Quote: I am not sure I agree, I would rather have one reliable, properly sized, tested/measured ground, then, unless in an in an emergency, a random selection of undersized, maybe good grounds, and let the electrical devices figure which one is best. IE, if a ground is thought to be not correct, then any additional backup grounds have to all be the same proper size, thinking you can "share" or combine grounds is unwise and asking for future problems.
"static straps", are primarily for grounding static charges, not grounds.
My point was not to have a bunch of undersize grounds. My point was its nothing wrong with adding a ground of the correct size even if you already have a ground of the correct size in whatever circuit you are working with. Hence the saying .....you can never have to many grounds. Ron
I believe I understand your overall point, but the problem I see is when one has multiple grounds, often for extra assurance/back-up/whatever, unless they are all sized for the largest possible current demand, when one of the redundant grounds becomes less effective (corrosion, intermittent, loose, disconnected in error, etc), the current will then seek another ground with less resistance, and IF that ground is undersize, issues arise. Therefore My concept is just to have a single "great" ground path, and if a problem with that ground arises, the effect is immediate and maybe very obvious, and likely in a single location. That's why having a "lot" of grounds is not a goal for me.
I understand your point also. I guess what I like about having a second proper ground is I kinda look at it like back-up. Like an eng to body ground. If for some reason one is left unhooked or the bolts left loose then with a back-up ground everything will still work. And if both are done right and working with good clean connections even better. Not saying do it as a bandaid just that it cant hurt. I dealt with alot of body ground problems over the years working at the Dodge dealer where even with a good looking tight connection you could only find the problem doing a voltage drop test. We had problems with Dodge Vans doing some weird things and finding grounds through the strange places causing some trans and wheel bearing problems so I always made an additional ground and put it on them myself after cleaning the factory ground.
