Grounding across frame welds
Has anyone experimented with the resistance across welds or various parts of the chassis?
Because if a welded joint in the frame were to slowly corrode or get dirty it could build resistance and screw up the grounding plane of the car.

BTW you should read the old threads on 3k hesitation.
I've got it, and I will improve the engine->frame grounding connections. I'm just wondering if anyone has ever tried checking/improving the frame->frame connections.
This topic is relatively simple compared to the old discussions.

There is no way to test the electrical resistance of the welds because there is no way to isolate them.
And I agree with FormerPorscheGuy; you're thinking way too much

The resistance from any part of the engine bay to another part of the engine bay, when properly grounded with stock grounds, is so low it's not even worth making an issue about it.
I seem to remember seeing around .1 ohm or around there when testing from the fender to the top of the engine.

I will look for any bolted connections though and see if there is significant resistance across them.
