Earth/ground straps

Hi Guys,
I am in the process of cleaning up all the earth straps on my cars.
I would like to apply some sort of protective goop or sealer between the cleaned up bare metal and the earth strap in order to stop it from corroding. Much like the stuff recomended for battery terminals.
What about copper seal or something similar? Any suggestions will be much appreciated.
 
I like this stuff.

Bob

i am with Bob C all the way. Expand his pic and look at the label. It is made for the purpose. A conductive anti-oxidant paste. Silicone grease will keep corrosion away but is not conductive. And whatever you use, be sure the connections are as mechanically tight as you can get
 
TKS Gents,
Thats what I want. I'll use the 'red battery stuff' in stead of the silicone dielectric grease because I would prefer the conductive stuff.
I hope it's available here.

Because it is conductive and it might shock you (depending on the voltage in the wires). A 6 volt battery will not shock you. But it can be used for other things, at much higher voltages.
 
I know you weren't asking it, but I'll share this with you anyway. I put an auxiiary ground cable on my three As. I tried one (car) and I liked it so much I put it on the other two. I used the inside of the frame flange and connected both ground cables with the same (Brass) bolt. I ran the other cable to the bell housing bolt to give a more direct path. It seems to spin a little faster and the battery seems to run a little bit longer. And I used silicon Dielectric paste on the connections.

"Why does that Kopr Shield say warning do not apply on live wires?"

The product can be used on a system of any voltage. However few people want to apply it or anything else to live wires with say 120 V or 240 V.
But most cars have low voltage systems such as 6, 12, 24 volts, which cannot shock you.
However, the voltages of the electric cars and hybrids is quite high and can toast you good; stay away

TKS Terry,
Much appreciated, I have also taken an earth wire direct to the frame on one of my cars. Can't remember which one, but I'll check and do the rest as well.

AND TKS Guys for explaining the 'Kopr Shield live wire warning'

Have a great Sunday chaps.

yea thats my project this fall is to run a dedicated ground strap from either side of the bell-housing to each frame rail. More dedicated grounds the better. there is not a good ground path on the model A in stock form by any means...
 
On Model A's, you can never have TOO many grounds, if you can do it in a nice HIDDEN way.
Chief always pulled hidden, dedicated grounds, through the headlight conduits & the tail light looms.
Grounding problems were NOT so common, when the cars were NEW & All the metal parts were SHINY NEW!

I have an extra ground ******** my A. As I remember I put a little dielectric grease on the connection but now I wonder if I should have used something else like the Kopr Shield mentioned. Should I redo it and what is the proper use of Dielectric Grease?
 
dielectric grease is a protective coating (anti-oxidant) as is Kopr Shield. There are several brands similar to Kopr Shield out there, I use the stuff from the electrical isle at Lowe's.

The only difference is one is conductive and one is not.
For household voltages ie 120-240 volts you don't really want a non-conductive coating; you are not trying to insulate the connection, but rather, improve it electrically. To me, the same principle applies to car voltages 6-12-24. But if you cleaned the chassis to shiny bare metal, and really torqued down the mounting bolt for the cable, and applied dielectric grease after to the outside of the connection, and the starter turns easily, then I would leave it alone.

Just remember that a proper electrical connection needs to be both electrically and mechanically sound

If you have dielectric grease on there now and the starter is not dragging then I would just leave it alone.

Agree with Dave,,
I used dielectric grease on my whole house generator electrical connectors to seal out any moisture from corroding the electrical pins. I also use it on spark plug boot wires to seal and protect the connection and also it makes for easier removal of the plug wire in then future. Most ignition wire sets come with a little tube of it...its also used on the mating surfaces of ignition modules on certain applications..
as stated if it aint broke dont fix it....we just love to fiddle huh
 
I've put never seize on ground and battery cables for about 40 years. It stops corrosion and is a good conductor.
