Need help urgently from those that have fitted Barry's earth kit.

The wire that is labeled A-O-P in the kit shows it going from the earth point on the chassis rail to, I presume the Trans then to ????. The end of the cable is labeled P, it has an open ended spade connector.

I nearly have the kit installed but the instructions are a little blase.

Cheers

To be honest I would not bother installing this rubbish and making your engine bay look second rate

I have had the oppertunity to look at one of these first hand and they do nothing that the factory earthing system does not already do.

I believe he earths the Trans, the ALt bracket (This may be where this one goes) and for some unknown reason the dist. The one I looked at also had an earth to the block and the fuel rail for also some unknown reason. Both heads are earthed also

Before you put it on, start the car and use a multimeter to test for voltage differences between the points the kit is meant to connect. If there is none, don't bother putting it on. Let us know if you do find any voltage differences.

Hi Craig - I have just replied to your PM and all the necessary info can be found there

It was just a matter of late labelling changes when trying to catch the P.O. before closing

The open ended connector goes to the forward distributor mounting bolt

Let me know how it all goes for you

Thanks, Barry

Barry I have just sent you a PM with a further question.

Thanks

Craig

Do as MadMax stated but this just in, the dist in these cars is so well earthed, you could run a 3 phase cable to the dist it would make no difference.

Test all of your points on your car, I have asked Barry on numerous occasions for actual figures of voltage drops and in what places these drops occur however to date have never really had a reply even worth the time it took to read

Also be careful on how you mount the cables as you can do damage if they are not mounted correctly, if the dist is not correctly mounted for instance it may leak

Mal,

Now not that I believe these kits do much/anything (got two of them for testing), but let me play devils advocate.

Maybe you have been asking the wrong question? If it does as he says fix some issues a multimeter is probably never going to show you a difference, really it would have to be tested with an oscilloscope and someone that knows exactly what problem they were looking for.

And what do you want to measure with the oscilloscope? What "problem" is Barry's kit supposed to fix? I can knock up any gauge wire with any connector on it and join any part of the engine to another, but why would I want to? Some hard facts required here!

I do not want this to turn into another Earth Kit bashing thread. I was just after some fitment information as I had started to fit the kit and needed to complete it ASAP as I needed the car.

I will say that I have read some articles about earthing, one in particular comes to mind where the tested vehicle was a Ralliart Magna. Coupled with the fact that MMAL offer earth kits as optional accessories on their imported cars, I thought what the hell there could be some merit in this. So with the positive replies from those that have fitted Barry's kit and the fact that it is virtually hidden I took the plunge.

Moderators please close this thread, as have the fitment answer that I was after.

Cheers

Craig

Is it "earth kit bashing" if I ask for information? I'm asking for someone to do some valid testing on the engine to see if earthing can be of any use. A request for INFORMATION by an open minded person can never be considered BASHING, unless this is used as a smokescreen to avoid providing scientifically verifiable data!

Voltage differences across various points while the engine is running would be more valid.

If this thread turns into an "Earth Kit Bashing" thread, it will be closed!
While we are discussing the facts it should remain open.

Let's focus on investigating the original problem it's designed to resolve, and what the verifiable benefits, advantages, improvements, it delivers.

There are lots of value adding engine improvement ideas in this world - some good, some bad.
Our aim should be to verify which are good & bad so we don't waste our hard earned $$$.

Voltage differences across various points while the engine is running would be more valid.

I did that also, with a scope (to check for higher frequency noise) and DVM, found negligible drop (few mV max) except when cranking there was ~200mV drop on the ground to the starter which is understandable considering the current.

Thank you Mr Cummins. Your investigations confirm my feelings about earthing kits.
Anyone who believes this kit works, is free to purchase and install it. I choose not to.

A member has wisely pointed out, this is the Tech section and we should stay on topic.
The topic of this thread was the Earth Kit but it was for a specific problem, not the pros/cons of the kits in general.

We don't mind a discussion thread on the pros/cons of any car/engine mod (as long as it doesn't turn in an argument) but this is in the Tech Section and threads should stay on OP topic.
