Hi guys

I am slowly tracking down a number of issues with my newly purchase 1967 1916cc beetle.

Whilst having a look under the car I noticed that it does NOT have a Transmission to Chassis Ground strap.

From my "googling" I assume that this is not desirable as it can cause a variety of problems include using the accelerator and clutch cables as "earth" cables that can cause them to heat up!

Also, yesterday I was at the auto electrical place having my VDO electronic speedo fixed and I asked them about the accuracy of oil temperature gauges. I was told that it was very important that they rear of the car is grounded correctly otherwise the accuracy of the gauges will be affected.

Looks like I'm off to Vintage Vee Dub Supplies tommorrow!

If it has a solid mount it would not need one

Like in the pic but without the red poly bits

Definitely get one as ever time you start the motor, all the amperage required to the starter motor will be tying to use the other paths that you mentioned.

Thanks guys

Bizarre, it uses the standars rubber mounts.

I got a strap from supercheap. they have universals... does the job well

Yea, Supercheap one works perfectly well

I think the chassis is M10 stud and gearbox uses M8 studs so if you can't find a strap with those ends then buy one with 10mm holes either end and use a few penny washers on the gearbox lug

Thanks guys

Should I use 2 or just one? Is 2 going to be even better than 1??!

Regards Greg

It is SO important that VW uses a plated stud and nut and washer on the tranny especialy for better conductivity.

Hi Dave

This is the gearbox that you did for Stenguns back in 2009 for his 1967 car.

I just had a look at the Bentley manual for a 1967 to see where the ends of the strap connect and I can see where it connects to the transmission...where is the best place to connect to the body side of the mount?

Also, is 2 better that 1 strap?

Hi guys

Here is the latest update.

I went and purchased 2 straps and fitted them to the transmission.

I have attached a photo.

Wow, that's really getting down to earth.

Yep! I thought that it would be better to go over the top and make sure that I wasn't going to have an issue with a bad earth.

Greg

So you have Stenguns blue car or just the gearbox ?

that'll keep ya trouble free for many moons

Hi Daimo

I have the whole car. I purchased it just before Xmas and am in the process of working through a list of "issues" with the aim of getting it to be a reilable daily driver.

Ahhh okay..... I passed you when you were driving back south then...... A km or so south of nambucca and gave you a wave from my white beetle.

Good looking ride, was glad to see it out and about

Ha!

Small world!

Greg

Update

I just took the car for a test drive and there is a big difference with the reading on the AMP guage.

Prior to installing the earth straps, it was reading just under 12 volts, now it is reading almost 13 volts.

There's nothing like a bit of overkill

Also, as an aside, yesterday I was getting my VDO electonic speedo fixed and asked the guy to check the other gauges and I asked him how accurate the VDO Oil Temperature gauges were. He said that the gauges and senders are very accurate that that it was very important that both the front and the rear of the car have a good earth otherwise there will be a difference in impedance and that can cause gauges to be inaccurate....
