Glad you liked the mod, Lynn. I'm not really sure I can feel any big change, but it was sure fun to do. And, it SEEMS like it should do better at high RPMs.
I saw a post in another forum that talked about touching the positive cable to the negative post. It gave me a "queasy" feeling, but I couldn't really see any super harm. I DO like Bill's opinion though. From personal testing, there's a lot of things sucking current all the time, so very soon after you disconnect the negative cable, the whole system is going to be dead.
And, boy; if you should happen to touch a ground while unscrewing the positive terminal (with the negative still connected), the number of amps that would suddenly try to go through your wrench would probably light up a whole city! OK, not quite, but the spark and heat would be pretty scary!
