It will vibrate and wear on the front dust cover. Mount it correctly
Hi, I'm from Buenos Aires and I have a VW'66 with a 12V Dynamo. I don't know what regulator to put on. Could you help me? Thanks ... excellent video ...!
The standard 12 volt regulator for a generator should do the trick. www.jbugs.com/product/30019.html
Have you got a video on wiring a 68 bus dashboard? I'd sure like to see it I'm having trouble
Not as of yet, no. My best advice is pull the windshield and the top of the dash. This allows access to the back of the dash without contorting yourself underneath the dash through the door opening.

What carburetor is being used? I cant find one without the vacuum lines.

@@Sam_Mebane thank you
About the red wire that was trimmed and connected to b+ besides the black wire that comes from the starter, where does the red wire comes from?
There is no black wire that comes from the starter. B+ indicates battery positive power. The wire from the right side of the engine compartment came from the positive battery cable post on the starter.
What crimping tool are you using for the non insulated connectors?
A non insulated wire crimping tool (Google search that and it should bring them up).
Could someone make me a diagram as to how I could wire up my voltage regulator on a dune buggy to charge ???
We kind of already did - www.jbugs.com/store/graphics/00000001/23/300019-VW-12-Volt-Voltage-Regulator-Wiring-Diagram_540x540.gif
I have no fuse box
I have no idiot light or speedometer
@@JamesBrown-126 then wire it up to your battery and switch.
@@Sam_Mebane where on the switch ?
Battery, or accessories ?
Is this the same wiring harness for a 1962?
Yes, this Complete Wiring Harness (www.jbugs.com/product/WK-113-62-64.html) fits 1962 through 1964 Beetles.
Love your vids guys!!! Great job!!

@@JBugsVWParts Thanks for the feedback! Was thinking an MT-42 as well...they seem to get the job done and the cables will fit.
