I agree, I don't believe it is always necessary to solder. If you want good connections then try compression fit terminals.

I think I need to make it clear that I am not debating the issue of what is a physically strong connection. Both compression and crimp have their merits.

How will a compression fit minimize corrosive effects over time the way that soldering would? The copper strands are still exposed to the elements in this condition and are not shielded from air & water as they would be if the copper wire was encapsulated by the solder.

This is all about reducing corrosive effects and the resulting increased resistance that the wire will bear over time. The physical strength of the connection is not my concern.

Anyone who has found a copper penny that was exposed to the elements over time can see that the integrity of copper is greatly compromised without protection, especially in the areas where good electrical contact and conductivity are the requirement.

My rational is no different than the practice of keeping battery terminals clean or sanding the ground areas for good electrical contact.

The performance of a crimped connection versus a soldered connection will be essentially the same in the beginning, but depending on your cars exposure to a salt environment (sea or snow) there's going to be a degredation over time which you will not be able to tell the loss because of it being a gradual affect.

Checking your cable to see if it is dark / blackish or even green is a sure sign of degredation.

This grounding mod has little if any effect on the performance of your car, so if you just crimp the connections, it's kind of pointless.

No, you're not the only one. I wondered about the advisability of doing that too. Since these cars are ( - ) ground wiring system, that would create a direct short across the battery's ( + ) and ( - ) terminals. Now my old Triumph TR 3 was wired with ( + ) ground. Those kooky Brits

4 gauge is what most grounding kits are.

Question for the people who installed a ground kit.

If you search the sounddomain forums there is a sticky regarding ground wires (Big 3). They suggest people put a fuse between the +battery and the alternator.

My question is this. Do the kits people here purchased take this into consideration?

Thanks,

Mine should be here soon, lets see if it does anything !!!

Guys,

I did this on my SC400 with the techkit. Didn't notice any difference whatsoever and I think it looked pretty bad also.

As for mounting points - it really doesn't matter!!! You can ground whatever the hell you want to ground!! Choose the major electrical things on your engine bay and run a ground to your chassis. Eg. put one on each side of your intake manifold to chassis.

You are not going to hurt anything by grounding it.

I ended up using self-tapping screws to go into some parts of the chassis because the bolts were no long enough.
