I agree. They are relatively inexpensive, and it is a good starting point for eliminating the problem. I learned last weekend that grounding problems cause the majority of the electrical demons we think possess our cars, haha. I spent the better part of last weekend replacing what I thought was a dead starter, only to find out that my problem was mr. yucky green corrosion on my negative battery cable. Every time I went to start the car, the starter would either click, or just barely turn over and then stop. In my case, I simply stripped the negative battery cable to expose new, clean wire; then I hooked it all back up and started up with nooooo problem!
