Want to install a stock 66 type1 speedometer into a manx style buggy. I dont need to run anything other than generator light. Other than that do I need to any other power wire or just the ground wire and cable?

Thanks for the PICTURE, that really helps. Does that mean my sender is bad or maybe not making a ground to the block? I also went to a VDO Electrical Oil Pressure Gauge and 2 pole sender. But could not get it to read. Every time I put power to it, it would lay all the way over to the other side. I tried every thing. So I just took it all out and put the stock sender in, till I can buy a mechanical gauge. Maybe it was not making a ground to the block either. I thought about putting a eye end wire over the base of the sender, screw the sender back in and run that wire to a solid ground. Do you think that would work, cause maybe it is the paint on the block that is keeping it from grounding? I have spent so many hours racking my brain on this wiring, that I am just about ready to give up and sell the car. I love VW"s but this one is putting gray hairs on my haed.

It is a +12 volt source. Those three lamps are grounded through the oil pressure switch, the voltage regulator and turn signal relay respectively. When you turn your key on, the generator lamp and oil pressure lamp should turn on and then go off when the engine starts.

Hey VW guys, I need help. I have a 73 Beetle. When I turn the key on, there is no oil light. When I walk back to the sender and unplug it, the light comes on. Also, at the base of the oil/ts/gen. light bulbs there is a bi-metal strip that connects all three with a male plug in the center. Is that a power source or a ground connector?

Thanks Andy. I'll try again later. I figured that was part of the problem and tried and tried to get it mounted without any contact, but just never could get it. I see the difference in the face plate you mentioned. Just happy to not have one with the red reserve area! Now I just need to get it working right.

Man I need one of those 68 gauges for my 61 Vert. Anybody got one reasonable in good working condition? I can trade a good 1969 unit for it.

Time to bring this thread back out.
I'm having issues getting the electronic fuel gauge to work correctly in my 62. I have a 68 speedo and brand new sender, vibrator, and gauge ( I swapped the
face plate of the new gauge to the older style).

Here is the problem. Everything works perfect when OUT of the speedometer. Here are three pics taken with the gauge and sender
just setting out and using jumper wires.

Sender in the empty position

Sender around the halfway position

Sender in the full position

However, when I hook it all up in the speedo, I get this.

It goes straight to full, but there is less than a gallon of gas in the tank. Also, I can pull the wire off the sender and nothing happens (it will stay at full).
I have ran an extra ground wire from a fender bolt to one of the bolts that hold the sender unit in place. The wire from the top of the sender is going
to the tab on the drivers side of the fuel gauge. I have power from fuse 8 going to the vibrator which is attached to the tab on the passenger side of
the gauge. I'm pretty sure this is correct.

I took everything back out and did some more test. I found that when I touched the metal housing to ground, the needle would go all the way to full.

Sender close to the empty position.

Sender in same position, but with a ground wire touching the housing.

So when the gauge is installed the housing is touching the speedo, which is grounded, and messes it all up. Should this be happening? Am I missing
some rubber insulators or something? Maybe it's just a bad gauge? Anybody got any ideas for me? Thanks!

Thanks for the pic of the 68 speedometer. It got my 66 working. I had a wire in the wrong place and messed up my flashing light for the blinkers. Had a "glow" in it all the time. No more. Thanks again to all of yall who have walked before me.

so it looks like I have to get the sealant for the screw to, I looked at the sender unit, it looks like there is nothing under the screws, but I will put a ground to be sure. Indian head sealant? I guess I will at the automotive place to see if i find it or something like it, and ground the other end on the chassis.

[glutamodo]

If you run a ground, make sure there's no plastic gasket underneath preventing it from making contact. I was going to post the picture of the tank unit in my Baja, in which I did both, ( but the only reason I did the extra wire was because I was having issues.... which turned out to not be because of a ground, it was a burnt out gauge. )

[runamoc]

Or just run a ground and be sure. That brown stuff is Indian Head gasket sealer, don't want any leaks.

Tank unit ground: If all of your sending unit screws have washers under them that are made of plastic, then yes you'll need to do something to ensure a ground. The easiest way is to use a copper washer in place of one of the plastic ones.

I just posted pictures of the speedometer, with the fuel sender unit, and voltometer unit.

My question is do I need to ground the fuel sender unit on the gas tank?

the wires going to the vibrator unit are:
on the right: black wire from a lamp unit to bring in power...

on the left: green wire from the sender.

am I missing anything?


I saw that a person had a ground from the sender unit on the tank. but the previous setup i had on my unit did not have this.


For the voltometer:
I encrusted it into where the old gas gauge was.
I do have a whole bunch of wires that went to it.
right now I have a ground to the chassis, a bulb with a black wire,
and another wire that is going from my speedometer (red light connection) to the voltometer

The voltometer is VDO, it has
I (where I have put the wire from the speedo to, thinking I means indicator???) S (where I have nothing), the bulb where I have the bulb and i used one of the attachments G as a ground to the chassis.

is this set up okay?
